How to refill a powder cartridge on a canon printer. How to refill an inkjet printer yourself. What you need to know about refilling laser printer cartridges

In this short article you will learn how to refill a laser printer. Any user can carry out all the work independently; nothing is complicated. But you need to know how to use a screwdriver and sometimes pliers. Now we will look at general recommendations for refilling toner cartridges. As an example, the most common printer models that are most often found in offices and homes will be given.

Features of refilling HP and Canon cartridges

Perhaps the best laser printer for the home is one made by HP or Canon. There are models that are very similar to each other. Refueling is carried out according to the same algorithm:

1. Take out the cartridge.
2. Remove the side panel of the cartridge by unscrewing 1-2 screws.
3. You also pull out the photoconductor.
4. Pour new ink toner into the hole, which is covered with a magnetic shaft.

Reassemble in reverse order. Most cartridges have a refill hole; it is covered with a plastic plug. It is worth noting that when refueling you do not need to change the chip or reset the counter.

Samsung and Brother printers

These brands are a little more demanding when it comes to refilling, especially Brother. With Samsung, everything is very clear - the cartridge needs to be disassembled and new toner must be poured through the filling hole. In this case, no other manipulations are necessary. But you need to know how to refill a laser printer cartridge yourself if you have Brother. First, you will have to disassemble the cartridge and pour toner inside. Be sure to empty out any remaining waste in the waste bin. You can reuse them - it's not critical.

In addition, this printer model has a built-in system that counts the number of printed sheets. Moreover, when the threshold value is reached, printing stops completely. Fortunately, such a “breakdown” can be eliminated with simple manipulations:

1. Turn on the printer.
2. You wait until it starts and shuts down (all the internals stop rotating).
3. Press the “Back” and “Up” buttons.
4. Press the “Down” button several times until “00” appears on the display.

That’s it, press the “Start” button and get to work. The counter is reset to zero and you can continue printing. Refueling is not necessary at all.

OKI Printers

These printing machines are different in that they also have chips installed. These are small boards with chips that set the resource (the maximum number of pages that can be printed). As a rule, it is necessary to replace the chip every time the cartridge is refilled. Now we’ll talk about how to refill laser printers of such models. First, let's talk about finicky OKIs:

1. Refilling is necessary infrequently, since the cartridge has (like all others) two hoppers - for clean toner and for waste. But to save money they are connected to each other. As a result, the toner takes a very long time to be produced.
2. The cartridge has a microchip installed. When a certain number of printed pages is reached, the printer simply stops. Therefore, the chip needs to be replaced.
3. In addition, sometimes (about once every 15,000 sheets) the printer begins to “swear” at the cartridge. Only installing a new element will help. But you can also cheat. New cartridges have fuses that burn out the first time they are turned on. The printer “sees” the new cartridge and starts counting again. To deceive the printer, it is enough to close the corresponding contacts and open them in time when turned on. It is convenient to use an ammeter for this purpose.

Xerox Printers

These printing machines are also capricious, but not as much as the previous ones. How to refill a Xerox laser printer? This is very easy to do - remove the cartridge and add new toner. Moreover, sometimes you don’t even have to disassemble the unit - the filling hole is in plain sight. But the problem is that you will need to install chips. Their cost is quite high, but some technicians manage to programmatically eliminate the need to replace the chip card.

Now you know how to refill laser printers of various models, and what nuances you may encounter when doing so. If you are not confident in your abilities, take the cartridge to a workshop - they will do everything much faster and will also provide a guarantee for the work performed.

Inkjet printer ink is one of the most expensive supplies needed to keep your home office running. You, like any beginning photographer, create hundreds of beautiful photographs, copy them to your computer and print them. It is a very sad situation when the printer runs out of ink. In this case, you have two options:

• Buy new cartridges;
• Refill the cartridges.

By following our instructions, you can save a significant amount of money on new cartridges for your device, namely on the purchase of cartridges. Refilling the cartridge yourself is many times cheaper than buying a new one.

1 The first step is to purchase a set of color inks. Ink can be purchased at your local store or ordered online.

2 Organize your workspace. Prepare a roll of paper towels and some wide tape.

3 Open the printer and remove the cartridge from the printer. While you are working with the cartridge, close the printer to prevent dust from getting on the exposed parts.

4 Wear gloves when handling ink and cartridges. They will not allow you to stain your hands with ink, which is very difficult to wash off from your skin.

5 Tear the required amount from the paper towel and fold it in two. Working on a paper towel will keep ink off your desk. Which, as we already know, are very difficult to wash.

6 Place the empty cartridge on a previously prepared towel.

7 Carefully read the instructions that come with the refill kit. From it you will learn how to properly refill your particular type of cartridge. Below are general instructions for refilling ink cartridges.

8 Remove the sticker from the cartridge and locate the ink holes. Different cartridges may have several holes, but only one leads to the ink reservoir, see which one in the instructions.

9 To uncork the ink reservoir, use a toothpick or needle. Pierce the protective layer and you will have access to the tank.

10 When refilling a color cartridge, be careful to fill the correct ink into the correct reservoir. Color cartridges use three colors of ink:

• Magenta ink;
• Yellow ink;
• Turquoise ink.

To determine the color in the reservoir, dip a toothpick into it. After which you will know exactly which color and where to fill it.

11 Fill a disposable syringe with ink from a can, the required amount of ink individually for each type of cartridge (see the instructions). Also, make sure that foam forms in the syringe and that there is no air - this can damage the cartridge.

12 Insert the syringe needle into the required hole, about 1 centimeter, and slowly inject the ink. Be careful not to overfill the tank.

13 After injecting the ink, remove the syringe needle. If you have poured more ink than necessary, carefully blot the excess with a napkin.

14 Clean the ink cartridge contacts with a paper towel.

15 After cleaning the cartridge, seal the openings of the reservoirs with pre-prepared tape.
Blot the cartridge nozzles again with a paper towel until you are sure that the ink has stopped leaking.

16 Place the refilled cartridges back into the printer.

17 Close the printer cover. Then from the printer settings menu on the computer. Start printing a test page.
If the printed sheet does not contain any blemishes and displays all colors efficiently, this means that the process of refilling the cartridge was carried out at the highest level.

What you need to refill ink cartridges:

• Ink cartridges;
• Refill kit;
• Roll of paper towels;
• Narrow tape;
• Toothpicks;
• A pair of disposable gloves.

It often happens that the inks of a new printer run out after several months of use. And the user is faced with the question: buy a new cartridge or refill an old cartridge.

How to refill a cartridge yourself without resorting to the help of specialists?

Can the cartridge be refilled?

Many companies, when developing printers, know that the cartridge is the heart of such devices and without it, printing documents or photographs will be impossible.

Therefore, we foresaw in advance the possibility of purchasing new spare parts.

As a rule, such devices are very expensive, sometimes more expensive than a printer.

You can refill the cartridge yourself, however, this is a very troublesome and time-consuming task.

The speed of this procedure depends on the type of printer and cartridge model.

The older the model of both devices, the more difficult the work.

It is worth noting that it is better to refill some cartridges of inkjet and laser printers with professional technicians who know how to refill safely and without breaking expensive equipment.

Sometimes it is better to replace printing containers with powders or inks with new ones when it comes to the tenth change of ink or a complex procedure (when it is not possible to carefully make a hole in the container or there is a possibility of damaging electrical contacts, etc.).

How to refill the printer

Refilling an inkjet and laser printer cartridge

In addition to the fact that you need to take the printer’s instructions, before refilling the cartridge yourself, you need to study the properties of its operation, and when performing the procedure you will need the following things:

• Empty cartridge;
• Ink in tubes or jars;
• Paper towels;
• Medical surgical gloves;
• Alcohol for wiping surfaces;
• Cotton pad or swabs;
• A syringe with a thin needle.

Instead of cotton wool with alcohol, you can use wet wipes. In this case, you need to act carefully so that water does not penetrate into the ink holes.

It is important to note that more than one syringe may be needed if we are talking about filling several containers of paint.

For a laser printer, in addition to the specified set of available tools, you may also need a needle to make holes in the compartment.

Also, a small self-designed spatula to pour colored and black powders into the container with substances.

What you need

How to refill an inkjet printer?

The inkjet printer is ubiquitous in many homes due to its ease of operation.

It makes it easy to print photos and make documents. The only drawback is the speed of printing documents.

Before you start refilling your inkjet printer with ink, you need to choose the right blueberries.

The instructions usually indicate which model of cartridge was inserted.

You should buy paint based on the model.

Unfortunately, printer manufacturers do not produce ink, so you need to carefully select it from intermediaries.

It is better to give preference to more expensive models to avoid poor printing, dry nozzles and a faulty printer.

You can refill an HP cartridge step by step:

Remove the cartridge by pressing the button that locks the cover;

Removing the container

Examine the tank and select the compartment required for refilling (black or colored).

As a rule, they have stickers with holes for ink underneath them;

If there are no holes in the paint compartments, make them yourself using a needle;

Making holes with a needle

Take out a syringe with a thin needle and draw exactly 2 milliliters of paint into the syringe.

Insert the needle to the middle and slowly introduce paint into the compartment (fast introduction of paint will lead to damage to the device);

Filling the reservoir with a syringe

Avoid the appearance of bubbles and spillage of liquid; do not inject more than the specified amount.

If the container is overfilled, remove some of the paint with the same syringe.

Remove excess liquid

Wipe the base with alcohol and return the sticker to its place.

Wipe the tank

If you need to refill a Canon printer cartridge with a color print head, you need to take three different syringes and label them so as not to get confused.

Pour 2 milliliters of paint into each syringe and carefully insert them into the corresponding holes. At the end, also treat everything with alcohol.

How to refill a laser printer?

The laser printer has a high printing speed. Has better print quality.

Its price is higher than inkjet, but it can fully pay for itself. Unlike an inkjet printer, a laser printer does not add paint, but powders.

You need to work with them carefully, as there is a risk of poisoning. All work must be done in a room with an open window.

You can refill a laser printer cartridge step by step using the following instructions:

Remove the cartridge and inspect.

Removing the paint tank

Pry the cap off the device with a needle and open the container.

Opening the container

Pour the powder into the hole and close with a stopper. Remove any remaining powder from the surface and place the container back into the printing mechanism.

Fill the cartridge with powder and remove excess

If a laser printer does not have a plug, but has a hopper and toner, then the instructions for refilling it look different.

As a rule, it is better to entrust this matter to a professional, since there is a high risk of damaging the print head of such a mechanism. There are certain nuances here.

Firstly, you need to make the correct puncture in the hopper where the printing mechanism and the container with powders are stored, and secondly, you should select a place for the hole that is distant from the chips with microcircuits.

First, you need to pull out the device, make a hole with a scalpel or drill, away from the microcircuits, and then insert a funnel into the hole for refilling.

To avoid damaging the printing mechanism, you should then try to completely disassemble the cartridge and find the slot where the powder refill should flow.

Interestingly, the second option is also not safe, since the photocell can be exposed and damaged.

For this reason, it is not recommended to refill such a printer yourself.

This can lead to the fact that printing will deteriorate dramatically and the printing mechanism will be completely disabled.

To avoid making mistakes, it is better to entrust the work to a professional, replace the cartridge with a new one by ordering it from a trusted company, or use a training video where experienced people show proven techniques on how to refill an inkjet and laser printer cartridge.

How to refill an hp printer?

HP printer comes in inkjet and laser. The method of refueling them does not differ from that presented above.

It differs from other devices in that it requires 2.5 milliliters of paint or powder to achieve the desired effect.

How to refill a canon printer?

The most popular Canon model is the PIXMA MG2540S. This is a jet device, the filling principle of which does not differ from the general instructions.

Before starting work, you need to open the cover with the heart of the system, and then turn off the device from the network and carry out all operations.

Upon completion of work, check the work twice by making two prints of the document.

How to refill a brother printer?

Today, the brother HP Neverstop Laser laser model without a cartridge is gradually spreading.

It is refilled through a special refill toner, which is inserted into the refill compartment on the right when the device displays a warning icon that the ink is running low.

All that is required from the user is to insert the device into the compartment and wait a few seconds.

How to refill a Lexmark printer?

The Lexmark printer comes in two types. There are laser and inkjet.

Its difference from other models is that refilling is possible no more than 5 times. In the future, you need to change the cartridge.

How to refill a Samsung printer?

Samsung is the most common brand in all offices in the country due to its reliability and ease of use.

Refueling is carried out using the same method as other devices. It can be done no more than 10 times. Then you need to reflash the cartridge chip

How to refill an LED and dot matrix printer?

The only difference between an LED printer and a laser printer is that in the former, an image is drawn on the photodrum using LEDs.

In both cases there is light. Refilling occurs using powders.

Therefore, the filling scheme is no different from that used for laser devices.

Most LED models print in black and white ink, but there are also color models.

Therefore, printing mechanisms contain not one toner, but several.

LED models are used both for home use and for office needs.

They are good in that they are able to quickly print large volumes of graphic information.

A matrix device is a type of inkjet machine, but unlike the latter, it has worse print quality.

Today it is practically not produced, since it is in the lowest demand due to high noise, slow speed, poor printing and lack of color.

It is refilled using the same technology as the jet device.

You also need to turn it off, pull out the container, open the sticker with holes and pour black paint into a special compartment using a syringe.

As is the case with other devices, everything must be done as carefully as possible, since there is a possibility of damaging the device.

Differences between LED and laser devices

Warnings

When refilling, do not touch the protruding wires and printer contacts located below and in front with your hands.

If your hands are oily, contacts may be broken and the printer may stop printing efficiently. Rubbing alcohol can fix this.

In addition, you should never insert an overfilled brother cartridge into the printer system.

This may cause irreversible damage to the entire device.

After refueling, you need to make sure that everything was done correctly.

You need to print a few test pages. If you fail to print the document the first time, you should try a couple of times.

The flow of ink into the printing mechanism may take several prints.

It should be remembered that ink must be removed using a special solvent. It is dangerous for the delicate skin of your hands.

In addition, it can ruin clothes. Be careful and be sure to wear gloves.

Important! The printer must be recharged while it is off.

Otherwise, in addition to the fact that things may be dirty, thermal burns, hand injuries and other unpleasant situations may occur.

Correct refueling

When starting to refill the cartridge, be sure to consider the following recommendations:

If, after refilling the cartridge, lumps appear that prevent ink from flowing into the device, then you need to use this method. This is a last resort before purchasing a new device.

You need to take a new syringe, remove the plunger and insert the syringe as deep as possible into the base of the cartridge.

Take air into your mouth and blow into the syringe to force air into the device.

In this case, it is necessary to prevent the incoming ink from overflowing.

After filling the device with air, you need to shake it, covering the holes with a paper towel. Repeat this several times if necessary.

The weight of the refilled cartridge should match the weight of the new one.

If the device is full of ink, it will break before the specified end of life.

The cartridges hold the ink using a special sponge.

If you overfill the edges of the device, liquid will flow out of the sponge and flood the printer. This will negatively affect his work.

If the refilled Lexmark cartridge did not give the desired results and the document was not printed, then you need to use the following method:

Use a syringe to inject a few drops of alcohol, pushing the needle as far as possible. This method will get rid of dry cartridges, ink clots and other problems.

If the first and second methods did not help in restoring the printer’s operation, then you should go to message boards and find exactly the same printer.

Typically, the printer costs less than the cartridge.

You can pick up a new cartridge from this device and install it on your printer.

This way you will get not only two printers, but also two new cartridges that print with black and color ink.

Don't be afraid to pour ink into your old cartridge and try to get it working again before you buy a new one.

Purchasing a new device is not only expensive, but also time-consuming. The fact is that in order to get a new one, in many cases you will need to send the old one by mail.

If a specific color is not used when printing a document, the problem is with the print ribbon.

It can cover the holes where the ink comes from. It must be removed and returned to its place, eliminating the vacuum that prevents normal printing.

Do not allow the ink in the cartridge to dry out. You need to regularly print something through the printer, at least once every 7 days, and do diagnostics.

After the tenth refill, the print head may become unusable.

Therefore, it is advised to still buy it in such a situation.

Finally, a piece of advice: you can refill a Samsung cartridge, but you need to do it slowly to avoid the appearance of bubbles, which reduce the quality of printed documents. In this case, it is necessary to completely de-energize the device to avoid short circuits, failure of the device and the formation of microtrauma in the eyes and hands.

Conclusion

In general, there is nothing complicated about refilling a cartridge with ink.

The main thing is to follow safety rules, research the printer design in advance and act according to the instructions.

How to refill a laser printer cartridge

In our world, every company tries to find profit in everything. Thus, in the computer industry, printer manufacturers receive most of their profits not from the sale of office equipment, but from the sale of components for it. For example, HP receives the lion's share of profits from the sale of printer cartridges.

The reason for this is that when purchasing a printer, the buyer receives a demo cartridge, which is not only half-filled, but also “refuses” to be refilled after the toner or ink runs out. And while refilling an inkjet printer cartridge is quite easy, you will have to tinker with laser printer cartridges. How to refill a laser printer cartridge?

Useful "rules"

In fact, there is nothing complicated about refilling cartridges. It is enough to understand a couple of rules and follow precautions, since the toner used to refill laser printer cartridges is harmful to health.

It will not be possible to refill chipped cartridges for the first time at home, since the chip will need to be replaced and “cancelled.” It is better to contact specialized companies for this, where they will replace the chip and refill the cartridge.

If you are not well versed in technology, it is not recommended to refill the cartridge yourself. Not everyone is capable of assembling/disassembling equipment, and if you scratch a sensitive element, you can completely throw it in the trash. Therefore, if you are not sure that you can refill a laser printer cartridge yourself, it is better to trust the professionals. Save your health, nerves and cartridge.

There is no universal toner. As a result, you need to purchase exactly the toner powder that is suitable for your printer model. Don't worry, the toner packaging usually says "supported" types of cartridges.

Precautionary measures

As mentioned above, toner is very harmful to health. Do not allow it to get on your hands or into your respiratory tract. In this regard, it is recommended that you wear rubber gloves and a robe while refilling so that the toner does not get on your clothes.

Refueling should take place in a well-ventilated area. You should definitely wear goggles over your eyes, and a respirator or gauze mask over your nose and mouth. Alas, even a gas mask will not hold the toner powder, so you need to be careful when refilling and try not to spray it. But don’t worry or worry too much about your health. You won't blow it up just by refilling it.

Remember that toner should be stored under normal conditions and at normal temperatures. If moisture gets into it, it will cause the powder to “clump.” Cartridges cannot be refilled with this toner. If lumps appear, close the toner bottle and shake it.

Refueling process

Refilling a laser printer cartridge yourself is not as easy as it might seem. There are three types of cartridges:

To refill some, you just need to remove the cap and add toner;

To refill others, you will need to completely disassemble the entire cartridge;

To refill chip cartridges you will need the help of professionals.

In the first case, refilling the cartridge with toner will not take even ten minutes. Place a newspaper on the table or floor and remove the cartridge from the printer. Then unscrew a couple of bolts and remove the special plug from it. Then we fill in the toner purchased at the store and insert the plug into place. Shake the cartridge, wipe off any remaining toner with a dry cloth and insert the cartridge into the printer. That's it, the laser printer cartridge is refilled.

In the second case, refilling will take longer, since you will need to completely disassemble the printer cartridge. On the Internet, for each type of cartridge there is a diagram for its complete disassembly. The principle of disassembling the cartridge comes down to the following: remove the cover, move the metal arms apart and pull out the photosensitive drum, which should not be touched with your hands. After refueling, all this is assembled in the reverse order.

Some experienced users prefer to drill a hole in the cartridge and fill it with toner. But to do this you need to know where to drill. Therefore, you should resort to this method in extreme cases.

Refilling chipped cartridges at home is impossible, as it requires flashing or replacing the chip. If it turns out that you are unlucky with the cartridge, then contact a specialized company to replace the chip. After which you will be able to refill the cartridge yourself using the above methods.

The main thing is to take care of your health when refilling and avoid getting toner on your hands, face or respiratory tract. A new cartridge can be bought in a store, but health cannot.

Office equipment manufacturers strongly recommend purchasing a new printing unit when the old one runs out of toner. But the high prices of original products make users wonder: can HP cartridges be refilled? Definitely yes. But to maintain print quality, it is important to strictly follow the rules, which we will talk about later.

Refilling methods

You can choose one of two options:

• the cheapest is to refuel yourself;
• It’s a little more expensive to contact a company that professionally provides this service.

Toner for HP cartridges

The ink powder has the greatest impact on print quality. Hewlett Packard's expensive original polymer toner is chemically synthesized. It has a finely dispersed structure and an even spherical shape of microscopically small particles.

In search of more affordable options, you can buy compatible powder for HP printers, which are produced by AHK, IPM, Integral, Kaleidochrome, Katun, MK Imaging, TTI, WWM. TM Static Control has proven itself well.

When deciding which toner to refill HP cartridges with, be sure to read reviews about it on specialized forums. In addition to compatible ones, you can come across cheap but low-quality counterfeit powders from unknown manufacturers on the market. They are made by crushing, the particles have an irregular shape and can scratch the sensitive layer of the photo roll. As a result, printing defects occur and ink consumption increases due to powder spillage from the hopper.

How to refill an HP cartridge yourself

It is impossible to write a single instruction for refueling, since the models are not interchangeable: despite the external similarity, the design is significantly different. Hewlett Packard constantly changes the types of chips, the shape of the side covers (seats), the location of fasteners and technological holes. We will look at the main steps you need to go through when refueling any model.

• Unscrew the screws that hold the sides in place and remove both side pieces.
• The result was two blocks: a paint hopper and a photodrum.

Attention! For many models, the drum does not have a protective cover and is supported only by the sides, so when disassembling it must be held so as not to damage it.

• Remove the photo roller, primary charge roller, cleaning blade (squeegee) and remove any remaining paint from the waste hopper using a vacuum cleaner. If there is none, simply shake out the contents of the container. Clean the squeegee from dirt. If its edge is deformed, install a new blade and sprinkle the edge with a thin layer of toner or special starting powder. Wipe the photo roller and charge shaft with isopropyl alcohol using a lint-free cloth (NeverTab series PCR rollers cannot be wiped). Inspect the photo roll: its surface should be perfectly smooth, without chips, scratches or abrasions. If there are defects, the photo roll needs to be replaced. Lubricate the side shaft holders with fresh conductive grease. Place the cleaned parts in their places and assemble the compartment, securing the photodrum with the side covers.
• Now you need to disassemble the hopper with the coloring powder. Remove the contact group (usually it is attached to a white plate). To do this, unscrew the bar on which the contacts are attached and remove it. Remove the Developer Roller (transfer roller) and dispensing blade.
• Clean the hopper thoroughly to remove any remaining toner. It is ideal to use a vacuum cleaner for this, but be careful not to damage the foam dispenser roller. If there are any defects on it, replace the roller.

The easiest way to clean the hopper is to remove the dosing blade. However, it is difficult to put back on and will require careful adjustment to the correct position, so it can be cleaned without removing the blade. But in this case, removing the remaining powder will take longer.

• Refill with new toner and install the dispensing blade if you removed it. It is important to do this correctly, because the distribution of the powder on the surface of the photo roll depends on the position of the part. If the blade is too high, it does not press well against the photosensitive layer and a colored or black background appears. If the blade is too low, not enough ink reaches the roller and your prints will appear faded. Ideally, for correct installation you need to use a special probe: the blade is screwed on, the probe is placed under it and fixed in the correct position.
• Reinstall the transfer shaft and contact strip, which should also be rubbed with conductive lubricant.
• Rotate the transfer roller to ensure that the toner evenly covers its surface. If this is not the case, the metering blade is not installed correctly.
• Connect the halves of the cartridge so that the spring on one part coincides with the protrusion on the other, screw the side parts.
• Remove the old chip and replace it with a new one, securely fixing it to the case.

Refueling at home: risks and dangers

Chemical toner contains substances harmful to humans, although in minimal doses. It is impossible to get poisoned by them. But, nevertheless, some facts are alarming:

• old laser cartridges should not be thrown into household waste; there are special programs for their recycling;
• Manufacturers of compatible toners do not produce self-refill kits “for dummies”, as they do for inkjet cartridges.

Why? The danger lies in the small size of the particles of the coloring powder. They are ten times smaller than ordinary dust particles, so they settle imperceptibly on the mucous membrane of the eyes and nose, easily penetrate the human body and remain on the surface of the lungs, entering the blood. Due to their microscopic size, the body does not recognize them as a foreign body and does not fight these dangerous substances (benzene, dibutyl, tributyl, organotin compounds, etc.) In Europe, more than a dozen diseases, including cancer, are officially confirmed, the causes of which are ingestion of toner into the body. The first symptoms: headache, fever, cough, and allergic reactions.

Here are a few rules on how to refill an HP cartridge with less risk of harming yourself and others.

• Close windows and doors to prevent air movement. It is a dangerous misconception that you need to work with ink for laser printers in a well-ventilated area! A draft carries particles throughout the room, they are guaranteed to enter the body.
• Pour the powder very carefully, slowly. Use special watering cans. A respirator will not help; it is not designed for such small particles.
• If toner does spill onto your skin or clothing, wash it off with plenty of cold water. It is impossible to collect it with a regular vacuum cleaner; it will only scatter around the room. A vacuum cleaner with a water filter or special disposable bags for a HEPA class household vacuum cleaner (from H-10 to H-14) can help.

Professional refilling of Hewlett Packard cartridges

Probably, 1-2% of users enjoy the process of assembling and disassembling: they need to satisfy the thirst for knowledge “what’s inside?” But if you are not ready to turn your home into a service center with all the necessary tools, and all you care about is the result: a stable printer without much effort, choose professional HP cartridge refills.

A cartridge is a complex mechanism consisting of dozens of small parts. Due to inexperience, if you damage or install one of them incorrectly, you will ruin an expensive printing block or deteriorate the print quality. When you decide to refill an HP printer cartridge yourself, it is important not to miss a single detail. So, if you forget to sprinkle the squeegee with toner, you risk damaging the blade and photo roller. Without lubricating the parts with lubricant or wiping them with acetone, you will end up with a pale print with defects.

Specialized companies have equipment that is not profitable to buy for home refueling. A vacuum cleaner completely removes old toner residues. It is difficult to achieve perfect cleanliness by simply shaking it out of the hopper, and caked lumps of old powder can lead to defects during printing. As already mentioned, it is difficult to install the metering blade without a special feeler gauge.
