Printer cartridge repair

The cartridges that come with modern printer models are quite reliable and high-quality devices. Compliance with the rules of their use guarantees proper operation for a long time. But the likelihood of failure cannot be completely ruled out either. In such situations, the owner of office equipment has a choice: take the faulty cartridge to the service or try to solve the problem on his own.

The most common printer cartridge problems include:

• drying on printheads of ink;
• failure of the photo vault;
• squeegee breakage.

The first problem is most often encountered by owners of inkjet printers. It is solved quite simply: to dissolve the paint, a little alcohol is poured into the saucer (vodka can be used) and the cartridge is lowered into the liquid with its head down.

After 2 hours, you need to take an empty syringe and pull back the plunger. The medical instrument should be inserted into the dye injection port and, by pulling the plunger sharply, clean the print head. Refilled cartridges are installed in place by selecting the cleaning mode in the settings. Cleaning needs to be done several times, then try to print. If there is a problem, the technique is reset and then tried again. If there is such a need, then the purification is repeated.

Repairing this print part of a laser printer is more difficult to handle. The first step is to determine the nature of the malfunction. If the cartridge is functional and has enough ink, but blots and streaks form at the time of printing, then the case is most likely a drum unit or squeegee. The latter removes excess toner from the light-sensitive drum.

Repair of the printer cartridge, requiring replacement of the photo tube, can be done by hand. Almost all office equipment users can cope with this task. To replace the drum, you must first remove the cartridge from the machine. Push out the pins holding the parts together. After that, separate the parts of the consumable and unscrew the fasteners on the cover to remove it. Pull out the sleeve holding the photosensitive drum, rotate it and remove it from the axle.

Install a new part to replace the broken one. After that, the cartridge must be reassembled in the reverse order. It is better to do this in a room where there is no bright light, otherwise you can expose a new detail. Rebuilding the cartridge by replacing the photo roller is a great alternative to purchasing a new consumable.

If the problem lies in the squeegee, which is a plastic plate, then this element can also be changed independently. The breakage of this part is indicated by long stripes appearing on the printed sheets.

This happens when the plate is worn or broken. To replace the squeegee, unscrew the screw on one side of the cartridge, remove the side cover. Slide the section containing the shaft and divide the consumable in two. Lift the photosensitive drum and remove it by turning it slightly. Pull this element out and place it in a dark place. To dismantle the squeegee, unscrew the 2 screws, and then install the same part in its place. Screw in the screws, put the drum in place.

It is advisable to change the squeegee and light-sensitive drum at the same time. Samsung printers do not have a plastic plate, so this usually requires replacing the metering blade. The magnetic shaft breaks in very rare cases. Disassemble the cartridge carefully. Try to remember the location of each element - this will simplify the assembly. Do not forget that the photo roll is sensitive to bright light, do not remove it from the package earlier than necessary. Install the drum into the cartridge quickly under dim lighting. This part requires careful handling, otherwise scratches will appear on its surface.

After installing the repaired cartridge, test its operation. The first pages printed may have blots, but later print quality improves. And although the cartridges in different modifications of printers are different, their design is similar, therefore, the principles of repair are identical.
