Popular laser printers have one drawback - the price of cartridges is painfully affordable. In order not to buy a new cartridge for a printer with laser imaging technology, you can refill the existing one. However, the manufacturer often puts a special chip in the cartridge that blocks the ability to print after the printer has issued a certain number of finished pages.
Instructions
Step 1
To unlock the cartridge, you will need a chip programmer for cartridges. You can buy it in stores with computer equipment or spare parts for copiers. The programmer should be selected suitable for a specific cartridge, because universal models may not be suitable. There are programmers with interchangeable nozzles - a handy thing for those who need to work with different printers.
Step 2
The next step is to read the instructions for the device, as they may differ depending on the type of programmer. Some models work when connected to a computer, in which case you will have to install a working program and drivers on it. Standalone programming devices do not require a PC connection, and the chip zeroing process is controlled by several buttons on the device itself.
Step 3
Next, open the printer and remove the cartridge from it. This should be done with the device turned on, otherwise some copiers may give an error and you will have to reset the chip again. Then remove the chip from the cartridge. This process is different for each type of cartridge. Sometimes you have to cut the plastic case to extract the spare part - in such cases it is easier to buy an adapter for the programmer.
Step 4
The released chip is connected to the socket of the programmer. Zeroing takes place following the instructions for the device. After that, the unlocked chip is inserted back into place, and the cartridge is returned to the printer.
