When you have refilled your cartridge, your job have not fully completed yet. Some printers fail to work and claim that your cartridge is still empty, even though it’s full after you refill the cartridge.

The printer has its memory and remember the last cartridge you use. There are two ways to overcome this problem. First is to reset the ink level of the cartridge as shown below, second is to use 2 spare cartridges. Note: These procedure may not work for some printers. The printer simply refuse to print alignment page when you cover the contact with tape.

tapi biasalah HP, baru refill 3-4 kali terus kong katrij.
