惠普打印机678墨盒清零

HP printers use a cartridge monitor system to track ink levels during printing. This system allows the HP printer to keep track of how much ink is left in each cartridge. When the cartridge is empty, the HP printer will display a low ink warning and will refuse to print any further documents until the cartridge is replaced.

When replacing an HP printer cartridge, you can reset the cartridge by pressing and holding the “Power” button for 10 seconds. This will reset the cartridge monitor, allowing the HP printer to recognize the new cartridge. You can also reset the cartridge monitor by running a cartridge cleaning cycle or by pressing and holding the “Cancel” and “Resume” buttons simultaneously for 10 seconds.
