D. If the cartridge chip has been replaced/reprogrammed (i.e. a 2nd time), then this ink cartridge alert
may be a printer defect and not a cartridge issue. It is suggested to reset the printer by:
1) Printers with 1-9 keypad
a. Unplug the power cable from the back of printer.
b. Hold down number 9 & # keys, plug in the power and turn the printer on.
c. The printer will reset itself.
2) Printers without 1-9 keypad:
a. Turn off the HP All-in-One by pressing the On button.
b. Unplug the power cord from the back of the HP All-in-One.
c. Plug the power cord back into the HP All-in-One.
d. Turn on the HP All-in-One by pressing the On button.
e. Check the printer for the error message. If the error message still displays, go to the n ext step.
E. If an error condition persists then we suggest that you thoroughly review the steps outlined on our HP
02 support page: http://inkjet411.com/?page_id=35
F. Refer to the HP Printer Diagnostic’s document (PDF file) at the following link for more advanced
diagnostic tests for your specific printer model: http://inkjet411.com/?page_id=1813
G. If the PRINTHEAD is ok (pending the results of the ‘Tap 43’ test performed above) and this still does
not provide clarity to the issue or remedy the problem, then you may need to replace the suspect ink
cartridge(s) with a brand new HP ink cartridge to rule out the cartridge/chip as a contributing variable.
*The HP 02 ink-series printer models have an electronic PRINTHEAD within the base of the carriage
assembly (responsible for pulling ink from the 4 ink cartridges and then firing the ink droplets onto the
paper) – the HP 02 PRINTHEAD typically has a maximum life of approximately 30,000 pages (~15,000
page average). Unfortunately, the permanent PRINTHEAD is not replaceable - here is how it functions:
