General Customer Support Information
All HP, Canon, Epson, Lexmark and Dell consumer inkjet printers feature some form of a printer self-test or basic
cartridge nozzle test. Most of the HP printer models include a cartridge health electrical test (i.e. ‘Ta p 41′ or ‘Tap
43’). These tests can be used to also verify the printers internal firmware is functioning properly.
The various HP diagnostic tests enclosed in the attachment below can help evaluate general ink cartridge
performance* NOTE: “Non-Genuine”/”Counterfeit” ink alert messages can be bypassed, however if “Incompatible
Print Cartridge / Print Cartridge(s) Problem” / “Refer to printer documentation / “Cartridge Error: Cartridge
must be replaced / “Cartridge in left or right slot is not intended for use in this printer / “Replace Ink Cartridge” /
Ink Cartridge Failure is displayed then the cartridge may be electrically damaged (internal micro-electronics).
Remove and clean ink cartridge (or printhead) electrical contacts. Re-install and re-test printer using the suggested
procedures provided.
