All 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. ‘Tap 41’ / ‘Tap 43’). These internal diagnostic tests can also be used to verify the printer’s internal firmware is functioning properly. Refer to PDF attachment below for instructions on your HP printer model.

The various HP diagnostic tests enclosed in the attachment above 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.

Ink Refill Center Locations: 

 

NOTE: If you need to purchase a new ink cartridge(s) due to a cartridge failure or because a refill center is not conveniently located near you and you would like to cut ink costs, we suggest you try a remanufactured ink cartridge from http://www.inkplicity.com/  Their ink cartridges typically have the lowest cost in the USA, have a high reliability rating, come with a 1-year warranty and provide free shipping for all orders above $20 (purchases available to USA residents only).
