Ink penetration or corrosion into the nozzle plate will cause a failure of the tiny micro-electronics resulting in a variety of different error messages being displayed. – Cartridge Electrical Failures. Severe HP 64 or 64XL cartridge errors are primarily caused by an electrical breakdown at the cartridge’s nozzle plate. If not, then it is suggested to run the cartridge health diagnostics (‘tap 41’) check or perform a cartridge error bypass (available on select printer models) to confirm that the ink cartridge is damaged. In some cases, errors can be cleared by removing and cleaning the ink cartridges and printer flex cable contacts. In addition, the power light may be blinking while the error message is displayed. – Severe Errors. When a HP 64 or HP 64XL ink cartridge has poor connectivity (between contacts and flex cable inside printer) or is suffering from marginal internal micro-electrical performance, you may observe error messages such as ‘incompatible cartridges’, ‘print cartridges error’, ‘cartridge missing or not detected’, ‘refer to documentation’, ‘cartridge in left/right slot is missing’, etc.

A message that says “Cartridge Missing or Not Detected”, “Incompatible Print Cartridge”, “Black/Color Cartridge Problem”, “Refer to printer documentation”, “Cartridge in Left/Right slot is not intended for use in this printer”, or similar, on your monitor or on the printer display.Blinking cartridge lights on the printer.If the problem persists then return cartridge to your refiller for analysis. First remove and thoroughly clean cartridges electrical contacts & printer flex cable contacts and retest (refer to Printer Maintenance). If a “Non-HP Cartridge(s)” or “Very Low on Ink”, or similar message cannot be bypassed then the cartridge may be suffering from marginal internal electrical performance and may need to be replaced with a new one. HP 64 / 64XL Low Ink, Depleted, Ink Out & Empty Error Messagesįollowing the installation of a refilled ink cartridge, nuisance or annoyance messages will typically be displayed after the initial ‘low ink’ or ‘non-genuine’ ink messages. NOTE:“ Empty”, “ Low Ink”, “ Depleted“, “ Out of Ink“, “ ? Marks“, “ Counterfeit” and “ Non-Genuine Cartridge” alerts are COMPLETELY NORMAL for all HP 64 & HP 64XL black and color ink cartridges which have been refilled! While at first this may be an unusual workflow, it does allow print operations to proceed.
