System Ink Failure in a Deskjet 6500

By Dan Wonder

The HP Deskjet 6500 is an all-in-one color inkjet printer series that Hewlett-Packard introduced in 2009. Designed for business or office use, the medium-sized device comes with printing, copying, scanning and fax capabilities. Some HP 6500 printers may experience ink system failure, which is displayed on the control panel as “Ink System Failure” or any of five dozen “0x..." codes.

Reset Printer

In some cases, simply turning off the Deskjet 6500 and turning it on again will get rid of the error message. First, disconnect the power cord from the back of the printer, then unplug the power cord from the wall socket. Wait at least 15 seconds before reconnecting the printer. If the printer does not turn on by itself, press the Power button.

Clean Printhead

If there is still an ink system failure or error message, you may want to check the printhead. Sometimes the printhead may be installed incorrectly, or have ink or debris on its electrical contacts. Make sure the power is on, then open the ink cartridge access door, remove all the cartridges and remove the printhead. You will see the three areas of the printhead that need to be cleaned. They are the plastic ramps flanking the ink nozzles, the electrical contacts, and the edge between the ink nozzles and the electrical contacts. Clean all areas using clean, lint-free cloth lightly dampened with distilled or bottled water. Reinstall the printhead and the cartridges, then close the cartridge access door.

Replace Printhead

If cleaning the printhead doesn’t solve the problem, replace it. Contact HP Support to obtain a replacement. If the replacement is done under warranty, HP will send you a new printhead, cleaning materials and a full set of new ink cartridges. If your printhead is no longer under warranty, you can purchase a new one at the HP Parts online store. Since the HP 6500 uses four ink cartridges, type "CN643A" (omitting quotes) in the Search box to find the printhead, then follow the online instructions to order it.

Service Printer

If you have followed all aforementioned troubleshooting and there is still an ink system failure, service the printer. If your product is under warranty, contact HP. If not, go to the HP Out of Warranty Support Options page (see Resources).
