HP Officejet Pro 8600 950/951 Cartridge Protection Option for Compatibles

Update:
We now have a limited stock of New HP950 / HP951 refillable cartridges with ARC available from our website!


When using a compatible Hewlett Packard 950 or HP 951 remanufactured cartridge you may get an error that will prevent you from using it in your machine.  You may need to cancel the cartridge protection feature.
To cancel the cartridge protection feature go to the toolbox where there is a tab named HP Cartridge Protection.  Click on this and then select disable.  The default setting is enable.

You will need to switch off the ink level monitor to allow you to use the refilled cartridge.  In the HP Officejet Pro 8600 go to the printer control panel, click on the right arrow followed by setup.  Select preferences and the cartridge chip information.  For the Officejet Pro 8100 on the control panel press and hold the Wireless and Resume buttons.  The ink supply indicators will blink 4 times.  Then press and hold the Wireless and Resume buttons again which will turn the usage monitor back on.

To reset the ink level (another problem), you will need two extra cartridges plus the one that has been refilled.  Install each cartridge in turn and print an alignment page.  Finally put the new refilled cartridge into the printer and hopefully the ink level will be restored to full.  Another method is to remove the battery from within the side panel of the printer, then replace it a minute or so later.
