I have used the recycled ink cartridges for a number of years but now one of the cartridges will not work. I'm connected via USB and use Windows 10. In the past, I would go to Settings...HP cartridge protection..."Disable" option and save the settings.My Printer Assistant is now missing as well. I cleaned the printheads a number of times and even changed the cartridge. I was told to perform a power drain. "1) Take out the cartridges 2) Unplug the power cord from the printer & wall. 3) Press and hold the power button down for 15 seconds and release the power button, wait for about 30 seconds. 4) Plug the power cord back into the printer and wall, ensure the printer is plugged into the wall & not into a surge protector. 5) Insert the cartridges back into the printer." Still no ink. The other 3 cartridges work fine. I was thinking that I should just delete the HP from my PC and reinstall. Would appreciate receiving your comments.
