I have a HP Deskjet 400 and it worked great till...
One day I went to print and the ink cartridge slid to the center position and the ink cartridge change light was blinking. What I just described is exactly what happens when you push the ink cartridge change button and the cartridge slides to the center position and waits while the light on top blinks. It had a non-empty cartridge in it when this happens. I shelved it and used a backup Deskjet 500 from my office (uses the same cartridge). THe Deskjet 400 sat for about 4 months till I installed it on a new PC last week (used latest driver from HP). It still has the same problem. It bahaves normally (makes noise at PC startup and shutdown) till you go to print. Last week I was using a new ink cartridge (different one from the discovery of the problem) when the printer duplicated the problem. What's going on?? Is it still good??
Thanks in advance,
