I hae a HP 4500 wireless printer scanner copier which has worked as a printer and a copier for several months now. (never as a scanner).  About a month ago the BLACK cartridge went dry and I refilled.  However, the printer would not accept the cartridge after that so I bought a replacement cartridge (not a HP) ebay and used it successfully for a few weeks.  Then, yesterday, I had a paper jam.  After I removed the paper, the rinter would not accept the substitute cartridge that I had put in..     LAST night I shut the system down.  This AM I fired it up again, the printer went through the "new cartridge" procecedure, printed out one document, then went right back into the "incompatible cartrdge" modeandrefused to PRINT.   I am hesitnt to buy another cartridge as I feel that it won't accept that  either.
Any ideas? ? ?   
Thanks for looking,  JIMIs there any SPECIFIC reason why you have found it necessary to post this issue in 2 forums on the same topic? truenorth

 Now i see your 2 posts are in the same forum --one above the other.  TRUENORTH:   Well, I thot the un-install PROBLEM was software and the refusal to accept the ink cartridge was hardware.  Please excuse my error and chalk it up to ignorance.no problem--let's see if we can get it printing for you.truenorthIn future there's no need to create multiple Posts for the same issue.
