1. Clean all the contacts.
2. If item one fails, I see if the printer is over 2 years old.
3. If it's over 2 years old I get rid of it.
Why I list item 3 is that here they charge to dispose of that busted gear. I can save myself some bucks by "giving" it away.
I "inherited" an HP 5300 All-in-One. The little screen said "Cannot read tricolor cartridge", so I replaced the cartridge, thinking it was empty or defective. It still says the same thing with the new cartridge. What can I do to troubleshoot the printer and fix this?
