Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I'm sorry to hear about your problem. It is familiar to me from previous experience. Often, this problem happens in Kodak photo printers, owing to the failure of a small round plastic part in the printer breaking. The solution is, obviously, to replace that plastic part... but it is not easy to disassemble the printer to the point of removing and replacing the part, then reassembling it is not easy either. It's a considerable job of work, and most people would choose (if the printer is getting old, as is probable) to just replace the printer.
What do you think? would you rather have the printer serviced than repair it yourself, or would you rather replace the printer (not a bad decision *if* the printer is 3 or 4 years old or more... 4 years is a reasonably good lifetime for an inkjet photo printer.) ?
