Sorry -- This is a known defect by Canon and your printer is most likely headed for the trash heap. Please refer to the subject “Call to Arms for the dreaded U052 Wrong Printhead Error” that’s also listed under Personal Printers in the Canon Forum. The fact that there are over 11,000 views gives you some sense of the magnitude of the issue.

In response to the question raised by drazdik about just buying a new printhead, a new printhead costs about the same as a new printer. Furthermore, many folks have indicated a new printhead did not resolve the issue. Below is the verbatim response I received from Canon Support (ticket #1583267). Your decision should be an easy one – buy a new printer you’d be happy with from a company that will stand behind their products.
