My MP610 gave me U052 error today. U052: The type of print head is incorrect. Install the correct print head. MP610 and iP4500 uses the same printhead. I have backup iP4500 printers. Is it safe to put a good printhead into the MP610 with U052 error? I think it is safe because the hardware is sane enough to generate this error. Do you agree with my assessment?
