I have a PIXMA MX892 personal printer. Error U052 type of print head is incorrect

[granny]

How do I resolve the 052 error  It appeared initially with the red light blinking as if the cartridge needed to be replaced ... there is a new cli-226BK cartridge in place now. The blinking light is now steady; however, the 052 error code appears and I'm unable to print.

Hi granny,

To try and resolve the error, please remove and reseat all of the ink tanks and print head in the printer, then turn off the printer, unplug the power cord and leave it out for at least 10 minutes, then plug it back in and turn it back on.  If the error persists, the printer will require servicing; please call or email us at one of the methods on the Contact Us page to obtain your servicing options.
