Hi Vf32,

Please try the following to resolve the issue:

Remove the Ink Tanks

Confirm that the printer is powered on.
Pull open the paper output tray.
Lift the scanning unit (printer cover) with both hands and set the scanning unit support. (The print head will move to the replacement position.)

Note: When the scanning unit (printer cover) is opened more than ten minutes, the print head moves to the right side. If this occurs, close the scanning unit (printer cover), and open it again.
Remove the ink tanks by pressing the tab of each tank.

Caution: Handle the ink tanks with care so that your clothes and surrounding area do not get soiled. Make sure to remove the ink tanks one by one.

Reseating the Print Head

Raise the print head lock lever then lower it again to reseat the print head. If removing the print head to replace with a new print head, proceed to step 2.
Tilt the print head slightly towards the front of the machine and lift out gently.

Hi karl1, Thank you for sending the visual instructions to solve the "type of print head is incorrect..." problem. By the way the LCD screen with the error message had "U052" on it, if that is any help. I think I followed the instructions correctly, but the same message comes up again and nothing prints. I should also tell you that I before the problem occurred I tried to update to the latest driver for the MP520, if that is any help.

Thanks, vf32

Hi vf32,

Since reseating the print head did not resolve the issue, I would recommend using the Contact Us link to get in touch with our support staff as it would appear that the unit would require service. They can inform you of any available service options.
