Install the print head properly, and close the front cover. Or, with the print head installed, turn the printer off and on. Set the CD-R tray and tray feeder properly, and press the Resume button. Remove the CD-R tray feeder, and press the Resume button.

set the tray in the tray feeder, and press the Resume button. Pressing the Resume button will exit the error, and enable printing. In repair servicing, replace the bottom case unit (QM2-0663), or 5-item set of the ink absorbers (QC1-2232/2233/2234/2235/2236). After removing the cable between the camera and the printer, press the Resume button, and re-connect the cable.

Press the Resume button, and after confirming the following, perform print head alignment again:

- Set an appropriate type and size of paper (plain paper, A4 or letter).

- Check that the nozzle check pattern is properly printed (all ink ejected, no faint printing)

- Check that the paper output slot is not exposed to light.

Pressing the Resume button will exit the error without ink tank replacement, however, ink may run out during printing.
