Pressing the Resume/Cancel button will exit the error, and enable printing. In repair servicing, replace the bottom case unit (QM2-

1583), or the ink absorbers (QC1-5381 / 5382 / 5383 / 5384 / 5385 / 5386 / 5387 / 5388 / 5389 / 5390).

After removing the cable between the camera and the printer, press the Resume/Cancel button, and re-connect the cable.

Press the Resume/Cancel button to eject the paper being used at error occurrence. Printing will resume from on the front side of the next page.

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).

- Protect the paper output slot from exposure to excessive light.

The service call error, indicating the waste ink absorber is full, is likely to occur soon.

Data which was to be printed on the back side of paper at error occurrence is skipped (not printed).
