replace the

- sheet feeder unit, or

- photo paper tray.

No printing, or no color ejected. Replace the

- ink tank,

- print head

- logic board ass’y

, or

- purge unit. Printing is faint, or white lines appear on printouts even after print head cleaning. Line(s) not included in the print data appears on printouts.

Remove and re-install the print head, or replace the

- ink tank,

- print head

- purge unit, or
