The Printhead nozzles are clogged.
Because the printer was left without ink
tanks installed for some time, ink has
become clogged in the ink supply sys-
tem.
Paper is jammed inside the Top Cover.
The ink was not dry when paper was
cut.
Printing may be faint if Print Quality in
Advanced Settings in the printer driv-
er is set to Standard or Fast.
You are printing on paper that tends to
generate dust when cut.
