Problems with the printing quality

Printing is faint

You may be printing on the wrong side of the paper.
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 system.
Paper is jammed inside the Top Cover.
During borderless printing, the ink was not dry
enough before cutting.
Printing may be faint if Print Quality in Advanced
Settings in the printer driver is set to Standard or
Draft.
