Printing is faint Printing is faint
Cause
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 be-
come clogged in the ink supply system.
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 driver is
set to Standard or Fast.
You are printing on paper that tends to
generate dust when cut.

Print on the printing surface.
Print a test pattern to check the nozzles and see if they are clogged.
(See "Checking for Nozzle Clogging.")
After the ink tanks have been installed for 24 hours, run Head Cleaning B from the Control Panel.
(See "Cleaning the Printhead.")
Follow the steps below to remove the jammed piece of paper inside the Top Cover.

Open the Top Cover and make sure the Carriage is not over the Platen.
2.
Remove any scraps of paper inside the Top Cover.
(See "Clearing Jammed Roll Paper.")

Printing in Fast or Standard mode is faster and consumes less ink than in Highest quality or
High modes, but the printing quality is lower.
(See "Giving Priority to Particular Graphic Elements and Colors for Printing.")
In the Control Panel menu, set CutDustReduct. in Paper Details to On.
