Printing is faint
Printing is faint
Cause
You may be printing on the
wrong side of the paper.
The Printhead nozzles are clog-
ged.
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 driver is set to
Standard or Fast.
User's Guide
Print on the printing surface.
Print a test pattern to check the nozzles and see if they are clogged.
(See "Checking for Nozzle Clogging.")
To check for nozzles after printing, set Frequency in Nozzle Check in the Control Panel menu to
a setting other than Off.
Furthermore, to have a warning displayed depending on the result of the nozzle check, set
Warning in Nozzle Check in the Control Panel menu to On.
Note that when Warning is set to On, printing may stop depending on the content of the warning.
(See "Menu Settings.")

➔
In Advanced Settings of the printer driver, choose Highest quality or High in Print Quality.
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.
