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 become clogged in the ink
supply system.
Paper is jammed inside the Top
Cover.
The ink was not dry when paper
934
was 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.")
To check for nozzles after printing, set Frequency in Nozzle Check in the Control Panel menu to a set-
ting 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.")
