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 with-
out 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
was cut.
Printing may be faint if Print
Quality in Advanced Settings in
the printer driver is set to Stand-
ard or Draft.

Troubleshooting
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.
1.
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.")
(See "Clearing a Jammed Sheet, Fed Manually.")
3.
Close the Top Cover.
Specify a longer drying period in the Control Panel menu, in Paper Details >
Roll DryingTime.
(See "Menu Settings.")
→P.779
In Advanced Settings of the printer driver, choose Highest or High in Print
Quality.
Printing in Draft or Standard mode is faster and consumes less ink than in
Highest or High modes, but the printing quality is lower.
(See "Giving Priority to Particular Graphic Elements and Colors for Print-
ing.")
