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.
During borderless printing, the ink
was not dry enough before cutting.
Printing may be faint if Print Qual-
ity in Advanced Settings in the
printer driver is set to Standard 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.
(See "Cleaning the Printhead.")
Follow the steps below to remove the jammed piece of paper inside the Top
Cover.
1. Press the Online button to bring the printer offline.
2. Open the Top Cover and make sure the Carriage is not over the Platen.
3. Remove any scraps of paper inside the Top Cover.
(See "Clearing Jammed Roll Paper.")
(See "Clearing a Jammed Sheet.")
4. Close the Top Cover.
Specify a longer drying period in the printer menu, in Roll DryingTime in Pa-
per Details.
(See "Main Menu Settings.")
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.
