Printing is faint
Cause Corrective Action
You may be printing on the wrong
side of the paper.
Print on the printing surface.
The Printhead nozzles are clogged. Print a test pattern to check the nozzles and see if they are clogged.
(See "Checking for Nozzle Clogging.") →P.817
Because the printer was left without
ink tanks installed for some time,
ink has become clogged in the ink
supply system.
After the ink tanks have been installed for 24 hours, run Head Cleaning B.
(See "Cleaning the Printhead.") →P.819
Paper is jammed inside the Top
Cover.
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.") →P.852
(See "Clearing a Jammed Sheet.") →P.856
4. Close the Top Cover.
During borderless printing, the ink
was not dry enough before cutting.
Specify a longer drying period in the printer menu, in Roll DryingTime in Pa-
per Details.
(See "Main Menu Settings.") →P.722
Printing may be faint if Print Qual-
ity in Advanced Settings in the
printer driver is set to Standard or
Draft.
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.
