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.845
Because the printer was left without ink
tanks installed for some time, ink has be-
come clogged in the ink supply system.
After the ink tanks have been installed for 24 hours, run Head Cleaning B from the Control Panel.
(See "Cleaning the Printhead.") →P.846
Paper is jammed inside the Top Cover. 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.") →P.881

Printing may be faint if Print Quality 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.
(See "Giving Priority to Particular Graphic Elements and Colors for Printing.") →P.61
You are printing on paper that tends to
generate dust when cut.
In the Control Panel menu, set CutDustReduct. in Paper Details to On.
