Printing is faint

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 sys-
tem.
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 Standard or Draft.
You are printing on paper that tends to
generate dust when cut.

Paper rubs against the printhead

Paper rubs against the printhead
Cause
The type of paper specified in the printer
driver does not match the type loaded in
the printer.
Basic Guide
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.")
→User's Guide
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.")
In the Control Panel menu, set CutDustReduct. in Paper Details to On.
(See "Reducing Dust from Cutting Rolls.")
Load paper of the same type as you have specified in the printer driver.
(See "Loading Rolls in the Printer.")
(See "Loading Sheets in the Feed Slot.")
