out ink tanks installed for some
time, ink has become clogged in
the ink supply system.
Paper is jammed inside the Top

Printing is faint
> Problems with the printing quality
Cause
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 Cov-
er.
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.
3. Close the Top Cover.
Specify a longer drying period in the Control Panel menu, in Paper Details >
Roll DryingTime.
(See "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.
