Solution
Before printing on special paper, check
its surface carefully. Printing on non-print
surfaces reduces print quality and can
damage the machine's internal
components. See "Recommended
Paper Sizes and Types" and "Unusable
Paper", About This Machine
Use manufacturer-genuine toner.
Contact your service representative.
Check the application supports the
printer driver.
Use the machine's printer driver and
check the machine is the designated
printer. See "Setting Up the Printer
Driver", Printer Reference
Check whether there is failed or
cancelled data remaining. See
"Checking the Error Log", Printer
Reference .
Printing on recommended paper
produces better resolution. See
"Recommended Paper Sizes and
Types", About This Machine
If the Data In indicator is blinking, data
is being processed. Simply wait until
printing resumes.
To resume from Energy Saver mode, it
has to warm up, and this takes time. See
"ENERGY STAR Program", About This
Machine .
