Clean the inside of the auto-duplex unit After extensive printing, ink might be deposited on the inside of the auto-duplex unit causing ink to smear when printing on both sides of the paper. To remove the deposited ink, use a lint free cloth to clean the inside of the auto-duplex unit. Enable the printer's output ramp When printing in Fast Normal (default) or Fast print mode, the printer does not use the output ramp to hold each printed page before releasing it onto the output tray. If the printer starts printing the next page while the printed page is still drying on the output tray, the newly printed page might rub against the printed page on the output tray, causing ink to smear. Severity of smearing depends on the amount of ink used on each printed page. To prevent the printed pages from rubbing against each other, print using the Normal or Best print mode. Alternatively, enable the OUTPUT RAMP EXTENSION on the printer control panel. See Paper Handling menu.

Clean the inside of the auto-duplex unit
After extensive printing, ink might be deposited on the inside of the auto-duplex unit
causing ink to smear when printing on both sides of the paper. To remove the deposited
ink, use a lint free cloth to clean the inside of the auto-duplex unit.
Enable the printer's output ramp
When printing in
Fast Normal
(default) or
Fast
print mode, the printer does not use the
output ramp to hold each printed page before releasing it onto the output tray. If the printer
starts printing the next page while the printed page is still drying on the output tray, the
newly printed page might rub against the printed page on the output tray, causing ink to
smear. Severity of smearing depends on the amount of ink used on each printed page.
To prevent the printed pages from rubbing against each other, print using the
Normal
or
Best
print mode. Alternatively, enable the
OUTPUT RAMP EXTENSION
on the printer
control panel. See
