Solving Problems with Printing Quality
Solution
Remove the moist media and replace it
with new, dry media.

cards, thick stock, or transparencies,
specify the appropriate media type in
the printer driver.
Remove the toner cartridge and check
for damage. If it is damaged, replace it.
Before printing media other than
envelopes, be sure to lower the lever
on the fuser unit.
Clean the media transfer roller.
If you think the transfer roller should be
replaced, contact Technical Support
with the error information.
Print several blank sheets and the
excess toner should disappear.
