190 8 Troubleshooting and Maintenance EN
When printing on
both sides of the
page, the print
quality is reduced,
pages curl, or
duplexing results in
incorrect or
multiple page
feeds. When you print on both sides, there will be
a difference in the way the product
performs. You may also experience
incorrect or multiple feeds. Instead of duplexing manually, use the
Layout (Pages-per-Sheet or N-Up) feature
in the program from which you are
printing, if available. See the program’s
documentation for information.
Allow sheet to cool and flatten before
printing the second side.
Make sure the leading edge of sheets are
not bent or curled.
To minimize curl, set the paper path lever
to the lower position (for front paper output
slot. This allows a straight-through paper
path.
If all printed pages are printing with poor
quality, frequent duplexing might be the
cause. See “Using a cleaning page” on
page 219.
