Solution
For Booklet Left Binding and Booklet
Right Binding, choose Collate only in
the printer driver's Basic Tab. Do not
set collation in the application.
Place the machine on a flat, hard, level
surface.
Remove the tray that you are printing
from and reinsert it completely into the
machine.
Turn off the machine and remove the
object. If you cannot remove it, contact
Technical Support.
If a band appears in the copy after
copying, select a copy density setting
that is one level darker.
If a band appears in the image after
scanning, scan using the original
glass.
Place the document on the original
glass. With the Envelope DL size,
some areas may not be copied.
If the image becomes lighter or darker,
scan using the original glass. In addi-
tion, perform the scan operation after
turning the machine on and lighting the
lamp for an hour and a half or more.
Set the scan mode to PHOTO.
