are smudged with ink.
Larger size of paper than the original
was placed on the Paper Feed Tray
at the time of the master-making
process.
Because a master was made according to
a larger size than the original, the edges of
the original were processed as shadows.
Set the same size of paper as the original
and perform the master-making operation
again. Or attach tape as described below
to solve the problem.
Did you use
[Max. Scan]
setting
when making the master?
When printing thick paper such as
cards, corners of the paper contacted
and damaged the master.
Make another master and print with the
new master. Or pull out the Print Drum
(Cylinder) and attach cellophane tape to
the damaged section on the master.
However, if attached with cellophane tape,
a master may not been properly sent to
the Master Disposal Box.
