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.

damaged section on the master. However,
if attached with cellophane tape, a master
may not been properly sent to the Master
Disposal Box.

not fit to the width of paper at the time
of the master-making process.
Adjust the Feed Tray Paper Guides to the
width of the paper.
If the Feed Tray Paper Guides are set
wider than the width of the paper, a master
will become wider than necessary.
