Tips on removing the misfed paper
Note the following points in removing the misfed paper.
Remove the misfed paper carefully so as not to tear it.
To avoid tearing the misfed paper, remove the paper slowly with both hands. Using force may tear the paper, making
it more difficult to remove. See also that no pieces of torn paper are left inside the equipment.
When the paper misfeed sign remains after removing the misfed paper:
Depending on the timing of the occurrence, no misfed paper may be found where the paper misfeed sign indicates. If
the sign does not disappear after you have removed the misfed paper, follow the steps as instructed on the touch
panel.
Do not touch the switches, connectors and harnesses inside the equipment.
This could cause a malfunction.
Do not touch the fuser unit or the metal portion around it.
Do not touch the fuser unit or the metal portion around it when you
remove the paper misfed in the right side of the equipment. This could

18 Clearing a Paper Misfeed
If paper misfeeds occur frequently
The following are the common causes of paper misfeeds. If the problem persists, check for the following situations.
An unsuitable original is placed on the DSDF.
Unavailable paper with the equipment is used.
Paper sizes are not consistent between the size in a drawer or the bypass tray and the size registered in the
equipment.
All the misfed paper has not been removed.
There is too much of a gap between the paper and the side or end guide in the drawer.
The amount of paper placed in a drawer exceeds the limit indicated on the side guide of the drawer.
