The equipment starts the warm-up. Follow the guidance on the touch panel.
Tips on removing the jammed paper
Note the following points in removing the jammed paper.
TROUBLESHOOTING FOR THE HARDWARE
Remove the jammed paper carefully so as not to tear it.
To avoid tearing the jammed 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 jam sign remains after removing the jammed paper:
Depending on the timing of the occurrence, no jammed paper may be found where the paper jam sign indicates. If the
sign does not disappear after you have removed the jammed paper, follow the steps as instructed on the touch panel.
Do not touch the connectors 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 jammed in the right side of the equipment. This could
burn you or the shock could cause you to get your hand injured in the
machine.
Do not touch the transfer belt.
When you remove the paper jammed in the right side of the equipment,
be sure not to touch the transfer belt. This could stain copy images.
Clearing a Paper Jam 19
1.TROUBLESHOOTING FOR THE HARDWARE
If paper jams occur frequently
The following are the common causes of paper jams. If the problem persists, check for the following situations.
An unsuitable original is placed on the ADF.
Unavailable paper with the equipment is used.
Paper sizes are not consistent between the size in a tray or the MPT and the size registered in the equipment.
All the jammed paper has not been removed.
There is too much of a gap between the paper and the side or end guide in the tray.
The amount of paper placed in a tray exceeds the limit indicated on the side guide of the tray.
