2.6.5. PAPER JAMS
The paper could jam along its path inside the machine.
Jamming could be caused by one of the following:

－ Stapled paper or with paper clips (this can seriously damage the
machine)
－ Multicopy forms where the sheets are poorly glued together.
The areas where jams are more likely to occur are:
－ front document feed slot
－ inside the printer
－ rear document output slot
