Fusing unit pressure adjusting levers
When feeding envelopes from the multi-
purpose drawer, damage to the envelopes or
smudges on prints may occur even if envelopes
within specification are used. In this case, the
problem may be reduced by shifting the fusing
unit pressure adjusting levers from the normal
position to the lower pressure position. Follow
the procedure below.
Be sure to return the lever to the normal
position when finished feeding envelopes. If
not, inadequate toner adherence, paper
misfeeds or other problems may occur.
1. Unlatch the duplex module and slide it to
the left. If the machine is not equipped
with a duplex module, open the side cover
to gain access.
2. Lower the two fusing unit pressure
adjusting levers marked A and B in the
illustration.
3. Gently close the duplex module. If the
machine is not equipped with a duplex
module, close the side cover.
