Printing onto envelopes
● Do not use envelopes that have metal clasps, plastic snaps, string closures, windows, linings, self-adhesive
patches or synthetic materials. Attempting to print on these may cause misfeeds, inadequate toner adherence or
other trouble.
● Creases or smudging may occur. This is especially true of embossed surfaces and other irregular surfaces.
● Under high humidity and temperature conditions the glue flaps on some envelopes may become sticky and be
sealed closed when printed.
● Use only envelopes which are flat and crisply folded. Curled or poorly formed envelopes may be poorly printed or
may cause misfeeds.
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.
1
Unlatch the duplex module and slide it to
the left.
Unlatch the module and
gently move the module
away from the machine.
If the machine is not
equipped with a duplex
module, open the side
cover similarly.
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.
NOTE
Be sure to return the lever to the normal position when finished feeding envelopes. If not, inadequate toner
adherence, paper misfeeds or other trouble may occur.
