Printing Onto Envelopes; Fusing Unit Pressure Adjusting Levers - Sharp AR-M451N Operation Manual

Printing onto envelopes

G 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.
G Creases or smudging may occur. This is especially true of embossed surfaces and other irregular surfaces.
G Under high humidity and temperature conditions the glue flaps on some envelopes may become sticky and be
sealed closed when printed.
G 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.
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.
