Letterhead Refer to the illustrations at left to orient A4 or letter size
preprinted paper in the multipurpose feeder or the paper
trays.
Preprinted papers such as letterhead must be able to with-
stand temperatures up to 195°C (383°F) without melting
or releasing hazardous emissions. Use inks that are not
affected by the resin in toner or the silicone in the fuser.
Inks that are oxidation-set or oil-based should meet these
requirements. Latex inks might not.
