Envelopes
This printer prints well on envelopes if you carefully follow these
guidelines:
• Use envelopes made of paper in 75 to 105 g/m
2
(20 to 28 pound)
weight. Printing with envelopes made of paper thinner than this weight
may produce wrinkles thus causing decrease in print quality.
• Be sure to set up the rear stacker (or that of the duplex unit when your
printer has the duplex unit) so that envelopes are ejected straight out the
back to minimize curl.
The capacity of the rear stacker is about 20 sheets.
• Use the envelope sizes shown in the preceding table.
• To avoid damage to the printer, never use envelopes with clasps, snaps,
windows, or synthetic materials.
• Feed from the manual feeder or from the (optional) multi-function
feeder (MFF).
• Feed the envelopes with the gummed side of the flaps facing downward.
• Do not use “encapsulated” adhesives, which seal by pressure alone.
• To avoid jamming, restrict the minimum paper weight to 64 g/m
2
(17
pound).
• To avoid creasing along the edges, use high-quality envelopes with stiff
edges.
• To avoid uneven printing, do not attempt to print on the gummed
overlap areas.
• Be sure to feed or load the envelopes with the envelope centered against
the manual feed slot. Use the guide of the paper sizes.
• Before attempting large-scale printing on envelopes, consult with your
stationery dealer. Also, test the envelopes carefully for consistent,
trouble-free printing.
