Printing on envelopes (Face up printing)
Use of any of the envelopes listed below may cause damage to the printer. Such damage is
not covered under any warranty or service agreement.
•
Envelopes that are damaged, curled, wrinkled, or irregularly shaped
•
Envelopes that are extremely shiny or highly textured
•
Envelopes with clasps, snaps or tie strings
•
Envelopes with self-adhesive closures
•
Envelopes of baggy construction
•
Envelopes that are not sharply creased
•
Embossed envelopes
•
Envelopes that were previously printed by a laser printer
•
Envelopes that are pre-printed on the inside
•
Envelopes that cannot be arranged uniformly when placed in a pile
•
Envelopes constructed with paper that exceeds the paper weight specifications for the
printer.
•
Poorly manufactured envelopes with edges that are not straight or consistently square.
•
Envelopes with transparent windows, holes, cutouts or perforations.
NOTE:
•
Before printing envelopes, fan the stack well to avoid paper jams and misfeeds.
•
Do not load different types of paper at the same time in the paper tray because it may
cause paper jams or misfeeds.
•
Do not print envelopes using duplex printing.
•
If the application software does not support paper size selection in its print menu, you can
change the paper size on the printers control panel under the
PAPER
menu. For more
information, see
subsection 5. CONTROL PANEL OPERATION in this Chapter
