Printing on Special Paper
Envelopes
You can load envelopes from the top just like single-sheet paper.
However, you should pay attention to the special considerations
below:
l
Always set the paper-thickness lever to position 2, 3, or 4
depending on the thickness of the envelope.
l
Always feed envelopes by inserting the wide edge into the
printer.
CAUTION:
l
Only use envelopes under normal operating conditions.
l
Printing on the edge of an envelope can damage the
print head. Make sure the printing stays entirely
within the printable area of the envelopes. (See page
7-5.)
