Printing on Special Paper
In addition to printing on single sheets and continuous paper, your
printer can print on a wide variety of other paper types, such as
envelopes, labels, and multi-part forms. Before printing on special
types of paper, you need to change the paper-thickness setting.
CAUTION:
l
When printing on labels or multi-part forms, make
sure that your application program settings keep the
printing entirely within the printable area.
l
Always return the paper-thickness lever to position 0
when you return to printing on ordinary paper.
Paper-thickness lever
Set the paper-thickness lever to match the thickness of your paper
