3.1.4 Labels
You must use the tractor as a pull tractor to print on labels. Keep these tips in mind:
1. You load labels the same way you load tractor paper, except that thegap adjust lever should be
set to 1.
3. Because labels are especially sensitive to temperature and humidity, use them only under normal
operating conditions.
4. Make sure the printing stays entirely within the printable area. (See the Appendix for
specifications.)
5. Do not leave labels loaded in the printer between jobs; they curl around the platen and may jam
when you resume printing.
6. Remove the labels from the printer, tear off the fresh supply at the rear of the printer; then press
LF/FF
to advance the remaining labels out of the printer.
Caution: Never feed labels backward through the printer; they can easily peel off the backing
and jam the printer. If a label does become stuck in the printer, contact your dealer.
3.1.5 Envelopes
The way of installing envelopes is the same of cut-sheet. Keep the following tips in mind.
1. Before loading an envelope, set the gap adjust lever to position 4 or 5.
2. To load an envelope, push it firmly and hold it until it feeds into the printer.
3. Use envelopes only under normal temperature and humidity conditions.
4. Make sure the printing stays entirely within the printable area. The print head must not go past the
left or right edge of the envelope or other thick paper. (See the Appendix for specifications.) It’s a
good idea to print a test sample using a normal single sheet of paper before you print on the
envelopes.
