2.2 Adhesive-Backed Labels

The basic rule for printing on adhesive labels is that the adhesive
must never come into contact with any part of the printer. Adhe-
sive paper sticking to the drum or rollers will damage the printer.
Label paper must be manually fed.
Label paper has a structure comprised of three layers, as shown
in the figure below. The top sheet is printed on. The adhesive
layer consists of pressure-sensitive adhesives. The carrier sheet
(also called the linear or backing sheet) holds the labels until
use. Due to the complexity of its composition, adhesive-backed
label paper is particularly likely to give trouble in printing.
Adhesive label paper must be entirely covered by its top sheet,
with no spaces between the individual labels. Labels with spaces
in between are apt to peel off, causing serious paper jam prob-
lems.
Some label paper is manufactured with an extra margin of top
sheet around the edge. Do not remove the extra top sheet from
the carrier sheet until after printing is finished.

Envelopes
The printer can print on envelopes using paper with a basis

weight of 60 to 79 g/m (16 to 21 lb/ream). Envelopes must be
manually fed.
An envelope is a more complex object than a single sheet of pa-
per. For this reason, it may not be possible to obtain consistent
print quality over the entire envelope surface.

Many envelopes have a diagonal grain orientation (See
Grain on page 5-3). This orientation is more likely to wrinkle and
crease on its way through the printer. Before purchasing enve-
lopes for use with the printer, test a sample to verify the enve-
lope's suitability.
Do not use envelopes that have an encapsulated liquid adhe-
sive.
Avoid long printing runs consisting of envelopes only. Extensive
envelope printing can cause premature printer wear. To avoid
jamming due to curled envelopes, do not leave more than ap-
proximately 10 printed envelopes stacked in the paper trays dur-
ing multiple envelope printing.
Colored Paper
Colored paper should satisfy the same conditions as white bond
paper, listed in Paper Specifications on page
pigments used in the paper must be able to withstand the heat
of fusing during the printing process (up to 200 °C or 392 °F).
Preprinted Paper
Preprinted paper should have a bond paper base. The preprint-
ed ink must be able to withstand the heat of fusing during the
printing process, and must not be affected by silicone oil.
Do not use paper with any kind of surface treatment, such as the
type of paper commonly used for calendars.
Recycled Paper
Select recycled paper that meets the same specifications as the
white bond paper (see Paper Specifications on page
whiteness.
NOTE
Before purchasing recycled paper, test a sample on the printer
and check that the print quality is satisfactory.
