Adhesive-Backed Labels
The basic rule for printing on adhesive labels is that the adhesive must never come into con-
tact with any part of the printer. Adhesive paper sticking to the drum or rollers will damage
the printer.
Label paper must be manually fed.
Label paper has a structure comprising
three layers, as shown in Figure
B.1
. The
top sheet is printed on. The adhesive
layer consists of pressure-sensitive adhe-
sives. 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 pa-
per 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 jam problems.
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.
