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 machine. Adhesive paper sticking to the drum or rollers will damage the machine.
Label paper must be manually fed.
Label paper has a structure comprising 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 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.
The table below lists the specifications for adhesive label paper.
Postcards
Fan the stack of postcards and align the edges before
loading them in the MP tray. Make sure the postcards
you are going to set are not curled. Feeding curled
postcards may cause paper jams.
Some postcards have rough edges on the back (those
are created when the paper is cut). In this case, put the
postcards on a flat place and rub the edges with, for
example, a ruler to smooth them.
