2-8 Paper Handling
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 has a structure
comprising of three layers, as
shown in the diagram. 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 used.
Due to the complexity of its
composition, adhesive-
backed label paper is particularly likely to give printing problems.
Adhesive label paper must be entirely covered by its top sheet, with no
spaces between the individual labels. Labels with spaces in between are
liable 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
Up to 10 postcards can be
loaded at a time. 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.
