Postcards
One postcard can be loaded at a time. 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 postcard on
a flat place and rub the edges with, for example, a ruler to smooth them.
Envelopes
One envelope can be loaded at a time. Envelopes should be fed in the face-up position, right edge first.
Since the composition of an envelope is more complex than that of ordinary paper, it is not always possible to ensure
consistent printing quality over the entire envelope surface.
Normally, envelopes have a diagonal grain direction. This direction can easily cause wrinkles and creases when envelopes
pass through the printer. Before purchasing envelopes, make a test print to check whether the printer accepts the
envelope.
• Do not use envelopes that have an encapsulated liquid adhesive.
• Avoid a long printing session for envelopes only. Extended envelope printing can cause premature printer wear.
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
Top sheet (white
backing sheet) holds the labels until used. Due to the complexity of its
bond paper)
composition, adhesive-backed label paper is particularly likely to give
Adhesive
printing problems.
Carrier sheet
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.
