Appendix
To prevent printing problems, feed transparencies into the printer one
sheet at a time from the MP tray. Always load the transparencies vertically
(with the long edge towards the printer).
If the transparencies have rough edges on the back, it may cause a paper
jam. Remove the rough edges, reverse the sides, feed the sheet from the
opposite edge, or flip the sheet over.
When unloading transparencies (e.g., for clearing jams), hold them
carefully by the edges to avoid leaving fingerprints on them.
Labels
Labels must be fed from the MP tray.
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.
