B.3. Special Paper

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.
