1-10 ADVANCED OPERATION GUIDE
Transparency
Transparency must be able to withstand the heat of fusing during the
printing process. It should satisfy the conditions given in the table below.
If transparency jams frequently, pull the top of the sheet very gently as it
leaves the printer.
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 printer. Adhesive paper
sticking to the drum or rollers will damage the printer.
Label paper must be manually fed.
Label paper has a structure comprised 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.
