Appendix-6 ADVANCED OPERATION GUIDE
Transparency (overhead projection film)
Transparency must be able to withstand the heat of fusing during the printing
process. It should satisfy the conditions in the table below.
To avoid trouble, transparency must be delivered face-up.
If transparency jams frequently, pull the top of the sheet very gently as it leaves the
machine.
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 machine. Adhesive paper sticking to the drum or
rollers will damage the machine.
Label paper must be manually fed.
Label paper has a structure comprising 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.
