2.2 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. Adhe- sive 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.

Top sheet (White bond paper)

Adhesive 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 apt to peel off, causing serious paper jam prob- lems.

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.

Item	Specification
Weight of top sheet	44 to 74 g/m2 (12 to 20 lb/ream)
Composite weight	104 to 151 g/m2 (28 to 40 lb/ream)
Thickness of top sheet	0.086 to 0.107 mm (3.9 to 4.2 mils)
Composite thickness	0.115 to 0.145 mm (4.5 to 5.7 mils)
Moisture content	4 to 6 % (composite)

Envelopes

The printer can print on envelopes using paper with a basis weight of 60 to 79 g/m2 (16 to 21 lb/ream). Envelopes must be manually fed.

An envelope is a more complex object than a single sheet of pa- per. For this reason, it may not be possible to obtain consistent print quality over the entire envelope surface.

Many envelopes have a diagonal grain orientation (See Paper Grain on page 5-3). This orientation is more likely to wrinkle and crease on its way through the printer. Before purchasing enve- lopes for use with the printer, test a sample to verify the enve- lope’s suitability.

Do not use envelopes that have an encapsulated liquid adhe- sive.

Avoid long printing runs consisting of envelopes only. Extensive envelope printing can cause premature printer wear. To avoid jamming due to curled envelopes, do not leave more than ap- proximately 10 printed envelopes stacked in the paper trays dur- ing multiple envelope printing.

Colored Paper

Colored paper should satisfy the same conditions as white bond paper, listed in Paper Specifications on page 5-1. In addition, the pigments used in the paper must be able to withstand the heat of fusing during the printing process (up to 200 °C or 392 °F).

Preprinted Paper

Preprinted paper should have a bond paper base. The preprint- ed ink must be able to withstand the heat of fusing during the printing process, and must not be affected by silicone oil.

Do not use paper with any kind of surface treatment, such as the type of paper commonly used for calendars.

Recycled Paper

Select recycled paper that meets the same specifications as the white bond paper (see Paper Specifications on page 5-1) except whiteness.

NOTE

Before purchasing recycled paper, test a sample on the printer and check that the print quality is satisfactory.
