Using Print Materials Using Your Printer Paper Labels Generally, cut-sheet paper labels work well with your printer. Labels with coating or sizing used to make the paper liquidresistant should be avoided. They decrease toner adhesion and increase fuser contamination from toner. Paper labels, at a minimum, should be equivalent in weight and rigidity to 20 lb xerographic bond paper. Dual-Web Paper Labels Dual-web paper labels are paper labels combined with a sheet of paper stock to form a cut-sheet design. The liner must be rigid enough to withstand the pick force of the printer. The overlay of the two print materials must be thin enough to allow the label sheet to remain flat in the tray. The sheet should have no adhesive exposed in the overlay area or anywhere along the front or back of the two materials. A 1 mm (0.04 in.) non-glue strip is recommended along the edge of the overlay. The label portion is usually a paper label. The same guidelines applicable to paper labels are applicable to these labels. Testing is recommended before purchasing large quantities of dual-web paper labels. Vinyl Labels Some vinyl labels work well with your printer. It is always recommended to print several samples of the labels you are considering before buying large quantities. Since vinyls are heat sensitive, the liners need to be thick enough to absorb excess heat and prevent melting. Thin liners or low peel strength adhesive may lead to peeling of vinyl labels, which will require printer servicing. Vinyls are non-absorbing, which leads to toner build-up in the fuser and may require special printer maintenance. Vinyls must have a topcoat to provide good toner adhesion. 134 Using Print Materials
