135Using Print Materials Using Print Materials Using Your Printer Polyester Labels Polyester labels are less heat sensitive than vinyl labels but are also non-absorbing. Liners for polyester labels can be thinner, but requirements for topcoats and printer maintenance are similar to those for vinyl labels. Topcoats Topcoats for non-paper labels are generally water based or solvent based. Care should be taken to avoid topcoats containing chemicals that emit hazardous fumes when heated or put under pressure. Topcoats affect the print quality and adhesion of toner to the label (fuse grade). To prevent fuser damage, topcoats must be able to withstand temperatures up to 212°C (414°F) and pressure up to 25 psi for one second. Water-based topcoats tend to be higher in electrical conductivity than solvent-based topcoats. When using some water-based topcoats with heavy liners, thefuse grade(how well the toner adheres to the page) may fall below acceptable levels. Print quality may degrade with heavier liners. Using a lighter liner may reduce the appearance of splatter. Print quality with some water-based topcoats may not be acceptable for all applications. Solvent-based topcoats tend to be lower in electrical conductivity than water-based topcoats. When using some solvent-based topcoats with heavy liners, fuse grade may fall within acceptable levels. Print quality may degrade with heavier liners. Using a lighter liner may reduce the appearance of splatter. Print quality with some solvent-based topcoats may not be acceptable for all applications. Perforations If the liner is perforated, make sure that no adhesive accumulates on the top or back of the label sheet. The perforation line should stop 1.6 mm (0.06 in.) from the edge of the sheet to prevent jams and tearing of the sheet within the printer path. Perforations
Using Print Materials136 Using Print Materials Using Your Printer should be ironed to reduce the thickness caused by the perforation process and to reduce nesting of forms. Edges should be smooth and clean with no roll-over.Laser-perfs(also known asmicro-perfs ordata-perfs)of20to30perfsperincharegenerallymorestable and are preferred. The smaller perforations do not normally nest or create excessive paper dust and debris (paper chaff). Make sure paper chaff created during the conversion process is removed before packaging. Label Design Stripped edge matrixis the area around the outer edge of the cut- sheet, which is sometimes removed before printing.Total strip matrix, the non-print area around each die-cut label, is also sometimes removed before printing. This helps you peel the labels from the backing. Butt-cut labelsare cut flush to one another, with no area in- between. Butt-cut labels may or may not have an edge matrix removed. Die-cut labelsare cut with a non-print area between each label. If you are using a butt-cut or die-cut label, make sure adhesive contamination does not occur. We recommend a maximum stripped edge matrix of 3 mm (0.125 in.) along the outer edgeor zone coating with a non-adhesive perimeter of 1 mm. For best results, do not print within 1.02 mm (0.04 in.) of the edge of the label, of the perforations, or between die-cuts of the label. The use of cut-sheet labels that have adhesive to the edge of the sheet will contaminate your printer and cartridge, and could void your printer and cartridge warranties. When using vinyl, polyester, paper, or dual-web labels without zone coating, butt-cut labels without anystringers(adhesive pulls) and with a stripped edge matrix of 3 mm (0.125 in.) are preferred. If a total strip matrix is used, print before removing the matrix. If matrix must be removed before printing, round all corners and make sure adhesive is not exposed. Minimize die-cutting,
137Using Print Materials Using Print Materials Using Your Printer especially through the backing material. Die-cuts should be at least 1 mm (0.04 in.) from printed areas. Back slits or pop-out windows are not recommended. A non-print area (waste strip)aroundtheouteredgeofthesheetis also recommended as part of the label design. For a letter size sheet in portrait orientation, allow 8.38 mm (0.33 in.) for the non-print area along the top and bottom edges. Allow 6.35 mm (0.25 in.) for the non-print area along both sides. 8.38 mm (0.33 in.)Non-Print Area Non-Print Area 8.38 mm (0.33 in.) 6.35 mm Non-Print Area Non-Print Area6.35 mm (0.25 in.)

Using Print Materials138 Using Print Materials Using Your Printer Waste strips prevent you from printing too close to the edge of the sheet. Print should be placed at least 1 mm (0.04 in.) from die cuts and perforations. We recommend zone coating of the adhesive at least 1 mm (0.04 in.) away from edges to control adhesive contamination. Ifzonecoatingoftheadhesiveisnotpossible,a3mm (0.125 in.) strip should be removed on the leading and driver edge, and a non-oozing adhesive should be used. If the labels are vinyl, remove a 3 mm (0.125 in.) strip from the leading edge to prevent labels from peeling in the fuser. Portrait orientation is preferred, especially when printing bar codes. For more information, refer to theCard Stock & Labels Guide,which is available from Lexmark. Card Stock Guidelines Card stock is single ply, and has a large array of properties. The orientation of paper fibers, moisture content, thickness, and texture can all affect printing on card stock. See page 125 for information on the preferred weight for the grain direction of print materials. When printing on card stock, be sure to selectCard Stockin the PAPER TYPEmenu in thePAPER MENU. Preprinting, perforation, and creasing can significantly affect the print quality. Preprinting introduces semi-liquid and volatile components in the printer. Perforation and creasing of forms may cause nesting or interlocking that leads to paper handling or jamming problems. After printing approximately 10,000 page sides of card stock (or each time you replace the print cartridge), complete the following steps to maintain printer feeding reliability:
139Using Print Materials Using Print Materials Using Your Printer 1Print 5 sheets of paper. 2Wait approximately 5 seconds. 3Print 5 more sheets of paper. For more information, refer to theCard Stock & Labels Guide,which is available from Lexmark. Transparency Guidelines The printer can print directly on transparencies specifically designed for use in laser printers. Print quality and durability depend on the transparency used. You should try samples of any transparencies you are considering using with the printer before buying large quantities. We recommend the Lexmark Optra 1200 dpi Laser Printer transparency, part number 1402809 (A4-size sheets) or 1402810 (letter-size sheets). The Paper Type setting should be set to Transparency to prevent jams. See page 64. The laser printing process heats transparencies to a temperature of 212 oC (414oF) when Paper Type is not set to Transparency. If you select Transparency as your Paper Type, the printer heats the transparencies to a temperature of 180 oC (356oF). Use only transparencies that are able to withstand these temperatures without melting, discoloring, offsetting, or releasing hazardous emissions. Check with the manufacturer or vendor to determine whether the transparencies are usable with laser printers that heat transparencies to 180 oC (356oF) or 212oC (414oF). Transparencies can be fed automatically from all standard and optional trays for all printer models and from the multipurpose feeder on the Optra S 1855, Optra S 1625 or Optra S 1255. Be careful when you handle transparencies. Fingerprints on the surface of the transparency cause poor print quality.
