Label Specifications When selecting labels, consider the quality of each component: • Adhesives: The adhesive material should be stable at 200 degrees C (392 degrees F), which is the printer’s fusing temperature. • Arrangement: Only use labels with no exposed backing between them. Labels can peel off sheets with spaces between the labels, causing serious jams. • Curl: Prior to printing, labels must lie flat with no more than 13 mm (.5 in.) of curl in any direction. • Condition: Do not use labels with wrinkles, bubbles, or other indications of separation. CAUTION: To avoid damaging the printer, use only labels recommended for laser printers, such as HP-brand labels.
To prevent serious jams, always use Tray 1 to print labels and always use the rear output bin. Never print on the same sheet of labels more than once or print on a partial sheet of labels. Table 2-6. Label Specifications C4170-90959 Media Specifications 35 Description Specification Adhesive Must not be on any external surfaces of the label before, during, or after printing. Label construction and die-cutting must not let labels peel off during transport, printing, or fusing. Caliper Must not exceed 0.19 millimeter (0.007 inches). See “Caliper Field Test” (page 39). Curl In ream: flat within 5 millimeter (0.2 inches). See “Curl Field Test” (page 41).
Surface Resistivity 2.0 to 15 X 10 to the 10th ohm square. See “Tools and Suppliers” (page 42). Volume Resistivity 1.2 to 15 X 10 to the 11th ohm-centimeter. See “Tools and Suppliers” (page 42) Finishing Precision Cut sheet within 0.79 millimeters (0.031 inches) of nominal and +0.20 degrees square. Fusing Compatibility All adhesives, carrier sheets, top sheets, and other materials used in label construction must be compatible with the heat and pressure of the fusing process. Materials must not discolor, melt, offset, or release hazardous emissions when heated to 200 degrees Celsius (392 degrees Fahrenheit) for 0.1 second. See “Fusing Compatibility Field Test” (page 42).
