Labels Labels consist of three parts: the top or face sheet that the printer prints on, the adhesive, and the carrier sheet (also referred to as the backing or liner). When printing on labels with this printer, observe the following: z Top sheets, which are the printing surface, are usually composed of xerographic paper. Label top sheets must provide good toner adhesion. z Carrier sheets must be compatible with the printer's fusing temperature (approximately 374° F, or 190° C) and the pressure of the fusing process. The carrier sheet also must be coated for easy release of the top sheet. CAUTION Do not remove labels from the carrier sheet and then print on the remaining labels; printer damage can result. z Adhesives must be able to withstand the printer's fusing temperature (approximately 374° F, or 190° C). The adhesives must not produce emissions that exceed exposure levels or threshold limits established by the U.S. Occupational Safety and Health Administration and other safety agencies. Adhesives must not come in direct contact with any part of the printer. No adhesive should be pressed out of the edges or between die-cuts (the cuts between individual labels). z Labels should be arranged so that the carrier sheet is not exposed. Using label stock with spaces between the horizontal rows of labels might result in labels peeling off during printing, causing jams and possible printer damage. Labels might be specifically manufactured to leave a margin around the outside edges that correspond to the outer margins of the printable area. Do not remove the excess top sheet material from the carrier sheet. Note Labels could meet all of the guidelines in this chapter and still not print satisfactorily because of the printing environment or other variables over which HP has no control.
