chapter 6 This chapter provides suggestions for high-quality and economical printing and information for maintaining the toner cartridge and the printer.
Maintaining Toner Cartridge Toner cartridge storage To get the most from the toner cartridge, keep the following guidelines in your mind. • Do not remove the toner cartridge from its package until you are ready to use it. • Do not refill toner cartridges. The printer warranty does not cover damage caused by using a refilled cartridge. • Store toner cartridges in the same environment as the printer. • Do not remove a toner cartridge from the printer except to replace it, clean it or clear a paper jam.
Maintaining Toner Cartridge Redistributing Toner When toner is low, faded or light areas may appear on a printed page. You may be able to temporarily improve print quality by redistributing the toner. The following procedures may allow you to finish the current print job before replacing the toner cartridge. 1 Grasp the front cover by both sides of the cover and pull it toward you to open. 2 Remove the toner cartridge from the printer. CAUTIONS: • Avoid reaching too far into the printer.
Maintaining Toner Cartridge 3 Gently shake the toner cartridge from side to side 5 or 6 times to redistribute the toner. Note: If the toner gets on your clothing, wipe it off with a dry cloth and wash clothing in cold water. Hot water sets toner into fabric. 4 Reinsert the toner cartridge into the printer. Be sure that the toner cartridge snaps in its place. 5 Firmly close the cover. If the print remains light Remove the old cartridge and install a new toner cartridge.
Cleaning the Printer To maintain print quality, follow the cleaning procedures below every time the toner cartridge is replaced or whenever print quality problems occur. As much as possible, keep the printer free from dust and debris. Notes: • Do not use ammonia-based cleaners or volatile solvents such as thinner, on or around the printer. These can damage the printer. • While cleaning the inside of the printer, be careful not to touch the transfer roller (located underneath the toner cartridge ).
Cleaning the Printer 4 Reinsert the toner cartridge and close the cover. 5 Then, plug in the power cord, and turn the printer on. Printing a cleaning sheet Printing a cleaning sheet cleans the drum inside the toner cartridge. Use this process if you are experiencing blurred, faded or smeared printouts. This process will produce a page with toner debris, which should be discarded. 1 Make sure the printer is turned on and in the Ready mode and that there is paper loaded in the automatic input tray.

Paper Specifications Guidelines for Using Paper For best results, use conventional 75 g/m2 (20 lb) paper. Make sure the paper is of good quality, and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, voids, and curled or bent edges. If you are unsure of what type of paper you are loading (such as bond or recycled), check the label on the package of the paper. The following problems with paper cause print quality deviations, jamming, or even damage to the printer.
Paper Specifications Paper Specifications Category Specifications Acid Content 5.5 ~ 8.0 pH Caliper .094 ~ .18 mm (3.0 ~ 7.0 mils) Curl in Ream Flat within 5 mm (.02 in.) Cut Edge Conditions Cut with sharp blades with no visible fray. Fusing Compatibility Must not scorch, melt, offset, or release hazardous emissions when heated to 200 °C (392 °F) for .1 second.
Paper Specifications Printer and Paper Storage Environment Ideally, the printer and paper storage environment should be at or near room temperature, and not too dry or humid. Remember that paper absorbs and loses moisture rapidly. Heat works with humidity to damage paper. Heat causes the moisture in paper to evaporate, while cold causes it to condense on the sheets. Heating systems and air conditioners remove most of the humidity from a room.
Paper Specifications Envelopes Envelope construction is critical. Envelope fold lines can vary considerably, not only between manufacturers, but also within a box from the same manufacturer. Successful printing on envelopes depends upon the quality of the envelopes. When selecting envelopes, consider the following components: • Weight: The weight of the envelope paper should not exceed 90 g/m2 (24 lb) or jamming may occur. • Construction: Prior to printing, envelopes should lie flat with less than 6 mm (0.
Paper Specifications Envelopes with Double Side Seams Double side-seams construction has vertical seams at both ends of the envelope rather than diagonal seams. This style may be more likely to wrinkle. Be sure the seam extends all the way to the corner of the envelope as illustrated below.
Paper Specifications Labels CAUTIONS: • To avoid damaging the printer, use only labels recommended for laser printers. • To prevent serious jams, always use the face-up output slot. • Never print on the same sheet of labels more than once or print on a partial sheet of labels. When selecting labels, consider the quality of each component: • Adhesives: The adhesive material should be stable at 200 °C (392 °F), the printer’s fusing temperature.
