Clean the Printhead / Print Head Lenses

General Precautions

WARNING:

• Internal parts of the printer can be hot. Use caution when doors and covers are open.

• Keep all cleaning materials out of the reach of children.

• Do not use pressurized spray cleaning aids on or in the printer. Some pressurized sprays contain explosive mixtures and are not suitable for use in electrical applications. Use of pressurized spray cleaners increases the risk of fire and explosion.

• Do not remove the covers or guards that are fastened with screws. You cannot maintain or service any parts that are behind these covers and guards. Do not attempt any maintenance procedure that is not described in the documentation supplied with your printer.

CAUTION:

• When cleaning your printer do not use organic or strong chemical solvents or aerosol cleaners. Do not pour fluids directly into any area. Use supplies and cleaning materials only as directed in this documentation.

• Do not place anything on top of the printer.

• Do not leave the covers and doors open for any length of time, especially in well-lighted places. Light exposure can damage the drum cartridges.

• Do not open covers and doors during printing.

• Do not tilt the printer while it is in use.

• Do not touch the electrical contacts or gears. Doing so could damage the printer and cause the print quality to deteriorate.

• Ensure that any parts removed during cleaning are replaced before you plug in the printer.

Clean the Printhead Lenses

The printer is constructed with four printhead lenses. The printhead lenses require regular cleaning to maintain print quality. Clean the printhead lens every time the associated drum cartridge is replaced, or if print quality starts to degrade. For example, if prints have voids or light streaks through one or more colors, use the following instructions to clean the LED lenses:

WARNING:

If you accidentally get toner on your clothes, lightly dust them off as best as you can. If some toner remains on your clothes, use cool water, not hot, to rinse off the toner. If toner gets on your skin, wash it off with cool water and a mild soap. If you get toner in your eyes, wash it out immediately with cool water and consult a doctor.

CAUTION: Do not perform this procedure when the printer is copying or printing.
