Maintaining the Machine

CAUTION

Read all caution and warning labels carefully, making sure to follow any instructions contained in them. These labels are located on the inside of the machine’s covers and the interior of the body.

Handle the machine with care to preserve its life. Abuse handling may cause damage and void your warranty. If dust and paper scraps remain on the inside or outside of the machine, machine performance and print quality will suffer, so the machine should be cleaned periodically. Keep the following guidelines in mind.

WARNING!

Turn off the machine, unplug the power cord, and disconnect interface cable before cleaning. Do not spill water or detergent into the machine; otherwise the machine will be damaged and an electric shock may occur.

CAUTION

The fuser unit is hot. When the engine cover is opened, the fuser unit temperature drops gradually (one hour wait time).

„Be careful when cleaning the inside of the machine or removing media misfeeds, as the fuser unit and other internal parts may be very hot.

„Do not place anything on top of the machine.

„Use a soft cloth to clean the machine.

„Never spray cleaning solutions directly on the machine’s surface; the spray could penetrate through the air vents of the machine and damage the internal circuits.

„Avoid using abrasive or corrosive solutions or solutions that contain sol- vents (such as alcohol and benzene) to clean the machine.

„Always test any cleaning solution (such as mild detergent) on a small inconspicuous area of your machine to check the solution’s performance.

„Never use sharp or rough implements, such as wire or plastic cleaning pads.

„Always close the machine’s covers gently. Never subject the machine to vibration.
