Routine Maintenance

Keep your machine in optimum condition by cleaning it on a regular basis. It is
a good idea to clean the drum unit during this routine. Avoid using thinners or
other organic solvents and do not use water.

Cleaning the Document Scanner

1

Unplug the telephone line, and then the power cord.
When you reconnect these lines later, connect the power cord first, and then the
telephone line.

2

Lift the control panel cover.

3

Clean the white bar and glass cover
under the white bar.
Moisten a small, clean, soft, lint-free
cloth with isopropyl alcohol and
carefully remove dirt from the glass
cover and the white bar.

Cleaning the Printer

Caution

■ Do not use isopropyl alcohol to remove dirt from the control panel. It may crack the

panel.

■ Do not use isopropyl alcohol to clean the scanner window.
■ Do not touch the scanner window with your finger.
■ The drum unit contains toner, so handle it carefully. If toner scatters and your hands

or clothes get dirty, immediately wipe or wash it off with cold water.

1

Open the front cover.

2

Remove the drum unit assembly.
