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

1Unplug the telephone line and then the power cord.

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

2Lift the control panel cover.

3Clean 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.
