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, 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

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

■ 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.
