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
Wipe dirt off the machine with a slightly damp clean cloth.
4
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 or toner sensor.
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.
