Regular Maintenance
You can keep your machine in optimum condition by cleaning it on a regular basis.
It is a good idea to replace the toner cartridge and the drum unit during this routine.
Avoid using thinners or other organic solvents to clean the machine and do not use
water.
Follow the steps below:
1. Unplug the telephone line and then the power cord.
When you reconnect these lines later, make sure to connect the power cord first,
then the telephone line.
2. Wipe dirt off the machine using a slightly damp clean cloth.
3. Clean the white plate and the glass cover.
Moisten a small piece of clean soft, lint-free cloth with isopropyl alcohol and
carefully remove dirt from the glass cover and the white plate of the scanner.
* Do not use isopropyl alcohol to remove dirt from the control panel. It may cause a
crack on the panel.
4. Wipe the gears and electric terminals with isopropyl alcohol on a cotton swab.
Gently wipe the scanner window and the toner sensor with a clean soft dry cloth.
Open the control panel.
