CHAPTER 3 MECHANICAL SYSTEM
I. PREPARATIONS/POINTS TO NOTE
A. Turning Off the Main Power Switch
Before starting disassembly/assembly work, be sure to turn off the main power switch of the
copier in which the board is installed, and disconnect the power plug.
In addition, keep the following in mind:
1. When the main power switch is turned off, the backup secondary battery used to retain the
fax memory images starts to operate. Be sure to finish the work within one hour if it requires
turning off the main power switch.
2. Check the Communications Memory lamp on the control panel to find out whether there is a
fax memory image. If it is on, indicating the presence of an image, print out the image before
turning off the main power switch and disconnecting the power plug.
3. Some units remain powered even when the copier’s control panel power switch is turned off.
Be sure to turn off the main power switch.
4. Exercise care. Opening the front door will not turn off the power when both the control panel
power switch and the main power switch are on.
5. If the Communications Memory lamp is flashing while the handset (accessory) is being used,
check to find make sure that the LINE modular jack is securely fitted in place.
