CHAPTER 7 CONTROLS AND EXTERNALS
AC power is supplied to the DC power supply PCB and other loads when the door
switch (DSW1) and the power switch (SW1) are turned on.
The DC power supply PCB generates +24 VA, +24 VB, +12 V, and +5 V.
The drum heater is supplied with power when the power switch is turned off.
The DC power supplied to the DC controller is cut off when the copier's power switch
is turned off; to back up any data, the RAM on the DC controller PCB is equipped with a
lithium battery (BAT101).
Reference:
The tolerances of the DC voltage generated by the DC power supply PCB are as
follows:
• +24 VA ±3%
• +24 VB ±10%
• +12 V ±10%
• +5 V ±3%
Caution:
Replace the lithium battery only with the one listed in the Parts Catalog. Use of
another battery may present a risk of fire or explosion. The battery may present a
fire or chemical burn hazard if mistreated. Do not recharge, disassemble or dispose
of it in fire. Keep the battery out of reach of children and discard any used battery
promptly.
