1.4 Controlling the Main Motor (M2)

1.4.1 Outline

The functions of the main motor control circuit are as shown in T02-104-01; for a block diagram of the circuit, see F02-104-01.

Item	Description
Power supply	24 V from the DC power supply PCB.
Drive signal	Signal (MM_ON) from the DC controller PCB.
Operation/drive assembly	Waste toner feed screw
	Cleaner assembly
	Registration roller
	Manual pickup assembly
	Left deck feeding roller 2
	Developing unit
Control	ON/OFF control
	Constant speed control
Error detection	‘E010’ (error code)
	T02-104-01

[1]When the main motor drive signal (MM_ON) goes ‘1’, the main motor starts to rotate.

[2]When the main motor starts to rotate, the clock pulse signal (MM_LOCK=1) is gener- ated. If the DC controller PCB detects a fault in the clock pulse signal, the machine will indicate ‘E010’ in its control panel.
