CHAPTER 10 SIDE PAPER DECK
F. Controlling the Deck Motor
1. Controlling the Deck Main Motor (M101)
The deck main motor is controlled by the copier's DC controller. Figure 10-110 shows the
circuit that drives the deck main motor, and has the following functions:
[1] Turning on and off the deck main motor.
[2] Switching the speed or rotation of the deck main motor.
a. Turning On and Off the Motor
When the deck main motor drive signal (DMON) from the copier goes '1', the motor drive
circuit turns on so that the motor starts to rotate at a specific speed. On the other hand, when the
deck main motor drive signal (DMON) goes '0', the motor drive circuit goes off to stop the motor.
The copier's DC controller monitors the rotation of the deck motor in reference to the deck
main motor PLL lock signal (DMPLK); if the motor PLL lock signal remains '1' for 900 msec or
more while DMON is '1' for some reason, the copier's control panel will indicate 'E043' .
