1.6 Controlling the Deck
1.6.1 Controlling the Deck Main Motor (M101)
The deck main motor is a stepping motor controlled by the DC controller of the host ma-
chine. The following figure shows the circuit used to drive the deck main motor, and has the
following functions:
[1] Turing on and off the deck main motor.
[2] Changing the speed of rotation of the deck main motor
a. Turning On and Off the Motor
The deck main motor is turned on or off by controlling the output of the pulse signals
from the host machine. (DMMA, DMMA*, DMMB, DMMB*).
b. Changing the Speed of Rotation of the Motor
The deck is designed to automatically change the speed at which paper is moved in con-
sideration of future models of its host machine. As such, its speed is changed by the motor
clock signals (M-CLK) arriving at the deck driver PCB from the DC controller of its host
machine.
