tray motor
The recording paper placed in the optional recording paper tray is fed by transmitting the power
obtained by driving the optional paper tray motor connected to CN3 to the pickup roller while
controlling the paper feed timing by the optional paper pickup solenoid.
To feed the recording paper, the I/OP-2 GA turn the CMD1 signal to HIGH level and sends it to
the Optional tray MPU. The Optional tray MPU sends the I01, I02, I11 and I12 signals and the
PHASE1 and PHASE2 signals to the motor driver (IC2). The motor driver generates FDA,
FDB, FDAX and FDBX signals based on the signals input and sends them to the optional paper
tray motor for driving. Then the Optional tray MPU turns the PF signal to HIGH level to turn on
Q4. This causes the PF signal to be at GND level to drive the optional paper pickup solenoid
and transmit power to the pickup roller for feeding the recording paper.
