8. Solenoid and clutch drive circuit
The solenoid and clutch drive circuit uses non-inversion transistor
arrays TD62318AP (IC17, 18) which turn on the solenoids and
clutches when the input signal is at L; and an inversion transistor
array TD62004AP (IC5) which turns on the solenoids and clutches
when the input signal is at H.

clutches when the input signal is at L; and an inversion transistor
array TD62004AP (IC5) which turns on the solenoids and clutches
when the input signal is at H.
The expansion I/O PG port which controls the solenoids and clutches
is an open collector type which becomes high impedance when reset-
ting and H output. For this reason, to turn on the solenoids and
clutches at L level, the non-inversion type TD62318AP is used for
driving the PG port. On the other hand, the expansion I/O’s PC port is
at L level at resetting. For this reason, for driving the PC port, the
inversion type TD62004AP which turns on the solenoids and clutches
at H level is used.

9. Jogger motor drive circuit
The jogger motor control signal (JMA, A/, B. B/) from the expansion
I/O (IC3) is input into the driver IC TD62004AP (IC8), to drive the
jogger stepping motor which aligns the sheets sidewise.

The driving method is unipolar, 1-2 phase excitement, constant-volt-
age method.

Here is the driving pattern for the jogger motor.
