2.2.2.6 Motor Drive Circuits

This printer is equipped with 2 kinds of motors; CR motor and PF motor. Since they are all driven by
UDN2917EB, they use the same control system.

CR Motor Drive Circuit
The phase control signal for the CR motor is output from the port 74, 77 of IC2 gate array to the port
26 and 43 of the IC14 UDN2917EB. IC14 determines the phase mode according to the signal sent.
The current control signal is also produced in IC2 gate array and output from the port 72, 73, 75 and
76 to the port 1, 2, 23 and 24 of the IC14 UDN2917EB. IC14 outputs signals to the each phase of the
CR motor and drive them.

PF/Pump Motor Drive Circuit
PF/Pump motor drive circuit basically consists of the same circuit as the CR motor drive circuit.
The phase control signal for the PF/Pump motor is output from the port 50 and 59 of IC2 gate array
to the port 26 and 43 of the IC14 UDN2917EB. IC14 determines the phase mode according to the
signal sent. The current control signal for each phase is also produced in IC2 gate array and output
from the port 55, 56, 57 and 58 to the port 1, 2, 23 and 24 of the IC14 UDN2917EB. IC14 outputs
signals to the each phase of the PF/Pump motor and drive them.
