CP60 and CP60 Plus Service Manual 2-5
Motors
The CP60 and CP60 Plus printers have up to five motors depending on the
configuration. The three DC motors are all similar, with an integral reduction
geartrain and 24-volt operation. The speed of the motors is controlled by pulse
width modulation. While the motors are reversible, some are wired to operate in
one direction only. The duplex step motor operates at 24 volts, but the transport
step motor operates at 40 volts.
Name Function
Pick Motor
The pick motor drives the pick roller to bring a card into the system. The
motor is wired for unidirectional operation and cannot be reversed by
the control board. One wire is tied to ground and the other wire is the
control. This motor is driven by a single channel in the motor driver.
Transport Motor
The transport motor drives the platen roller through a gear, which also
drives the main transport belt. This is a 2-phase (4-wire), 40-volt stepper
motor.
Cam Motor
The cam motor rotates the printhead cam, which operates the
printhead lifters. This raises and lowers the printhead into position for
printing or permitting a card to pass beneath. This motor is wired bi-
directional and uses two channels from the motor controller so that it
can be reversed. (However at this time, the motor is not operated in
reverse.)
Ribbon Motor
The ribbon motor drives the gear train of the ribbon cartridge to
advance the ribbon during printing. The motor is wired for
unidirectional operation and cannot be reversed by the control board.
One wire is tied to ground and the other wire is the control. This motor is
driven by a single channel in the motor driver.
Duplex Motor
The duplex motor drives a gear on the duplex clutch. The clutch
permits a single motor to either operate the rollers, or rotate the entire
flipper assembly (this is discussed in more detail on page
2-6). This is a
2-phase (4-wire), 24-volt stepper motor.
