Theory of Operation
Name Function
Card Input
The card input sensor is an interruption sensor that detects the presence of
a card at the entrance of the printer and registers the trailing edge of the
card for printing.
Magnetic
Stripe Optical
Encoder
This encoder monitors the rotation of the idler roller in the magnetic stripe
module. It provides positional feedback to the module to ensure proper
magnetic encoding.
Duplex Entry
The duplex entry sensor is an optical interruption sensor that detects the
presence of a card as it enters and leaves the duplex module.
Duplex Home
The duplex home sensor determines the rotational position of the duplex
flipper. The flipper has three flags that pass through the sensor.
Input Hopper
Empty Sensor
Option
This reflective sensor detects when the card hopper has no cards left. It
functions only when special software is created to use it.
Motors
The printer engine has 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 connected 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. The lifters raise and lower the printhead into
position for printing or permitting a card to pass beneath.
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 connected 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 operate the rollers, or to rotate the entire
flipper assembly (this is discussed in more detail on page 2-7). This
is a 2-phase (4-wire), 24-volt stepper motor.
