Laminator Components
Sensors
Name Function
Interstage
This sensor is located between the upper and lower duplex assemblies
and detects a card as it passes from the upper duplex to the lower
duplex.
Duplex Exit
The duplex exit sensor is an optical interruption sensor that detects the
presence of a card as it leaves the duplex module. This sensor also
registers the card for the first laminator.
Duplex Home
The duplex home sensor determines the rotational position of the duplex
flipper. The flipper has three flags that pass through the sensor.
Card
Registration
This sensor is located between the first and second laminators, and
registers the card for the second laminator.
Card Exit
This sensor is located just before the output hopper and detects when a
card leaves the printer.
Foil Motion
Each laminator has a foil motion sensor. This is a reflective sensor that
detects the teeth on an encoder wheel within the supply cassette.
Foil Index
Each laminator has a foil index sensor. This is a reflective sensor that
detects index marks on the supply spool. It also detects a smart card
cutout (if present) in the foil.
Heater Home
Each heated roller assembly has a heater home sensor. This interruption
sensor detects a flag on the heater lift cam to determine the vertical
position of the heated roller.
Thermocouple
Each heated roller has a thermocouple for determining temperature. A
thermocouple is made from two dissimilar metals connected together. As
temperature increases, the voltage between the two metals increases.
Motors
Name Function
Transport Motor
The transport motor drives the upper (L1) platen roller through a gear,
which also drives the main transport belt. This is a 2-phase (4-wire), 24-volt
stepper motor.
Heater Lift
Motors
Each heater assembly has a heater lift motor. The DC motor operates an
eccentric cam shaft to raise and lower the heated roller.
Foil Advance
Motors
Each foil supply cassette is driven by a stepper motor through a geartrain.
The final gear has a square hole in the center to engage the capstan
roller in the supply cassette.
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).
