2-10 Theory of Operation
Sequence of Operation
Power-on Initialization
1. When the printer is turned on, it begins its initialization routine.
2. As the main control board initializes itself, the status light on the front of the
printer will be steady amber.
3. After the control board is initialized, the status indicator will cycle through
red, amber, and green.
4. While the control board examines and initializes external components, the
indicator will flash green.
A. The system checks for smart card, magnetic stripe, and duplex modules.
B. The duplex module is initialized, and the rollers are operated for
sufficient time to ensure no cards are present in the module.
C. The printhead cam motor is cycled and homed.
D. The transport is initialized and then operated for sufficient time to ensure
that the card track is clear.
E. The ribbon type is identified. This may or may not result in the ribbon
motor being energized for a short time to detect a ribbon encoder change.
5. When the printer has finished its initialization procedure and is ready to
process cards, the status light will turn green.
Default Card Printing Sequence
1. After the card data has been sent to the printer, it begins the card
personalization process.
2. The card is picked and passes through the cleaning rollers.
3. After the leading edge of the card passes through the cleaning rollers, the
card is detected by the input sensor. The trailing edge of the card is registered
for positioning.
4. The card is first sent to the smart card area.
A. When the card is approaching the location of the smart card contacts, the
solenoid engages and pulls the contacts down.
B. The leading edge of the card makes contact with the smart card sensor
(mechanical switch in the contact block) and the transport stops.
C. The card is programmed by an external application. The printer acts only
as an interface to the card.
D. The external application notifies the printer that smart card interaction is
complete, and control is returned to the printer.
