2-8  Theory of Operation 
 
Sequence of Operation 
Power-on Initialization 
1.  When the printer is plugged in, it begins its initialization routine. (There is no 
On/Off switch.) 
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.  It 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 Production 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.
