3.3 CARD PATH ELEMENTS
The upper part of Figure 3-1 points out the rollers that transport Cards. The lower part
identifies the sensors that detect the various events that occur during card printing. These
LED-Photo transistor sensors signal reception of cards from the Card Feeder, ribbon
initialization, Head Up and Head Down Print Head cam positions, and whether the Print
Head is open or Latched. The Flag Sensor signals incremental ribbon advances. This
signals the need for downward adjustmentsin ribbon take up travel as the accumulation of
ribbon increases the effective Take Up diameter. The Ribbon Panel Sensor signals when a
yellow panel is next in line for imaging.
