SENSOR SETUP WITHVERSION 5.2 OR GREATER
Manufacturing sets all three sensors before a printer is
shipped. Service needs to adjust the sensor if a
sensor component fails in the field or for specific
customer supplies. Use Sendfile Version 2.21 (or
greater) to set the sensor values. The three sensors
are: aperture (center), black mark (center), and die cut
(edge).

POWER UP SENSORRECOGNITION
During power up initialization the software checks a
reserved area in flash to see if the printer has the V5.2
sensor system hardware installed. If it does then the
V5.2 sensing is activated. If not then the daughter
board is checked to see if the model switch is set to
the 9835 sensing system. If no daughter board is
installed, then the 9820/9830 sensor system control
software is enabled. For the 9820/30 and for the
M9835 the selectable modes are transmissive,
reflective, and non-index (continuous) which currently
exists in these models.
