Testing the SENSORS Using LEDs

SENSORS S1-S13 are tied to LEDs which can be used in a test mode to monitor the operation of the
SENSORS. The SENSORS report to MICROS on several different CIRCUIT BOARDS.
SENSORS S1- S5 and S10-12 monitor film feed functions and report to the slave MICRO on the
•
FEEDER CONTROL BOARD. The LEDs for these SENSORS are also on the FEEDER CONTROL
BOARD. SENSOR locations in the IMAGER and locations of the corresponding LEDs are shown in
Figure 7-11. (See paragraph 7-4-1-1 for testing procedure).
SENSOR S13 (ROLLBACK OPEN) reports to the slave MICRO on the RF TAG INTERFACE BOARD.
•
The LED for the SENSOR is located under the ROLLBACK TRAY, near the RF Tag electronics. (See
paragraph 7-4-1-2.)
SENSORS S6 (PLATEN FILM), S7 (OPTICS Home), and S8 (VERTICAL TRANSPORT) report to the
•
master MICRO on the MCS BOARD. The LEDs for these SENSORS are located on the MCS BOARD.
SENSOR locations in the 8100 LASER IMAGER and locations of the corresponding LEDs are shown
in Figure 7-10. (See paragraph 7-4-1-3.)
SENSOR S9 (DENSITOMETER/EXIT) reports to the slave MICRO on the DENSITOMETER BOARD.
•
The LED for this SENSOR is on the LIGHT SOURCE BOARD in the DENSITOMETER MODULE.
(See paragraph 7-4-1-3.)
Note
All SENSORS can also be checked via "Service WebLink". See paragraph 7-2-8.
