Gp 6.2.5 Sensors Check - GBC StreamPunch Ultra Service Manual

GP 6.2.5 SENSORS Check
A sensor can fail in two modes:
• Failed in High state: Machine thinks there is no sheet even
when a sheet is present. In this mode, the LCD will always show
"0" for that sensor, and will not go to "1" when a sheet is present.
• Failed in Low state: The converse of the above. "PAPER
JAM...." message will be seen on LCD.
It is unlikely for a sensor to fail in a Low state. Therefore a bad sensor will
most likely not give a "PAPER JAM..." message.
When there is "Paper Jam..." it is most likely because there is a
sheet/piece of paper, or paper dust collecting over the sensor.
Procedure
Do the following to check the status of any of the sensors.
The Sensors feature allows you to view the state of each of the 29
sensors to the StreamPunch Ultra/Ultra MP.
Cover each sensor to check if the sensor status changes from "0" to "1"".
• 0 means the sensor is open.
• 1 means the sensor is covered.
