Initial issue
Status Indicator RAPs
8-164 POB Sensor
The POB Sensor did not detect paper after the Registration Clutch Energized.
Initial Actions
• Check condition and specification of the paper supply.
• Check for paper on the IBT.
• Check for obstructions in the paper feed path.
• Clean the POB Sensor.
• Check the 2nd BTR transmission gears for wear.
• Clean the Registration Roll and check for damage or wear.
