12-102 H Transport Entrance Sensor Off

Paper did not deactuate the H Transport Entrance Sensor.
Initial Actions
• Check condition and specification of the paper supply.
• Check for obstructions in the paper feed path.
• Clean the H Transport Belt and check for wear.
• Check the Guides on the H Transport Cover for damage, wear or faulty installation.
Procedure
Open the H Transport Cover (PL 17.3). Check H Transport Belts, H Transport Belt Drive Rolls,
and Guides on H Transport Cover for installation or damage problems
components are good.
