Paper Feed Service Checks
Paper jam error indication during POST
FRU
Action
Fuser (exit sensor)
If the exit sensor flag, which is visible at the back of the fuser, is in any
position other than vertical, then the machine will display a paper jam.
Make sure the flag is operating freely.
Replace the fuser if the sensor is damaged.
Input/duplex sensor
Manual feed sensor
Make sure the input paper feed sensors are working properly. A stuck or
incorrectly installed sensor causes a paper jam indication.
Media picks but stops halfway through the machine
FRU
Action
Input/duplex sensors
(under print cartridge
assembly)
Input sensor (manual)
Stairway cables
Check the stairway cables to verify they are properly connected to the
engine board at connectors J500 and J501, and on the controller board at
connectors J26 and J27.
If they are properly connected verify continuity on both cables. If this fails
replace the cables.
Make sure the input sensors are working properly.
Check for a broken or stuck flag on the input sensors. Clear anything that
keeps the flags from rotating freely.
Make sure the cables are seated on the engine board at J27 (input/duplex
sensor) and J23 (manual input).
Check for +5Vdc on pin 2 and 5 at J27 on the engine board (input/duplex
sensors) and pin2 at J23 on he engine board (Input sensor). Voltages on
pins 1 and 4 at J27, and pin 1 at J23 should change as the flags intersect
with the sensor.
• If correct, then replace the input paper feed sensor.
• If these voltages are not correct, then replace the controller board.
• Check the pick tires. Clean or replace as necessary.
