Call a technician. This is the resolution in my manual for the problem: "Defective or dirty encoder needs to be replaced. Call a technician."

Sorry! This thing has some sensors that do go bad on occasion.

Your Main Board (called a CMX) has failed. You can google
"PRINTRONIX 157450-991 PWB,CMX,V 5.5 40MHZ,EXCHANGE,P5000 "
For the part, but the part will require software either pre-loaded or you will have to get the file to load, ask about that before you purchase this or it will not work when you get it.

Sounds like a failing weld sensor. Clean it first its on the left side, you can see it when the ribbon is out. If that doesn't help replace it.

25 Encoder fail

1. The tractor encoder signal is faulty.
a. Clean any toner or paper dust out of the encoder sensor.
b. Inspect the tractor encoder wheel for damage. Replace it if necessary.
c. The encoder sensor is faulty. Replace the tractor encoder board or the entire tractor
d. The fuser drive clutch is slipping; replace it.
e. Replace the Engine Controller Board.
f. Replace the encoder cable.

�� Tractor Encoder. The Tractor Encoder Board has two optical sensors that sense the
1/8 inch and 1/16 inch slots in the Encoder Wheels. These pulses are sent to the Engine
Controller Board and are used to monitor and control print location and paper movement.

Remove the Tractor Encoder Cover by removing 1 Screw.
NOTE: Upon installation, the groove on the bottom of the Encoder Cover should
straddle the top of the left end of the Tractor Frame.
Left side of printer, just left of the tractor assy.

"Shuttle jam" see manual problem on Printronix line matrix P 500E printer

Verify that there is nothing clamped between the platen and the shuttle.

Last time I had this fault, it turned out to be a broken wire in the harness that connects the CMX board to the shuttle module.

Other possibilities include a failed shuttle or CMX board.
