Xerox Fault Code 043-343 -

: If the sensor fails to toggle during diagnostic testing, it must be replaced. 5. Safety Warning

Look closely for crumpled paper, labels, or foreign objects.

Plug the cord back directly into the wall (avoid surge protectors for this test). Power the machine back on. 2. Inspect for Media Jams and Obstructions

Wiring harnesses connecting the Main Motor to the Motor Drive Board or the Main Controller Logic (ESS) Board may be loose, pinched, or damaged.

If a new motor does not resolve the issue, the circuit on the MCU board that regulates motor voltage has likely failed, requiring a board replacement. Xerox Fault Code 043-343

Pull out any stuck sheets gently using both hands to avoid tearing.

If these steps do not clear the code, it may indicate a mechanical failure of the or the motor driving it, which typically requires a technician to replace the faulty component.

The error occurs when the printer's logic controller detects that the YMC Link Sensor is not in the correct position for the requested task.

The problem likely lies with the YMC Link Solenoid or its connection to the Drive PWB . Fault Code 043-343: YMC Link Sensor Fail - Xerox Support : If the sensor fails to toggle during

If basic troubleshooting fails, the problem lies deeper within the hardware. A service technician will typically take the following technical steps to resolve the code: 1. Component Diagnostics (CE Mode)

: The optical sensor itself has failed, or its lens is obscured by stray toner dust.

Technicians often refer to this error in the context of the "Marble" and "Marble 3" series platforms, which include models like the C2265 and C2263 .

Plug the cord directly into the wall (avoid extension cords or overloaded surge protectors). Power the machine back on. Plug the cord back directly into the wall

The IMS operates at high temperatures (>100°C). Service should only be performed by qualified personnel.

When the gear moves but the system triggers the 043-343 fault, the printer is mechanically moving but the tracking eye cannot confirm it.

This is the most common hardware solution. The assembly usually contains the motor, its immediate drive gear, and a small dedicated bracket.
