Xerox Fault: Code 043-343

Xerox fault code indicates a YMC Link Sensor Fail , meaning the printer has detected a mismatch between the current print mode and the operational state of the sensor that manages the Yellow, Magenta, and Cyan (YMC) link. This error typically halts all printing operations and may require technical intervention if a simple power cycle does not resolve it. Common Causes of Fault Code 043-343

| Component | Role | |-----------|------| | | A jam where paper is still present in the paper path when it shouldn't be, or missing when expected. | | 043 | Subsystem: Paper transport / Inverter. | | 343 | Specific fault: Inverter Exit Sensor (Sens 3) timing failure. | Xerox Fault Code 043-343

: Turn the machine off using the power button, wait at least 10 seconds, and then turn it back on. Xerox fault code indicates a YMC Link Sensor

Ensure that all vents on the sides and rear of the machine are unobstructed. | | 043 | Subsystem: Paper transport / Inverter

This code is most commonly associated with the series, the Versant 80/180/2100 series, and similar engines using a short paper path inverter for duplex printing or face-up output.
