Xerox Fault: Code 043-343

If you are comfortable, ensure the motor connectors are tight. Check for any visible wire damage. 💡 Root Causes

| 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

Xerox Fault Code 043-343 is a safety mechanism designed to protect the Ink Melt System from overfill damage. While often resolved by simple user maintenance (replacing the waste ink container), it can indicate deeper mechanical obstructions or sensor failures within the IMS. Through systematic diagnosis—starting with the waste container, moving to sensor checks, and ending with IMS replacement—technicians can restore functionality efficiently. If you are comfortable, ensure the motor connectors
