Xerox Fault Code 043-343

Chronicle of Xerox Fault Code 043-343

Overview

Common Causes (Ranked by Frequency)

  1. Roller contamination or wear – Inverter rollers lose grip due to paper dust or worn rubber. This is the #1 cause.
  2. Actuator or sensor failure – The mechanical flag for the inverter exit sensor may be stuck or broken.
  3. Paper curl or stiffness – Heavy stock or curled paper fails to reach the sensor on time.
  4. Debris in paper path – Small scraps of paper or labels lodged behind the inverter unit.
  5. Drive gear damage – Less common, but stripped gears in the inverter drive assembly cause intermittent jams.

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. Xerox Fault Code 043-343

Automated remediation actions (one-click)

  • Soft reset of affected subsystems (commanded via firmware).
  • Run sensor recalibration routine.
  • Move carriage through full range at low speed to clear obstructions.
  • Flush and reinitialize related controllers.

3. Test Registration Clutch (Component Control)

  • Navigate to Component Control → DADF → Registration Clutch.
