Xerox Fault Code 043-343: An Informative Review

Overview
Fault code 043-343 is a specific chain jam error on Xerox digital presses. It indicates that the paper has successfully passed through the registration rollers but has not triggered the Inverter Exit Sensor within the expected timing window. In simpler terms: the machine fed the paper, but the sensor at the exit of the inverter unit did not detect it on time—or at all.

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.
• Rollback last firmware update (if error detected post-update) — requires admin confirmation.

While a simple restart occasionally resolves a 043-343 error, it is often a signal that a mechanical component Xerox Fault Code 043-343

Inspect the internal path for any scraps of paper or debris that might be interfering with sensor movement. Verify Firmware: Soft reset of affected subsystems (commanded via firmware)

• The code often shows up after one of the following events:

  Xerox fault code indicates a YMC Link Sensor Fail , occurring when the printer detects a mismatch between the current print mode and the expected state of the Yellow, Magenta, and Cyan (YMC) link sensor. This error is primarily associated with the Xerox VersaLink series , including models like the C7000, C7020, C7025, and C7030. Technical Breakdown: Fault Code 043-343 Error Definition
