Xerox Fault Code 043-343 Jun 2026

Power the machine back on and observe if the code clears during the initialization sequence. Step 2: Inspect and Reseat the Imaging Units

A YMC Link Sensor detection error was detected (Mismatch of print mode and YMC Link Sensor driven state register information). Fault Code 043-345, 043-346: Drum Motor Failure

Xerox Fault Code 043-343 is a specific and well-documented error related to your printer's drive system and YMC Link Sensor. While it can be alarming, the issue is often rooted in a few mechanical or electrical components. By following the systematic diagnostic approach outlined above, you can quickly identify whether the problem requires a simple repair or a professional replacement.

Reinstall everything firmly, ensuring all latches click into place. Advanced Technical Solutions Xerox Fault Code 043-343

The mechanism meant to drive the link bar is not functioning.

Do not simply press the power button. A true hardware reset can sometimes clear transient errors.

Look directly at the main drive assembly gear track (located on the left/rear side of the machine). Check for stripped teeth, cracked plastic cogs, or heavy debris stalling rotation. Power the machine back on and observe if

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.

: Inspect the connection between the YMC link solenoid (P/J203) and the Drive PWB (P/J413) for signs of damage or open circuits.

Follow these diagnostic steps sequentially to isolate and resolve the issue. Step 1: Perform a Hard Power Cycle While it can be alarming, the issue is

Below is a comprehensive guide to understanding what this code means, how to troubleshoot it, and when to call a professional technician. What Does Fault Code 043-343 Mean?

Check the transfer area for paper jams or debris, especially around the transfer belt area. 2. Technical Diagnostics (Service Level) If the error persists, the issue is likely internal.

If the above inspections do not reveal a clear issue, a systematic replacement of parts is the next logical step. Based on the service manual, the recommended replacement order is:

Shut down the printer and disconnect the power cord for safety.
