Xerox Fault Code 043-343 Guide

If all mechanical checks and wiring inspections are negative (no breaks, shorts, or obstructions), the fault is likely a failing electronic component. Xerox technical documentation provides a clear order for replacement:

Always start with the simplest fixes: clear the paper path, check the consumables for free movement, and perform a deep power reset.

The control board responsible for sending voltage and signals to the motor may be failing to deliver power.

: Turn the machine off using the power button, wait at least 10 seconds, and then turn it back on. Xerox Fault Code 043-343

Given the mechanical nature of the error, a systematic approach is necessary for a successful repair. Always power off and disconnect the machine before beginning any hands-on work for your safety.

A loose or broken connection between the sensor and the drive PWB (Printed Wiring Board). How to Fix Xerox Fault Code 043-343

If you are comfortable with hands-on repair: If all mechanical checks and wiring inspections are

If you have attempted the mechanical checks, verified the sensor circuits, and even performed a firmware update without success, the internal components have likely degraded. This is the point where officially recommends contacting a service representative. Replacing DRIVE PWBs or the ESS board requires specialized tools and knowledge of non-volatile memory (NVM) reinitialization, which can permanently damage the machine if done incorrectly.

If these basic steps fail, the issue is almost certainly mechanical. : Turn the machine off using the power

Before attempting a fix, it helps to understand why the error occurred:

Sometimes, transient electrical noise or a temporary logic glitch can trigger the fault.

Do not just press the power button. Turn the machine off at the control panel, flip the main power switch behind the door (if equipped), unplug the power cable from the wall outlet, and wait at least 60 seconds. Replug and power back on to see if the register clears.
