Xerox Fault Code 043-343

Before the error code appears, operators might notice one or more of the following symptoms:

Understanding why this error happens can help you determine whether you can fix it manually or if you need to order replacement parts.

Sometimes, electronic control units misread sensor data. A complete power cycle can clear temporary faults.

Essentially, the machine's software and its internal hardware components are communicating conflicting information about whether the color drive is engaged or disengaged. Recommended Troubleshooting Steps Xerox Fault Code 043-343

Manually check the physical drive gears on the drive assembly for cracked, missing, or heavily worn teeth.

Plug the cord directly back into the wall (avoid extension cords or surge protectors for this test). Turn the printer back on and check if the code returns. Step 2: Inspect the Paper Path for Jams A tiny fragment of paper can easily jam the gear assembly. Open all side doors, front covers, and paper trays.

Verify the electrical path between the YMC link sensor (P/J108) and the drive PWB (P/J407) . Check for crimped lines or broken pins. This public link is valid for 7 days
