Xerox Fault Code 043-343 • Fresh
is a critical error message that typically appears on the control panels of mid-to-high-volume Xerox printers and multifunction devices (MFDs), particularly within the Color 550/560/570 series, the Versant 80/180 series, and the D95/D110/D125 production printers. While less common on desktop units, encountering this code generally indicates a hardware-level malfunction that halts all printing operations.
Reinstall everything firmly, ensuring all latches click into place. Advanced Technical Solutions
Turn off the main power switch inside the front door or on the back of the machine. Disconnect the power cord from the wall outlet.
The main logic board, usually the final component to replace. Commonly Affected Models VersaLink Series: C7000, C7020, C7025, C7030, C7120, C7125, C7130.

Fault Code 043-343: YMC Link Sensor Fail - Xerox Support Xerox Fault Code 043-343
When this error occurs, it means the printer's controller has detected a mismatch between the current print mode and the state of the YMC Link Sensor driven state register Xwktech . Essentially, the printer tried to move the color mechanism, but the sensor didn't report that the movement was completed, or it reported a conflicting status. Typical Causes
Common causes:
The sequence of events leading to 043-343: is a critical error message that typically appears
Damage or excessive wear to the drive assembly gears.
Inspect the internal path for any scraps of paper or debris that might be interfering with sensor movement. :
: A discrepancy between the printer's software (register information) and the physical state of the YMC link sensor. Advanced Technical Solutions Turn off the main power
A failing YMC link solenoid, a dead link sensor, worn-out drive assembly gears, or a failing Drive Printed Circuit Board (PWB). Phase 1: Basic Troubleshooting (User-Level)
Manually check the physical drive gears on the drive assembly for cracked, missing, or heavily worn teeth.
