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. Common replacement parts for this code: scanner assembly
- Common replacement parts for this code: scanner assembly (includes motor, image sensor, and cabling), scanner control PCB, encoder strip, ADF rollers, scanner ribbon cable.
- Replacing the entire scanner assembly is often more reliable than piecemeal repairs when the underlying fault is intermittent or when multiple scanner subcomponents show wear.
- Verify part numbers against the exact Xerox model and firmware level. Use official service guides for disassembly to avoid damaging plastic clips and connectors.
Final Verdict
Xerox Fault Code 043-343 is a medium-severity jam that signals a timing issue at the inverter exit. While it can temporarily halt production, it rarely requires a service call. A methodical clean of the inverter rollers and sensor flag resolves >80% of cases. For technicians, checking the actuator flag before replacing any motor saves hours. For end-users, keep roller cleaner on hand and learn to access the inverter cover – this code will become a minor nuisance rather than a major stop. Final Verdict Xerox Fault Code 043-343 is a
Without this feature, the device may enter an unrecoverable fault state, halting all printing and requiring a service call.
