Xerox Fault Code 043-343 ((exclusive)) Instant
Reconnect the power and restart the device to see if the code clears. 2. Reseat Drum Cartridges
Wait at least 60 seconds to allow the internal capacitors to drain completely.
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. Xerox Fault Code 043-343
Understanding Xerox Fault Code 043-343: Causes, Symptoms, and Fixes
Xerox fusers are consumable items with a limited lifespan (often 200,000 to 500,000 pages). As the unit ages, rollers degrade, bearings wear out, and lubricants dry up. When the PM (Preventive Maintenance) counter exceeds the limit, the machine may intentionally lock down with a code like 043-343 to prevent fire or print quality disasters. Reconnect the power and restart the device to
Sometimes, a temporary power surge or data glitch causes a false error signal.
