Xerox Fault Code 043-343 [updated] Jun 2026

Because the fuser is responsible for melting toner onto paper using high heat and pressure, any deviation in its performance triggers an immediate safety shutdown.

Before executing deep hardware tests, clear residual charge or minor software glitches out of the system. the machine using the primary power switch. Unplug the main AC power cord from the wall outlet. Wait 2 minutes to let the capacitors fully discharge.

If you encounter this error on models like the Xerox VersaLink C7000 Series, follow these steps in order: 1. Basic Power Reset

The mechanism meant to drive the link bar is not functioning.

Gears, rollers, or transport belts are jammed or locked, preventing the motor from turning freely. Xerox Fault Code 043-343

Manually try to turn the gears on the fuser unit and the drum cartridges. They should rotate with some resistance, but they should not be completely locked.

If the link bar physically moves but the error persists, the sensor cannot read the movement: Locate the .
