Inspect the paper path for any jams or debris that might be interfering with sensor movement.
A defective fuser unit, drum cartridge, or transfer belt is pulling too much power. Xerox Fault Code 043-343
If the link bar fails to move during diagnostics, the mechanical system is failing: Locate the on the main drive assembly.
Authorized technicians can pinpoint the hardware failure using Xerox's built-in . Enter the diagnostics menu on the machine interface.
The fuser operates at extremely high temperatures (over 180°C / 356°F). Always power off the machine and wait at least 20–30 minutes for the fuser to cool completely before attempting any physical inspection. | Step | Action | Success Indicator |
The "YMC Link" refers to a mechanical assembly driven by a solenoid and monitored by a dedicated sensor. Its primary job is to lift or lower the internal components associated with the color drums depending on whether you are printing in color or black-and-white. The technical breakdown of the error includes:
Sometimes, the solution is less orthodox but effective. User forums and technician logs provide valuable field data:
