Xerox Fault Code 043-343

If the motor cannot turn the internal components, it will trigger the error. You need to identify which component is binding. Turn off the printer.

Finding a cryptic error code on your Xerox printer can bring productivity to a screeching halt. If you’re seeing Fault Code 043-343 , you are likely dealing with a YMC Link Sensor Fail

In simpler terms, the printer attempted to switch between its drive modes and the sensor responsible for confirming the switch didn't report back correctly.

Xerox Fault Code 043-343: YMC Link Sensor Fail Report Fault code

The diagnostic and repair procedures for code 043-343 can be complex and require specific technical knowledge and genuine Xerox replacement parts. You should seek professional service if:

is a critical hardware communication error primarily found in Xerox VersaLink and WorkCentre series color printers. It indicates a YMC Link Sensor Fail If the motor cannot turn the internal components,

An engineer will enter the service diagnostics mode and run to initialize the first Bias Transfer Roller (BTR).

Run the specific diagnostic code for the or Dev Motor (refer to your specific Xerox model service manual for the exact chain-link numbers, often found under Section 4 of the service documentation). Finding a cryptic error code on your Xerox

Technically, the error is triggered when the printer's logic, as represented by the 'Print Mode', does not match the state reported by the 'YMC Link Sensor driven state register'. In simpler terms, the printer's computer is commanding a specific mechanical action, but the sensor is reporting that the action either didn't happen or is in the wrong position.

They will execute a component test (such as ) to manually apply voltage to the Main Motor.

Input the diagnostic command code to initialize the 1st BTR (Bias Transfer Roller).
