Lexmark MC3426i Error 942.00: Motor Failure Fix

The Lexmark MC3426i error 942.00 is a transport motor fault that completely stops machine operation to prevent mechanical damage. This error occurs when the main board detects that the motor is not reaching the expected RPM or presents a mechanical block at the shaft. It is a serious alert that usually requires deep cleaning or repair of internal components.

Common causes

  • 1Physical blockage due to internally jammed paper debris.
  • 2Premature wear of transport motor bushings.
  • 3Electronic failure in motor power supply on the main PCB.
  • 4Overload due to dirty or clumped-up rollers.

Solutions

Diagnostic Check

If the machine stops with error 942.00 when attempting to print and emits a faint strain noise, an obstacle in the paper path or a jammed internal component is almost certainly to blame.

Step-by-step Solution

  1. Disconnect the power cable immediately.
  2. Remove all consumables to release tension on the rollers.
  3. Meticulously check the paper path for torn pieces of paper blocking the rollers.
  4. Reconnect and check if the motor performs its startup cycle correctly.

Prevention and Maintenance

Do not force the paper tray and always use the recommended paper weight. Paper dust accumulation on the rollers causes increased resistance that eventually leads to motor failures.

When to Call a Technician

If after checking the paper path error 942.00 continues, the motor has lost its torque or the control driver on the main board is damaged.

Frequently asked questions

The 942.00 code indicates a critical movement error in the main transport motor, usually caused by a physical blockage.

Turn off the equipment, verify there are no paper obstructions along the path, and restart the system after 5 minutes.

Poorly inserted toner can cause mechanical resistance, but the 942.00 error is usually deeper in the transport system.

If the error persists after clearing the paper path, it is likely that the motor requires professional technical review.
