Common causes

  • 1Hidden paper obstruction impeding the drive rollers.
  • 2Toner dust buildup affecting the engine sensor calibration.
  • 3Insufficient electrical power supply preventing motor initialization.
  • 4Mechanical wear on the cartridge gear interface.

Solutions

Diagnóstico rápido

The 950 error is characterized by the machine freezing during the startup sequence or midway through a print job. Before assuming a motherboard failure, visually inspect the interior for any paper residue or foreign objects.

Solución paso a paso

  1. Power Cycle: Disconnect the printer from the power source for 60 seconds to allow the volatile memory and motor controller to reset.
  2. Inspect Path: Open the front cover and rear exit door to clear any debris or crumpled paper.
  3. Toner Check: Remove and reinstall the toner cartridge to ensure it is not applying excessive pressure to the drive gear.
  4. Reboot: Plug the printer directly into a wall outlet, avoiding power strips, and perform a warm boot.

Prevención y mantenimiento

Keep the printer in a clean, temperature-controlled environment to prevent excessive dust accumulation. Use genuine Lexmark toners to ensure optimal weight and mechanical clearance. Clean the rollers with a lint-free cloth every 90 days to prevent traction loss.

Cuándo llamar a un técnico

If the machine emits a grinding sound or the error returns immediately after a hard reset, the internal gears or the motor assembly itself may have suffered permanent physical damage.
