Common causes

  • 1Physical obstruction by paper scraps or loose labels in the print path.
  • 2Wear of the flat (flex) ribbon cable transmitting power to the carriage.
  • 3Accumulation of dried ink on the slide rail.
  • 4Carriage displacement motor failure due to power surges.

Solutions

Diagnóstico rápido

If the printer makes grinding noises at the sides while trying to print or stops right after starting, the 0x94 error is responsible. Inspect if the carriage is physically jammed against one side.

Solución paso a paso

  1. De-energize: Turn off and unplug. Hold the power button for a few seconds.
  2. Free movement: Gently move the cartridge carriage from end to end to rule out obstructions.
  3. Reboot: Reconnect and turn on. Let it complete the self-diagnostic cycle.
  4. Shaft cleaning: If the carriage seems heavy, a little technical silicone grease on the steel bar can smooth its operation.

Prevención y mantenimiento

Avoid jarring the equipment. Perform periodic cleaning of the loading area to prevent scraps of paper or dust from settling on the carriage slide shaft.

Cuándo llamar a un técnico

If after resetting and cleaning the shaft the printer still displays 0x94, the internal ribbon cable is damaged or the carriage motor has lost torque.

Frequently asked questions

This error usually indicates a communication problem with the printhead carriage sensors or a stepper motor fault, preventing the synchronization required to print.

If the error is 0x94, it is not a nozzle clogging issue but a logic or movement problem. Cleaning nozzles will not fix this technical fault.

Always use genuine Epson DURABrite inks to avoid sediment buildup that damages ink pressure sensors.

It depends on whether the fault is a loose cable or if the carriage motor has failed. A technician can quickly determine which one is at fault.
