The E1 error flashes on the printer display. If there is no visible jam, it is often a software-to-hardware communication error regarding the paper size settings in your print driver.

Solución paso a paso

  1. Check for obstructions: Open the access door and remove any debris or jammed paper.
  2. Align paper guides: Ensure the input tray guides fit the paper width snugly without bending it.
  3. Cancel current job: Press the 'Cancel' button to clear the pending task.
  4. Power cycle: Unplug the unit for 60 seconds to reset the sensor state.

Prevención y mantenimiento
