Solutions

Diagnóstico rápido

The E1 error is triggered when the printer fails to register the paper size correctly. Check the front control panel: if the error light is flashing, it confirms the unit is experiencing a feed mismatch.

Solución paso a paso

  1. Clear the input tray and ensure no misaligned sheets are causing sensor confusion.
  2. Adjust the width guides to ensure they fit the paper stock snugly without bending it.
  3. Check print settings in your PC software to ensure they match the physical paper size (e.g., A4 or Letter).
  4. Power cycle the unit by unplugging it for 30 seconds to reset the internal error buffer.

Prevención y mantenimiento

Use standard 75-90 g/m² paper to keep the feed mechanisms clean. Keeping the input tray free of dust helps the sensors register correctly. Using genuine HP 44A toner prevents internal contamination.

Cuándo llamar a un técnico

If the E1 message remains active after a full reset and checking physical alignment, the internal paper sensor may be faulty and requires professional servicing.
