Solutions

Diagnóstico rápido

Error E12 is identified when the scanner carriage fails to move properly during a scan or copy task. This is often accompanied by unusual grinding noises. Check if the lid closes firmly and ensure there are no obstructions on the glass.

Solución paso a paso

  1. Power cycle the printer by unplugging the power cord for 60 full seconds to discharge static energy.
  2. Check the USB cable; if the printer is connected via USB, a faulty cable can cause initialization failures.
  3. Perform a factory reset via the HP Smart app to clear temporary firmware lockouts.
  4. Clean the glass plate with a lint-free cloth and check that the track is free of any debris.

Prevención y mantenimiento

  • Perform test scans regularly to prevent the carriage track from drying out or seizing up.
  • Keep firmware updated via the HP Smart app to resolve communication bugs.
  • Avoid placing heavy objects on the scanner lid that may misalign the internal components.

Cuándo llamar a un técnico

If the scanner carriage makes grinding noises or remains unresponsive after a power reset, the flat cable (FPC) or the scanner motor may be damaged, requiring professional repair.
