Common causes

  • 1Dried ink crust causing pin blockage.
  • 2Heavy strain from dry, exhausted ink ribbons.
  • 3Worn data ribbon cable leading to intermittent signals.
  • 4Failed internal solenoid in the print head block.

Solutions

Diagnóstico rápido

The error E-Head is accompanied by a warning buzzer. Check if the print head is physically blocked by dried ink crust or paper fragments, which are common causes for solenoid failure.

Solución paso a paso

  1. Unplug the Printer to ensure safety while accessing the carriage.
  2. Remove Ribbon and inspect the print head surface for debris.
  3. Clean the Pins carefully using high-grade alcohol to dissolve ink residue.
  4. Check Cables for loose connections or wear that could interrupt signal transmission.

Prevención y mantenimiento

Lubricating the carriage rail and replacing ink ribbons before they become bone-dry is essential to the life of the head. Avoid heavy paper stock if the printer is struggling to strike it.

Cuándo llamar a un técnico

If the head is cleaned and reconnected but still reports E-Head, an internal solenoid might be burned out, necessitating professional replacement.

Frequently asked questions

The E-Head error signals a communication or overheating issue with the print head pins.

Cleaning often helps, but if pins are physically broken, replacement is required.

It uses DPK-series ribbons. Using old ribbons can strain the head mechanism.

Lubricate the carriage rails every 6 months to prevent friction-based errors.
