Toshiba B-EX6T3 E-HEAD OPEN Error: Fix Guide

The 'E-HEAD OPEN' error on the Toshiba B-EX6T3 indicates that the printhead sensor detects the pressure mechanism is not fully locked. This security feature halts printing to prevent damage to the thermal element. The most effective fix involves firmly re-locking the printhead lever to ensure the sensor registers a closed state.

Common causes

  • 1Adhesive residue blocking the printhead sensor.
  • 2Mechanical wear on the locking lever prevents sensor engagement.
  • 3Physical obstruction by misaligned labels on the roller.
  • 4Internal microswitch failure preventing detection of closed head.

Solutions

Diagnóstico rápido

The error appears on the LCD panel with a persistent alarm. Ensure the printhead lever is locked in the horizontal position. If the lever feels loose or won't click into place, a physical obstruction is likely preventing the closure.

Solución paso a paso

  1. Turn off the printer to ensure safety during the inspection.
  2. Release the lever by pulling it upwards completely.
  3. Clear any debris or adhesive buildup near the printhead contact area.
  4. Re-engage the lever firmly until you feel a secure, solid click.
  5. Turn on the printer and verify the message clears.

Prevención y mantenimiento

Regularly clean the platen roller using isopropyl alcohol to prevent dust buildup. Never force the head lever; if there is resistance, check for jammed labels. Perform routine maintenance every 50,000 prints.

Cuándo llamar a un técnico

If the error persists despite correct physical closure, the internal microswitch or sensor may be faulty. Contact professional support if you encounter mechanical resistance or abnormal grinding noises.
