Solutions

Diagnóstico rápido

The 0x9d error code relates specifically to the printhead's operational status. If you see this on the screen, refrain from repeated print attempts and instead check for missing colors in a nozzle check pattern, which confirms the scope of the issue.

Solución paso a paso

  1. Head Cleaning: Use the 'Maintenance' section on the printer's display to run a comprehensive head cleaning cycle.
  2. Check Supplies: Ensure your ink supply packs (T02A) are correctly locked into their designated bays.
  3. Power Cycle: Perform a deep power reset by turning off the unit and leaving it unplugged for several minutes.
  4. Nozzle Check: Always print a nozzle check pattern after cleaning to verify the resolution of the fault.

Prevención y mantenimiento

Regular use is the best prevention. The printhead system is designed to perform auto-maintenance; leaving the unit in standby (instead of powering it off completely daily) allows these background processes to function. Stick to original ink supplies to avoid chemical compatibility issues.

Cuándo llamar a un técnico

If the error 0x9d persists after three cleaning cycles or you encounter recurring streaks, the printhead might have reached its service life or requires specialized alignment.
