Hello,
I'm experiencing a printhead-related issue with my Canon TM-200 printer. The printer displays the error code EC21-2F53, which seems to indicate a problem with the printhead voltage (VH).
Troubleshooting Steps Taken:
✔️ I removed the faulty printhead from my TM-200 and installed it into another, fully functional TM-200 printer. The second printer also failed to recognize the printhead, showing a similar error.
✔️ I then installed a working printhead from the second printer into the one that originally had the error. It was detected without any issues, confirming that the printer itself is working fine.
✔️ I cleaned the printhead contacts (but not with water) and tried reinstalling it, but the error persists.
Conclusion:
Since the working printhead is recognized in both printers and the faulty one is not, it seems that the printhead itself is damaged.
Questions:
- Is there any known method to reset or repair a faulty printhead, or is replacement the only option?
- Could a firmware update cause this issue?
- Is this a common problem with Canon TM-200 printheads?
I would appreciate any advice or recommendations. Thanks in advance!
