How to Fix: Bixolon SPP-R200 thermal printer - error light blinks when it detects black marker

The Bixolon SPP-R200 thermal printer is experiencing an error where the red light blinks when it detects the black marker, causing the print to stop. This issue affects one of two printers, and the problem persists even in test print mode or when using the feed button.

This frustrating issue can be particularly challenging for users who rely on the printer for printing tickets with a black marker. The good news is that troubleshooting steps are available to resolve this problem.

⚠️ Common Causes

• The primary cause of this error is likely due to a calibration or alignment issue with the printer's sensor. Over time, the sensor may become desensitized to the presence of the black marker, causing it to trigger incorrectly. This can be especially true if the paper used for printing has been in use for an extended period.
• Another possible cause could be a software-related issue, such as a faulty firmware or a misconfiguration in the printer's settings. However, this is less likely given that the second printer was able to auto-calibrate successfully.

✅ Best Solutions to Fix It

💡 Conclusion

To resolve the issue with the Bixolon SPP-R200 thermal printer's red light blinking when detecting the black marker, try the calibration and sensor alignment method first. If this fails, attempt a software reset and firmware update. If the problem persists, it may be worth contacting Bixolon support for further assistance.
