Troubleshooting DTF L1800 Printer Power Button Issues: Step-by-Step Fixes

Question:

Why did the power button on my DTF L1800 printer stop working during printing, and how can I fix it? The rear power button for the temperature display still works, but the printhead power button in the front won’t turn on.

Answer:

To address your issue, the main power button on the DTF L1800 controls both the printer and the white ink management system. If the power button in the back (for the temperature display) still works but the front power button does not, it typically indicates a failure within the mainboard. Based on the symptoms, it’s likely that the printhead caused an overload or electrical short, damaging the mainboard and possibly affecting the FFC (Flat Flexible Cable) connections.

To fix this:

1. Inspect and Repair the Mainboard: The mainboard is the heart of your printer. When it fails, it can render the printer non-operational. You will need to either repair or replace it. At BCH Technologies, we offer mainboard repair services.

2. Check the Printhead: After the mainboard is repaired or replaced, it’s essential to test the printhead. The damaged printhead may have been the root cause of the failure. If you send us your mainboard for repair, we can also evaluate the printhead to determine whether it’s salvageable or needs replacement.

3. Examine and Replace the FFC Cables: Damaged or faulty FFC cables can also contribute to power issues. Carefully check for any visible signs of wear or damage and replace them if necessary.

Once these components are repaired or replaced, your printer should return to working order. If you’d like to proceed with a mainboard repair, feel free to contact us in advance at support@bchtechnologies.com. Including your printhead for diagnosis with your mainboard repair order can help us provide a quicker and more comprehensive evaluation.
