Question:
I’ve been following your YouTube videos on fixing DTF printers, but I’m facing a significant issue with my Epson L1800. The printhead was clogged, and I used an ultrasonic cleaner to fix it. After reinstalling the printhead, the printer started acting up. It powered off mid-print and won’t turn on again. The button on the back lights up, but nothing else happens. Could you advise me on what might be wrong and what I need to purchase to repair it?
Answer:
Thank you for contacting us at BCH Technologies. I appreciate your support, particularly with our YouTube channel (https://youtube.com/@bchtechnologies). Your feedback is invaluable in helping us improve and expand our resources.
I apologize for the delay in addressing your concern. I know how urgent printer issues can be. I've carefully considered your issue to provide you with the most thorough and accurate advice, and I hope to offer detailed guidance to get your printer back up and running.
From the symptoms you’ve described, it seems likely that the damaged printhead caused a short circuit that affected the printer’s mainboard. The FFC (Flat Flexible Cables) connecting the printhead to the mainboard may have also been compromised. This is common when a malfunctioning printhead is used in the printer.
Important Note:
Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. While we cannot provide detailed remote troubleshooting or repair advice, we offer an in-person evaluation and repair service at our local diagnostic facility (https://bchtechnologies.com/printer-repair-service). Just so you know, this service operates on a first-come, first-served basis and may have a wait time of several weeks.
If you prefer to troubleshoot independently, I recommend exploring our YouTube channel (https://youtube.com/@bchtechnologies) for relevant repair tutorials. Use the search bar to find specific videos; YouTube may even suggest helpful resources from other creators.
Thank you once again for contacting us. We appreciate your trust in BCH Technologies and hope this guidance helps you get your printer back in working condition. Please let us know if you have further questions or need additional assistance!

Understanding the Issue: Printhead and Mainboard Damage
When using an ultrasonic cleaner, it’s important to note that only the top manifold of the printhead should be cleaned, not the entire printhead. Immersing the complete printhead in an ultrasonic cleaner can irreparably damage it.From the symptoms you’ve described, it seems likely that the damaged printhead caused a short circuit that affected the printer’s mainboard. The FFC (Flat Flexible Cables) connecting the printhead to the mainboard may have also been compromised. This is common when a malfunctioning printhead is used in the printer.
Steps to Diagnose and Repair Your Printer
-
Check the White Ink Management System
- The Epson L1800’s power system is split between the printer and the white ink management systems. Even if the printer’s mainboard has failed, the white ink management system should still be operational. Verify if the white ink agitator or circulation pump is working to rule out total power failure.
-
Inspect the Mainboard
- Open the printer and inspect the mainboard for visible signs of damage, such as burnt components, blown capacitors, or scorch marks.
-
Test the FFC Cables
- Damaged or improperly connected FFC cables can prevent the printer from powering on or operating correctly. Check for bent pins, tears, or other signs of wear on the wires.
-
Replace Necessary Components
- If the mainboard is damaged, it will need to be replaced. Could you make sure the replacement is compatible with the Epson L1800 model?
- Replace the FFC cables if there are any visible issues. These are critical for proper communication between the printhead and mainboard.
-
Install a New Printhead
- Since the previous printhead may have caused the issue, replacing it with a new printhead is essential to prevent further damage to the repaired or replaced mainboard.
Preventing Future Issues
Once the printer is operational again, follow these best practices:- Avoid Long Periods of Inactivity: Regularly print test pages to keep the ink flowing and prevent clogs.
- Proper Cleaning Techniques: Use ultrasonic cleaners only on specific parts like the top manifold, and avoid immersing sensitive components.
- Monitor White Ink Management: If using DTF inks, keep the white ink management system clean and operational, as white ink tends to clog more frequently.
