Question:

 I am seeking assistance to determine the necessary parts for my DTF printer (DTG Pro Fusion model based on a 1390 printer). Recently, the print head ceased spraying despite moving across the carriage normally. After investigating, I discovered white ink had contaminated the main board and ribbon cables. Post-cleanup, I replaced the main board, print head, and cables, but now the printer won’t power on, except at the rocker switch. Could there be a misconnection, or is something else at fault? Your advice on potential solutions or needed parts would be greatly appreciated.

Thank you for reaching out to us for assistance. At BCH Technologies, we appreciate your engagement and support, especially your interest in our YouTube channel. Your feedback is invaluable in enhancing our expertise and helping others with similar issues.

Here’s a detailed breakdown to help troubleshoot and potentially resolve the issues with your DTG Pro Fusion model DTF printer:

1. Check All Connections: Start by re-examining all the new and existing connections. Make sure that no connectors are loose and that all ribbon cables are properly aligned and fully seated. This includes checking the seating of the print head and ensuring all power connections are secure. Most of similar situations is that people didn't securely plug in the control panel's FFC. Model J's mainboard is kind of upside down for the printer, so it is possible to get knock loose during installation.
2. Inspect for Damage or Corrosion: Look for any signs of residual damage or corrosion on the board and cables, which could have been caused by the white ink spill. Even minimal residue can lead to significant electronic malfunctions.
3. Power Supply and Fuses: Check the functionality of the power supply unit (PSU) and inspect for any blown fuses on the main board or related power boards. These components are crucial for distributing power throughout the printer and can fail if exposed to contaminants. Test with Minimal Configuration: Reduce the printer to its basic components necessary for power-up. Make sure the mainboard is powered by testing the power input from the Power Supply. Then you can narrow down the problem to the mainboard. This approach can help isolate the faulty component by gradually reconnecting parts and monitoring the printer’s response.
4. Continuity Test: Use a multimeter to test the continuity of the ribbon cables and wiring harness, particularly those connected to the power distribution for the print head and carriage. This will help identify any hidden breaks or shorts.
5. Error Codes or Diagnostics: After the mainboard is powered up, use Epson's Adjustment program to check the error code. If your printer displays any error codes upon startup, refer to the user manual or manufacturer’s support to decode these messages. These could provide specific clues about internal errors or malfunctions.
6. If the printer is still now powering up but there is electricity sent to the mainboard, you will need to have the mainboard repaired or returned to the seller.
7. Consult the Service Manual: Acquiring the service manual for your printer model will offer comprehensive troubleshooting steps, diagrams, and part numbers, which are particularly useful for complex issues.
8. Technical Support and Forums: Consider seeking help from DTG Pro’s support team or exploring online forums dedicated to DTF printing. Such platforms can offer insights and solutions specific to your printer model.
9. Consider Professional Service: If these steps do not resolve the problem, it might be best to consult a professional repair service experienced with these specific types of printers.
