Question: My DTF L1800 faced a short from the printhead, leading me to replace the transistors on the motherboard. After installing a new printhead and turning it on, the printer ran a cleaning cycle for 1 minute then shut off and won’t power back on. Can I send only the motherboard to you for repairs, and what would the cost be?

Answer: We're sorry to hear about the trouble you've encountered with your DTF L1800 printer. At BCH Technologies, we do offer a specialized repair service for situations just like yours.

For mainboard repairs, specifically for models like the L1800, you can access detailed service information via this link: https://bchtechnologies.com/fast-track-mainboard-repair-l1800-xp-15000-et-15000-wf-7610-7620-wf-7110-wf-7710-7720-et-8550-et-2720-et-2750printer-mainboard-formatter-board-motherboard-troubleshooting-and-repair/. Repair times typically range from 2-3 weeks, dependent upon the specific issues encountered with your board.

Given the symptoms you described, it's also advisable to check the FFC (Flat Flexible Cable) for any issues and ensure that the replacement printhead is functioning correctly. It's possible that the issue with the printhead may have affected the power bridge, specifically component Q601, and potentially damaged other nearby components like capacitors. Also, I recommend do not do Power Cleaning or Ink Charging (from Epson's Adjustment Program) with this model, as it often damage the printheads and mainboards.

Please be aware, the repair cost listed on our website covers labor only; parts are additional. When sending in a mainboard or component for repair, it's important to note that the service will focus solely on the requested repair. If there are underlying issues with other parts of the printer, they may immediately impact the newly repaired component.
