Troubleshooting ACHI 1390 DTF Printer Shutdown and White Ink Transparency Issues

Question:
I purchased an ACHI 1390 DTF printer eight months ago and have struggled with ongoing issues. Recently, I noticed the white ink for the powder was turning transparent during a print job. The problem persisted despite running several head cleanings and checking the waste tank. I manually cleaned the printhead using DTF ink cleaner and reassembled it carefully. However, after running a few test passes, the printer shut down—no lights, no sounds, and no response except for the power light on the back. I tested the F1 fuse, and it passed continuity, but I’m at a loss now. Could this be a mainboard issue, and do you sell mainboards for this model?

Please don't reassemble the printhead while still slightly wet. Your diagnostic steps were excellent till the point of reassembling a wet printhead. It can create electrical problems in the printer’s system. Since the printer can turn on, based on your description, the issue is not with its F1 fuse, as this would only affect its ability to print and not turn on. The problem is probably not with the standard mains receptacles but with the printer’s mainboard or associated transistors.
The ACHI 1390 printers can require specific modifications to remain reliable for long-term DTF use. Cleaning the printhead using only the printer's cleaning function is often insufficient. For your current issue, I think you should check the transistors on the mainboard. You can follow the guidance in my video for newer 1390 boards (watch here: https://youtu.be/LVNDpBGDTK8?si=xMIl33QFTTqoKEy2) or the process outlined in my L1800 repair video, which applies to the 1390 model as well (watch here https://youtu.be/6DlKiaZPGRg?si=MdS2102SAO4zag6A).
Printer problems like this can be challenging since repairs are often hands-on.
