VJ-1624 Main Board replacement

[GatorTPK]

I have VJ-1624 that will not print anything including the nozzle check. The owner had attempted to fix the printer and accidentally reconnected the print head data cables while it was still powered on.
I have replaced the print head, head data cables (Head FFC - DG-42385), CR Board, and Dampers (OEM Valve Head Assy - DG-41543), still no ink is printed. Ink appears on the capping station when running a cleaning cycle. Ink flows well.

The only left I can think of replacing now is the main board. The service manual says I need to use MUTOH Service Assistance Software. Is the software absolutely needed? I have a working main board from a VJ-1324 that is the same part as needed in the VJ-1624.

Any other possible solutions would be great!

Thanks in advance for any help you may have!

Did you check printhead fuses on the mainboard?
You can not use mainboard from VJ1324 on VJ1624 because it impossible to reprogram it. It will be bainboard for VJ1324 only forever.

Thank you for the excellent info! I see “The MAIN board-unique adjustment parameters cannot be erased or modified” now.

I haven’t seen the main board physically and didn’t see any indication of fuses yet. I’ll look for them!

Try to look around black radiators.

The 2.5 amp fuses on the main board are fine, but the 750mA fuse is bad! That’s the print head fuse. I ordered a few of them. Thanks Ucma!
