Need Help Mutoh VJ1204 New printhead zero nozzle

[oldcaliprinting]

Just installed a new printhead on a Mutoh 1204, the first time I installed the head I received the dreaded e075err head cable error. I swapped out print head cables but these were longer than the original. I was able to clear the error.
Now the issue seems that I can not get any color to fire on the nozzle check at all. I tried doing a little and normal charge on the ink. Ink is flowing through the capping station and into the waste pad.
The only thing I can think of is it's still the head cables?

The head cable error means there was a short and shorts blow fuses. You need a new fuse on the main board. It's a 750mA 125V quick blow fuse. If you are lucky, you have a later version of the 1204 which has a sockets fuse in which case you can just pop a new on in. If it's older though, you will have to solder.

Thanks for the info. So the fuse would cause the nozzles to not fire even though I am getting no errors now?

Yup. To the printer, everything is working perfectly. It just doesn't know that the signal is not making it all the way to the head.

Took the board to the local cellphone repair since I didnt have the tools. Tested ok, wired the board back up and now I just get Red lights and no power to the display. Reading from left to right 2 reds 2 blank the rest red. Also, LD1 is red, and I get an LD1 flashing red on the next board over. I am ready to roll this thing into the street.

Got er running!!! Thanks to the guys at Solvent Inkjet for all the support. They recommended pulling out the memory stick, blowing some compressed air. Came right back up. Did a little charge and boom 100% nozzle. Beef Jerky time.
