mainboard burning head? two error07's in a week

i have a complex issue.

1) i need the printer/main board properly diagnosed

2) i am wondering if there is a perimeter change that will allow the printer
to ignore the fourth head.

after an exhausting vacuum leak search in my printer (caused by weak cap top springs). i am now having electrical issues.

upon getting the printer going, i noticed a periodical wild over spray coming from the cyan head (running CMYKx2).

i attached a photo of this. also in the photo you can see a small amount of yellow overspray.

within about three days i get an error07 _ _ _ _ _ _ * _. that was an old abused head printing terribly so if figured as much.

put in an old proxy head that prints decent (always missing a few lines despite weeks of soaking away from the machine). within about four days i get an error07 _ _ _ _ _ _ _ *. (and i did get the wild overspray from the yellow head about 30 minutes before it died doing a small proof)

i data swap, and rotate the ribbons and the error remains at the same port of the same head.

seems to me that this thread has some similarities.

does anyone have some advice on how to keep from costing me another head? from the looks of the prior thread, even having the main board checked might not fix this.

this is the emergency part:

i have an emergency delivery/install on monday. haven't even started the piece. are there any proxy heads that i can buy off one of you guys in the houston area that will maybe allow the printer to limp through this project over the weekend? (probably fry the proxy head in a few days).

or,

is there a tech that can tell me some kind of exotic perimeter change that will cause the printer to ignore the fourth head of the printer? that would be awesome. the project only requires black, clear, and white which i print all of from the K head only.

 

bump.
