Well... pretty sure it's down to me buying a new mainboard. This printer will probably be down for a while. How can I keep the heads and the rest of the system in good condition since I probably won't be printing with it any time soon?

Ya I figured. Well, my electrical engineer friend and I dive into it this evening. Hopefully we can find the problem.

But really, I'd like to just fix the one I have... any way of knowing what blows up on the motherboard so that we can just repair the one we have?

Whoa. $1500! Bummer... Maybe it's time to upgrade to that HP L25500? :doh:

We replaced some chips on the head board, sounds like we still have damage to the main board though. My electrical engineer friend is going to take a look at it. However, if it comes down to it, is there a place that sells motherboards for the Mutoh Falcon? Or, is the a place that repairs...

Is yours a 60"? I'd be interested in a 60". An electrical engineer friend of mine helped me fix the fuse yesterday, and he thinks he tracked down the chips that I blew up when I removed the cables while it was on. I ordered the chips and they'll be here this morning. I hope it works! Shoot me...

Ok folks, here is what I got. These 2 things in the background with the nuts on them, I saw somewhere on the forum, but I don't remember where. So I thought I would get a reading on them as well. The left one doesn't read, so maybe that is the one that I blew up when I removed that cable?

I found the main board. I even found the fuses. However, I know I must have blown something else up when I removed the cable while the machine was on last night, causing it to dump only LC during the nozzle check. Anyone??

Or, is the head board the main board?

Does anyone know where the main board is located on this machine?

Crud. How do I go about finding out what I might have blown?

I did before this happened :doh: I had been turning it off, but when I went to fidget with those big cables I forgot to turn it off first. Then this happened. What did I do?

Here is the nozzle check from this morning. Just dumping ink, primarily LC, with a little bit of Magenta and squares of Yellow. This is after I tried re-attaching the cables again. Any ideas?

Anyone? Also, since messing with cables it seems to really gush the light cyan there : (

Thanks! So, I reconnected or snugged everything on the board in the attached image. And now I'm getting a solid blue line for my nozzle check :) Anything else I should check? Also, how do I make it stop printing a solid blue line as my nozzle check? Thanks! Andy

This printer has been printing like a dream all weak. My last print was last night. However, tonight, I get ready to do another print, and the nozzle check shows the whole left head missing. How can this be? I've tried several cleanings and I can't seem to get black, cyan and light magenta to...

Any ideas? I would like to start doing large queues, and right now I can't :(

Would you still use it as a regular sign on a vehicle? Just not a wrap?

Good to know! Wish they didn't advertise it as a wrap solution...

Thank you, how far under the flair did you wrap?
