Think you will find it has more to do with MS Service Pack 3, which can't be un-installed... Just my opinion... If so, then you burnt some bridges...
Nope, happened on my Mac for years as well. The other day I hooked back up to my Mac that I ran the printer on for years (which did it as well) and sure enough it stalled. I had the printer hooked up to 3 different computers..two PC's and one Mac. No change whatsoever and all computers had different programs, configurations, etc. Everything computer related was ruled out.
I have the mainboard installed but haven't tested it yet as the ink fill ran out my LC so waiting on the new inks. Will update when I know.
As for burning bridges...I have two companies still willing to help me out who have good customer support. They want to resolve the issue and get me back up and running. They understand I was upset the situation was prolonged since 2005 and that I was just looking for some answers after so long. I was just one case that got sweeped under the rug and I do put that blame on myself as well for not following up more thoroughly. But I appreciate their help and am grateful they were willing to help me out in my time of need. Thanks to Mutoh and Signwarehouse. They were great.
As for those that came on here and were willing to help me out and share some knowledge on their free time I appreciate them as well.
OH..forgot to clear some things up as well. In my previous post I said that the board was not replaced after the calgraph tech adjusted the voltage and replaced the board. I was wrong. In the service bulletin from mutoh in regards to adjusting the voltage there is no change in main boards made. It's just a matter of adjusting the voltage. No mainboards are suppose to be swapped out. I apologize for my misunderstanding. I didn't know that information fully before I posted. I am not even sure my problems persisted from this occurrence only based on my speculation.
