machine comes ready then immediately goes into calibration and never quits. Berst I could get from the events are 54.0f 1,2,3. This is a brand new machine out of warranty, 18 prints total on it. I tried three different set of carts in it. One brand new set. all show genuine on screen. Cleaned all the drum contacts. tried all the boards with one exception. I might not have tried an dc controller long enough to get a result as I was in a hurry to get done as I had 1 1/2 hour drive to go. No excuse. I thought maybe I gave it enough time to calibrate but then again maybe not. I got the boards from an identical machine there at customers office. It lays down the patches ok but never makes a decision to come ready. I changed the ETB as well. I am not so sure it has something to do with the etb wiring back to the dc controller. I also checked the connector pcb from the ETB to the dc controller. what the heck is going on? Do you think it is the dc controller?
