Spent 6 hours getting everything up and running. Printer still hangs!!!! So I guess its not windows 7 after all. It is just this piece of junk printer in which I owe another 1 1/2 years on! Biggest piece of garbage ever. Ive spent more money trying to keep this thing going then to just buy another printer I think! Cant wait until it is paid off, it is then going to meet my friend Mr. Baseball Bat (office space style)......ROLAND FTW!!!!
You'll have to bear with me here because I know diddly squat about modern printing machines.
I've read & re-read your posts and something keeps nagging away... motion control.
We had a frustrating issue with a CNC router. Turn the machine on, run a small cutting job... happy days. Load up a full sheet of material and then run a big cutting job.... utter freakin nightmare... X axis jumping & grinding or simply flat out refusing to move in ANY direction.
I was utterly convinced that the problem lay with the computer, the software, the PCI motion control card or the data cable.. basically everything this side of the router. After spending hours fiddling around with new cables, reinstalling software the fault was still there.
In desperation I called my mate who fiddles around with printed circuit boards for a living. He traced the problem to a 25 pence component on the X axis drive board. Turns out that this particular component can start to fail and still work perfectly.... as long as you're running small jobs which don't allow the motion control card to reach normal operating temperature it will move the X motor perfectly. As soon as the card is up to normal temperature this component starts going bat $hit.... missed instructions, garbled transmissions etc.
I've worked around CNC cutting machinery for years and it never even crossed my mind that the weird and wonderful problem we had was related to the actual drive circuits. I assumed a motion control drive would either work or not work with no in between.. turns out this isn't the case.
I might be wrong but I think most digital printers use stepper motors & drives which means your drive system is essentially "dumb". When your printers on board computer is processing your print job it fires off commands to move the vinyl through the machine on the X axis & shove the print head across the vinyl in the Y axis. What it doesn't do and can't know is whether or not these commands actually translate into movement. Stepper motors don't send feedback data to the computer so there is just no way for your printer to know that the movement instructions it sends actually translate into physical travel on X & Y.
I noticed you mention that the screen on your computer doesn't freeze or drop out but tells you the job has finished printing... this could be explained by a motion control problem. Your printer is tellling itself to move in X & Y and as far as it's concerned it is moving because the data has been sent. Without servo style feedback it can't check whether or not it is actually moving so it just assumes it is and tells you it's finished the print job once the last line of commands have been executed.
On all our machinery the motion controls are on external cards so they're easy to check.. yours are probably embedded onto the main board which you say is new but might be reconditioned or simply not tested for the motion control side of things. I'd be asking the mainboard supplier some serious questions... has he had this board in the same model of printer and used it to drive X & Y over a distance of say 2.5m? Will he swap the board for a second which you can test? Do you have the old one? If you put it into the printer will the damn thing move properly over long distances on X & Y?
Hope this helps.
