Heres a video of the problem. Diamondback 6/8 Printing Problem (http://www.youtube.com/watch?v=uxKaM2EmGjk#ws)

is it the 1 head? or all of them?
-
Where is that air leak coming from?
-
I know nothing of this... but I do have an air cylinder sitting on my desk.
It almost seems like one of the valves isn't opening to let the air to escape... so it pulls a vacuum on the other side and then snaps back.
I know that doesn't help solve anything but someone else might know better of what to look for or do to test that theory out. Maybe disconnect the line that pushes the cylinder back in and see what it does (should extend with ease and stay there).
-
that shouldn't cause the head to shuttle back mid stroke I wouldn't think.

If it has a vacuum on the other side then it will pull against it till it can't go any more (might be about mid stroke) then when that other side's valve releases to let the head go back it springs back to a neutral state of pressure on the vacuum side.

Again Mac valve........you need to go to M&R forums for a more detailed explanation.
-
I'm not questioning you Tony... just talking out of my a$$ for MK and myself to hear myself talk. ;)
-
Only one head does it. I called M&R and they said it was the sensor but I bought it and put it on and it was not the sensor.
-
No prob.....try locating it under the machine. You can activate it by pushing the white button on top with a phillips head screwdriver. More than likely it is sticking. Sometimes a dab of oil will free it up or it may need replacing. The chaps over at the blue site can give you more professional advice though.

May I suggest some more gymnastics?
-
mac valve was my guess if it was a single head. it's either sticking(not likely) or the electrical part of it has failed and won't allow it to open and shut properly. Like tony said, push the white button in and it will flood, let go and it prints...simple.

Don't be jealous because I still got it in me, old man!
-
The reason tony said mac valve is because you can hear a air leak.. its stuck probably due to water in the lines. usually pushing the release may clear it out. a bad prox will act in the same manner but thats not likely the problem..

At 35, you should be in your prime nowadays, with lifespan kissing 90.
Do I miss the health of youth, without the aches and pain that seem to plague us in their sixties? A little
Do I miss the exuberance and accompanying foolishness of my thirties? nope. I have my own exuberance and foolishness tailored for my current age ;D
Do I appreciate the knowledge and wisdom of knowing that I'm not that wise? You betcha. ;D
Am I smart enough to not attempt more than I am physically capable of? Usually, but at least when I do, both I and my wife lay there with grins on our faces for a while. :P

Like trying to play two rounds of canasta in one "evening". :p

I think you may of changed the front prox and it may be the back prox. Our service manager left you a pm to call him to verify.
-
doesn't explain the air leak, but it would freak if it thought the head never left the station

you are correct this does not explain the air leak. That may be the cylinder but this problem is related to the prox or valve. In my opinion its the prox.
-
somehow I don't trust your opinion. ;D
Just kidding.
-
I know I am over analyzing it but that leak does not sound like its running through a valve. It does not have the same tone. That sounds like a line or a cylinder that is leaking. Let us know what it is. My money is on the valve or sensor. Should be a quick trouble shoot.
-
My guess is a shorted prox... :o '
Not sure if the D-Back has one or two...?
Saw the same problem on an old Trident SVX, and that was the issue... 8)
-
somehow I don't trust your opinion. ;D
Just kidding.
Sometimes I don't trust my own judgement either but I would
almost bet its the prox. LOL!
-
Thank you everyone for your suggestions. I talked with M&R on the phone for a long time this morning and found the problem. My knucklehead Press Operator turned on Flocker on the head while he was trying to move the squeegy forward, that is why it would not print. What the Flock, at least it is working again.
Thanks
Pete
-
That was my next guess. ;D
One of my favorite things is when somebody cranks the squeegee speed all the way down and the head stops at the end of the flood and won't move. Take a few minutes to figure that one out.
-
I guess you better tell your man to flock off then.
-
Well what the Flock you know its all fix and I,m going home
