Roland VS640I off track

[icex]

Printed a 40' banner today. Pulled a bunch out straight and left alot of slack and kept pulling slack so that it woulden't pull and wrinkle the material. The machine got to the last 15 or so feet of the banner and began pulling it to the right, 5ft later it pulled out from under the wheel and through a motor error. I went ahead and printed the last 10 foot and figure we'll just weld/hem it together and it will be ok.

Is there any reason it off tracked so much? I left 2" on each side of the roller (54' material) and had it straight on the take up wheel..

Pulled to the left, not the right.

What was the vacuum power set at? Were you using the Take Up System at all?

I don't think you can let the printer pull banner material off the roll. You need to have it hanging off the back.

Also you may need to use more pinch rollers if your Roland has that feature. Just the 2 on the ends might not be enough.

Yes, we used the take up system.

The vaccum power was on high.

We pulled slack off the banner material, the machine never pulled it from the roll itself.

We also used all pinch rollers to hold the material.
