Verscamm media tracking off to left

[landdesigns]

I have been noticing the media on my Verscamm (Vp 300) has been tracking to the left while doing prints.

I replaced the wheels a few months ago and have been checking the way the media is loaded and everything looks fine? Confused?

our old vp-300 did the same thing, I think a lot of it has to do with the fact there are only 2 pinch rollers. I got much better results when I used the white media flanges to load the rolls.

Have you checked to see if the printer is level? are the 2 bars that hold the media level?

If the problem showed up after wheel replacement, are pinch wheels installed correctly? The taper needs to run to the outside.

this happens time to time on to me. if the wheels are installed correctly, make sure the vinyl roll is nice and tightly wound and flat on the edges, if not it will track to the right or left... just what i found my problem to be. after you tighten up the roll, load up the roll and pull it through evenly and do a page cut to get a fresh straight edge to work with.

This can happen on any printer.

We have a VS-640 and a production printer and it happens on both if you fail to do one critical thing - center the media.

Doing so however is very easy. You simply grab the media in the middle with one hand and pull it straight down, you can usually feel that it either went left or right a bit. We noticed this on our media take up system when the media down there would always roll into one direction and wouldn't end up in an even roll.

Hope this helps.

Yeah what he said.

The other thing I would add is to never trust the sheet cut end if you haven't been centering the media. Media will drift no matter what and you end up "accumulating" that error. Sheet cut makes a straight line, but is it 90 degrees to the side? Wife was running a massive decal job and the contour cut ate a 100 or so units. She said: "But I was using the sheet cut" I removed the roll and squared it by hand. It was 9/16" out of square in 54" !!!

Yea man, it's interesting...if someone told me to write a zero to hero wide format print book I'd probably have it done in 2 weeks and then would make edits for the next 10 years

It's never the big stuff, it's always these small things that make your work hard.


EDIT:

See

Another very important thing I forgot to mention. NEVER leave your pinch rollers on only half the media. What I mean is starting print when you have one half of the pinch roller on the media and the other not on the media. What will eventually happen if it's a long print run is, that pinch roller will push the media, from the direction where it's not on the media towards the end that is on the media so that can happen there is if you're printing you could find the vinyl lifted itself from the adhesive and the print head can hit it and then you've got yourself one heck of a mess. IF you're cutting it could lead to inaccuracies in the cut and then you may have to throw away a whole bunch of media.
