Duplo DC 618 cutting issue

[slimbh]

Hi Guys,
I recently buy new Duplo 618 for help me cutting 24up business card.
I setting template on fiery impose then sending it to duple.
Infortunatly, the cutting is not straight.
The first cut is correct, but it shifts as the sheet advances and we end up with the last cut offset by 5mm.

When they sell me machine. they say the CCD scanner can also read the registration marks on every sheet to compensate for any shrinkage and image shift. But this don't work.

Any one know this issue?
Thanks

Try slowing the speed down, helps it be more accurate. And triple check your template, its possible that it's 5mm off and the Duplo is actually cutting correctly...or that your printer is printing skewed/shifted.
Finally, the CCD scanner doesn't read registration marks per se, it looks for a special square (included in most of the templates) and uses the position of that square to account for image shift. I never really utilize that feature though.
