Need help! Cutter error when cutting vinyl.

[Fooroogelm]

Help is needed!

We cut stickers printed on HP Latex 700 W onto HP Latex 54 Cutter.
The size of the stickers is 8.5x5 inches.
We cut from the HP Flexi Print and Cut program.
The problem is that the first row of stickers is cut correctly, but from the second row, there is a shift in the cutting line - which increases the further you go.

What could be the reason?

Thank you very much in advance.

Do you łaminate them before cutting.

There are vinyls, that deform so unevenly, that the cutter software can't correct it. Try another vinyl and see if it improves.
Since it is a Summa cutter in the end, it's the best cutter on the market.
You can also check, if you use the latest firmware and the latest availabe version of SAI software. There were some bugs at the beginning(before the L700 came out).

No.

How long is the job/batch? Are you printing w/ intermittent marks?

How long is the job/batch? Are you printing w/ intermittent marks?

About 6 ft long.
But the problems begin already from the second row of stickers.
Yes, we print w/ intermittent marks
