New Machine, need some help

Hey Guys,

So i got a brand new hp print and cut system 315 model

i got some 1.25 inches decals with text wrapping around it, ive printed thses in my rolland all the time with no issue.

i just printed 6k of them but as im cutting them the alignment is a bit off, and not consistent either from one side of the page to the other (6ft) the alignment changed.

now im doing small batches , i got the alignment consistent within two rows but they are still not cut properly and off the cut lines, what do i need to do to fix this issue?
