HP 64 cutter skewing on long cut jobs

Hello, has anyone had problems with tracking long cut jobs in a 64 cutter? Every time I try to cut anything with a long strip over 4" the cutter skews the material and all the cuts are off or it comes off the rollers and jams in the cutter. I tried to cut a wrap job that has a series of 10" x 7' strips for a van and as it cuts, the material will skew and all the cuts will be off. I have added tons of bleed, reduced the length of the cuts requiring me to tile it on the van, and reduced the speed to as low as 10ips. I am using IJ175 with gloss lam 8515. All my test cuts come out ok, but as soon a these long jobs go in, they come out messed up. I have had several tech support calls and 4 open cases for this skewing issue and miss alignment issues of small circles and ovals all of them with no resolution. HP seems to promise a call back or visit from a tech but they never call back. They just close my cases then I have to call a few days later for a new case. Has anyone had trouble with the 64 latex cutter?

Hi @randall7964, I can offer a few suggestions, although it might need at the end that you contact support again. here are my suggestions: if you are loading the media with a roll, try to load it as a standalone (it will depend on how big the material is) if you are using a roll, use the flanges and the guides try to do several copies of the same job instead of a long one check the status of the cutter, make sure the pinch rollers have the same strength and that there are no adhesive residues on them load the media using the front and back marks to align it, put the external pinches outside of the OPOS marks, and distribute the intermediate ones along the entire media. If none of these helps, I suggest contacting support again.
