Duratex Banner Material keeps bunching up in the middle.

[MMPLarge Format]

I have had this issue a countless number of times. It always leads to me wasting a significant amount of vinyl and I no matter what I do I can't find a fix for it. I have an HP Latex 360 and I am trying to print a 15'x5' banner on Duratex Banner material but every time the banner gets past ten feet of printing, the banner begins to bunch up in the center AS its coming out of the rollers. To be clear, it seems the material is being pushed towards the center of the rollers, causing the material to wrinkle between the rollers and where the print starts, thus resulting in significant head strikes and damaging of the print. I have ruled out that it is a bad roll because it happens on literally every roll, even different brands that are not Duratex (Grimco's brand).

Sounds like you might need to get your printer serviced. Try calling HP tech support.

But only after 10 ft?
It could be a firmware issue, but i would hate to see what it takes for hp to correct it

It may be just adjusting mechanically. Could be wear and tear of bearings or belts stretching out. Just throwing it out there. I own an epson, it happens rarely.

I had the same issue using Grimcos Duratex 13oz banner on my Epson s80 and did these 5 things that allowed me to print on this material. I lowered the heat settings (1) before & (2) inside the printer, (3) reduced media suction + (4)media tension, and (5) raised my print head height and that allowed me to print without causing the bunching up. Hope this works for you

Is it happening on a new roll? I've had issues with JetFlex bunching up on my Mutoh. After the first 15 or 20 feet it runs fine. I unroll media so there's a loop behind the printer.
Something changed with the material as it never did this and now the last two rolls had issues.
