HP Latex 365 printing bad

[Annette Asberg]

Hi
I just wonder if anyone knows what wrong with our printer?
We are printing hundred if signs and all of a a sudden the printer starts to mess everthing up, please see attached picture.
Does anyone know why and what to do to make it happy again?

The material is buckling up on the heater and catching the upper part of the dryer unit when exiting, the ink is not dry so it smudges. We usually see this on some materials if you don't feed it out enough before printing starts, temp settings are too high, the platen has some goo on it so the backing sticks to the platen. You can try to lower the curing temp by 4-5 degrees, increase vaacuum a tad and/or use takeup. This has helped for us in many cases but it usually only happens on certain materials that we don't print a lot on. Good luck!

Exactly... material is touching the heater. You might also try using the take up reel. This will keep the material tight.

We use the same printer. Yes use the take up reel it makes a world of difference.
