Window Perf lifting while printing-Need help

[Red Alpha]

Hello,
I have a mutoh 1641sr printer and am attempting to print on a new material. Its the black label window perf from fellers. I noticed that the material is lifting up from the liner while its printing an I had to stop it because of a head strike. I already raised up the print head to mid level. I read on another thread that lowering the heater temperature might work. I have never messed with the heater.

I'd try lowering the temp to start, as it does sound like there is too much heat.

Turn the heat down, turn the vacuum up all the way, and clean the platen with alcohol to make sure the material isn't sticking to the platen. If none of that helps, you might need new pinch rollers.

This printer has 3 settings Normal, Dryer and Fixer . I tried the dryer setting

I'm going through the menu options and I don't see the options to change any of those settings

I'm not familiar with Mutoh, as I have Roland's, which allow you to adjust the temperatures of both the print and dryer heaters.

It's the pre and platen heater you want to lower. The dryer usually doesn't cause the buckling.

Check the settings in your RIP. Usually the vacuum and heat settings can be controlled there. Otherwise, they should be in the Setup menu on the printer.

I'll check the rip here in a second. I actually got a good print by raising the print head to high from mid. Material is still buckling but the head is not striking

I think I use the same window perf and have the same issues on my HP 360. I usually have to turn the temp down as far as I can, adjust the vacuum, and put clamps on the front of my material.

I wasn't sure how much to lower it so I went from 42 C to 35 and so far its good. I still have the print head on high but since it hasn't buckled at all I'm going to try it on mid. My only concern is that 35 too low and will create other issues.

Yeah. So far lowering to 35 c from 42(default) and turning on the vaccuum to high seems to be working
