Help Please PVC touching the bottom of the head

[Peter Dee]

Has the media been in a damp environment?

we have had some wet weather recently. but not that im aware of.

i presume you are calling pvc = vinyl turn the heaters off if it still does it send it back, some backing papers dont like being heated as said if damp.

no PVC is banner material. Sorry i think you guys call it banner material or flex face

[Peter Shaw]

Make sure you’ve got enough hanging out the front of the machine. This helps the vinyl drop and move forward. Attach bulldog clip, weights etc to help.

thanks

what do you guys call banner material. Is it vinyl or what????? 😕 (?)

[DaneRead]

i am busy printing at the moment.

I thought it could be the heaters. so i put the rear heater on low but then heated it up on the print head and then kept the same on the front.

It started working then started creasing up then it wnet away.(thought it was fine)… then it came back. …. I then turned the heaters off completely seems to be going not too badly.

I have about 3 mt hanging on the ground now.

what heater settings do you all use on banner material.

[DaneRead]

its starting to happen again not yet touching the heads though.

My heaters are on zero.

As ive been typing its gone away again.

I think it is in the material. As its coming and then going. Could it be that the media has been rolled onto the spool wrong. I am unrolling the media manually at the back. so its hanging freely.

banner low 30 deg ish but dont allow the machine to pull a heavy new roll as that will not help.

I do banner material at Print-48 degrees / Dry – 50 degrees (Celcius). (As per machine suppliers recommendation).

Any less than that & I was having ‘issues’ with it wearing off instead of penetrating the material.

I have found that a couple of bull-dog clips on the leading edge for the first metre stops it sticking…as does wiping the heater faces with a silicone polish.

so what setting must i use ??? you guys are confusing me now

[Colin Crow]

Wrinkling can sometimes happen when the material is skewed in the feed. As it progresses tension builds on on side of the roll holder and causes a longitudinal crease. The answer is to load carefully and if the material is reverse wound then pre-feed some material off the roll down the back of the machine to stop the tension against the sides.

as we all resolve our problems with different makes we can only say what works for us, easy this digital printing aint it 😉

[DaneRead]

i am gong to put a bit of heat of the print head and the dry but the rear im going to keep cold.
