Ink Smearing

More than likely, your heater settings are causing the banner media to buckle, causing a head strike with the media. That would account for the smearing that you are experiencing.
The solution(s) would include:
1) Lower your heater settings.
2) Use a tensioned take-up system which will force the media to remain flat on the printer platens.

Thank you for your help folks. My banner heat settings are normal… around 40°C and the heads are set to thick too but I Bob Price mentioned the take-up reel… I finally realized that the tension hasn't been tightened in a long time. Sheesh, thanks for the reminder. I think that should do the trick.

We are getting better prints now with lower heat setting, 40 deg caused vinyl to buckle, ever so slightly, causing banding and sometimes head strikes. Does not help to tighten the take-up, as the waves go across. The media expands with heat, and it has nowhere to go except up. Try 30 deg. C, see if it helps.

One thing I have done w/ my Mutoh is re-roll the banner material on the back. I've found it sometimes pulls at different rates across the width, so when I pre-roll it out to give it some slack, never strikes anymore - just sucks to have to babysit.
Still happening
Ok folks, I've tried adjusting the heat settings (Pre: 30°, Print: 35°) and the tension on the take-up reel and I'm still getting media strikes. The media is always set to thick too. This is such a strange problem because I've used the same settings for over a year then this suddenly starts happening.
I'm clueless now… anyone have anymore thoughts?
