Hi Walker and others -
Walker, thanks for the suggestion above but unfortunately not working for me! I taped a barrier sheet to the star-wheel bar to guide film under front feed tray, but am still getting bad head strikes, now on both edges of sheet (see pics 1 and 2 below)
Sheets are clearly lifting at the sides. This is not a behaviour I have noticed before. I was wondering if they are getting affected by atmospheric conditions (like paper is sometimes)? Weather here is recently cold and rainy. But I try maintain a fairly consistent relative humidity and temp in my workshop, but maybe the weather is affecting the sheets?
Anyway, I have gone back to Manual Front feed. I am experimenting with carefully laying a 17" strip of slippery paper on top of the leading edge of the print as it emerges, the idea being to try and keep the sheet flat and the edges down. See pic 3 below. So far this has helped with the head strikes, but for some baffling reason I am now back to the micro-banding (which was why I was trying to use the Manual Rear feed in the first place).
To summarise…I am getting micro-banding when using the Manual Front feed and head strikes when using Manual Rear feed. Go figure
Wondering if using the Manual Front feed somehow bypasses the Custom Paper settings?
Any ideas or suggestion gratefully received, thanks
