Loading film in the PhotoBlaster may require some futzing. From my experience, sometimes the "teeth" on the take-up reel don't want to grab the edge of the film. Be prepared to adjust your film, you may lose some photos at the start of your roll.
I get emails once in a while with repair issues. I don't know how to fix 'em; if you do, or know somebody that does, please let me know, and I'll post it here.
You can contact me if you have any fixes you'd like to share or discuss.
