Today, I gave my local lab a roll of Ferrania Solaris 200 to develop. When I came to collect it, the lab guy told me that the roll had jammed his minilab machine twice. When he had fed it into the machine, it had given a "sprocket hole error" and he had had to shut it down and respool the roll in his darkroom (which ruined half the roll, but that's not his fault). He had then tried it again and had managed to get it working, but then the ending of the film had jammed again. The results are completely unusable. Luckily the roll was only for test shots and I didn't even have to pay, but this whole thing left me wondering: has this happened to anyone else? Is there anything special about Ferrania sprocket holes or film containers? The lab guy told me he'd never seen this happen before, and I have no reasons not to believe him. What's wrong? The machine or the film? I'll bring in another roll of the same stuff tomorrow and see how it goes (I expect it to jam again, to be honest). Any similar experiences from anyone?
