Apologies for reviving an old-ish thread. I seem to have the same problem as OP, and honestly it's driving me up the wall.
In my case the problem is with Foma film, which is in my experience quite thin, more so than Ilford and much more so than Trix for instance. I've wasted a few rolls of Foma 100, 200, 400 - all of them just go through completely. A lot of wasted film. The camera is a beautiful, beautiful Rolleiflex 3.5F III with a pristine 6 element Planar, and in otherwise mint condition. I really want it to work.
A bit of context: the sensing mechanism worked erratically when I first purchased it. I did have a couple of rolls going through fine, and the resulting photos were fantastic. However, most rolls just went through undetected.
I decided it would be too much of a gamble to keep using this as is, so I sent it off for a full CLA. Well it's now back from its *second* CLA. That's right: the first CLA solved nothing: actually, it made things worse: the camera detected no rolls anymore. I sent it back under warranty, including this time a sacrificial roll of Foma 100 for calibration, and explaining it I'd like the mechanism to be tuned to work with slim film. The repair person is Will van Manen, who I'm told is a reputable Rollei technician in the Netherlands.
Result: same story. 3 wasted Foma rolls. However, I've just loaded a roll of FP4+, which has gone though fine. So I thought I'd ask here: do I have to keep using this Rollei as is? Do I have to send it back hoping we get there eventually? Should I just give up hoping to use thin film with this camera and keep it only for thicker film? Which are the thickest B&W films anyway? Honestly, I'm not sure this sensing mechanism is the best idea Rollei ever had. My Rolleicord Va and my Minolta Autocord are 100% functional with all films, and I never missed the sensing mechanism. To put it mildly I'm frustrated.
