Help needed with Mamiya AFD 120 back pls...

Good day.

I've used this eslay purchased back before with no problems.

Now recently, when I load a 120 roll in and turn on the back is still showing "end" even after winding. The only way to "Fix" this is to open the loader door, light exposing some film space and rolling the wheel back and forth a bit, resetting back into the holder and letting it roll again. Sometimes this takes two times before the "end" disappears. All along the counter shows "1" correctly.

I've of course check the 120/220 pressure plate, I roll the correct amount to the arrow, sometimes a little before, a little after the arrow, all types.

Any suggestions please?
Thanks

Sounds like time for a cleaning.

glbeas, I bet your right. I'm going to start with the contacts on both the back and the camera.
Thank you for taking the time.

Be sure the wheel gets a good wiping with alchohol. If the problem persists take it to a repairman to clean deeper down and adjust anything out of whack.
