To the good people who are familiar with Pentax film SLRs, I need your help. I've recently bought a spotmatic 2 from the bay and tried to load it with film. However, after loading, I realised that I could not advance or rewind the film with the back closed, but could do both when the back is open. After taking out the film, I realised that there was slight resistance when closing the back, and that the film pressure plate was pressing against the metal rails. I think it's the pressure from the pressure plate that prevents the film from moving. Has this happened to anyone here? Is there a way to solve this? Thanks in advance!!!
