Note that my CPP2 had been idle for several months but since none of my local labs process film (I'm not talking 35 mm) anymore I was attempting putting it back into service. After letting my exposed film (120/220 and 4x5 sheet) amass I recently started processing my film in my CPP2--I started with the C-41 first. Problems encountered----the drum rotates as it should in the clockwise position but tends to stall on the reverse---the 1500 series tank is not overloading it---it has worked fine in the past for my expert drums too. Any suggestions---should ZI assume the motor itself or ??? Note that sometimes it will reverse as it should but at other times not---it tries but needs help----like it's straining and just can't get it done---I'm looking for an affordable fix--not paying several hundred dollars for a $20 repair. Advice ? Experience? Let's have it!
