I have an MX which has film transport problems. The
spacing between the frames is uneven, sometimes too
wide and sometimes non-existent. This can happen at
any place in the roll, but not on all frames - about 3
or 4 in a 36 roll. The repairman, who is a friend of
mine, said it was probably due to some worn sprocket
in the manual advance ratchet (using the winder, the
spacing was more even, but still not perfect). He
changed the sprocket, but the problem persisted (BTW,
he also checked up the shutter, which is smooth as
silk now). I compared the MX with a K 1000 that works
OK and the only difference I could find was that the
film transport sprocket (the one which has teeth that
engage the film holes) has a lot more fore-and-aft
play. The gears under the bottom plate look OK.
Perhaps the problem is not the film transport, but the
'safety' that keeps the shutter from being fired
before the film is fully advanced?
I'll try to remove the top plate (with my friend's
supervision) and see what I find there...He assured me
there are no springs or parts to fly away as the plate
is lifted :-)
I like this black camera very much and will try to
keep it running - maybe I'll learn some about camera
repair in the process.
