Subject: [rollei_list] T shutter jam
After shooting a dozen or so rolls through
my newly-acquired T, the shutter jammed.
The camera was cocked but the shutter
button was frozen. I opened the back to
remove the film but when I shut it again
the shutter is still frozen. (Yes, the shutter
release guard is open.)
I am assuming that this is a job for a proper
repair guy. Any thoughts as to cause?
I know little about the Ts and thought it
prudent to sound the pros before sending
it out. Many thanks in advance for your
advice and thoughts.

Please edit when responding to the digest.
I am not as familiar with the T as with earlier models
but I think the mechanism is similar. Jamming can come from
the shutter not being fully cocked. Its cocked by an
articulated lever which is worked by the crank, the system
works against a cam which is moved by the focus knob to
adjust the throw to compensate for the shutter position
changing with the distance focused on. If there is a bit of
wear the lever will not move enough to fully cock the
shutter. This may happen only at one end of the focus travel
but will eventually happen all over. When the shutter is
only partially cocked it will latch but not fire. I think
that may be what is happening here. There is an internal
adjustment for the lever stroke. That adjustment may be
enough or, if there is enough wear, the eccentric adjustment
or cam may need to be worked on. This is definitely a job
for a pro.
