I just unloaded a roll of 120 film and all of the sudden the magazine is not locking onto the body.
It appears that the two holes are not left completely open for the body to enter into them.
Is there any way of fixing it?
PS: I haven't loaded any film, but I don't think it would matter?
If the camera was not properly cocked before the magazine was removed, you need to set the camera and magazine so that the indicator circles on the side of the camera and magazine are both white or both red.
The magazine slide must also be fully inserted into the side of the magazine.
These and other instructions can be found in the Hasselblad 500C/M Manual.
Yes, the fix is pretty easy but you'll need to undo the nine screws securing the front of the magazine. Remove the black aperture plate and you'll see a flat piece of metal the is actually a spring at the top of the magazine. When it is not seated properly, the dark slide can't push the right side of this "spring" - this prevents the top locking button from moving completely. This piece is what prevents the magazine from being removed from the camera if the dark slide is left off the film magazine.
A secondary issue is the spring loaded metal piece at the bottom of the magazine (easily seen with the film aperture plate removed). When the dark slide is inserted in the magazine, the tiny opening to the lower-left is partially covered and the camera shutter cannot not be released. With the dark slide removed, that opening is fully exposed. When the shutter release is depressed, a small metal "bar" extends from the camera body into this opening before the shutter can be released, this bar has to enter the film magazine. Older non-"A" backs has this piece on the left edge of the film magazine. This prevents the camera from taking pictures when the dark slide is in the film magazine.
