Leaf Aptus II -5 not capturing

[NNN636747121378710391]

Greetings!
I am using a Mamiya 645 DF+ with a Leaf Aptus II-5 back. The camera is about 5 years old and has only shot about 50 exposures. I have both the camera and back fully charged and when I make an exposure, the screen is totally black- as if the lens cap is on. Any advice on what this could be related to?

It sounds like it could be a failing shutter. If you have an LS (leaf shutter)-equipped lens on it, try overriding that via custom function CF-17 (for P, A, or T modes) or CF-18 (for M mode). Set either of these to 2 and it will override the LS and force the camera into FPS only. If you get an image, it's likely a failing LS. If it's still black, it could be the FPS.
In either event, I suggest getting in touch with us in support (via the link in my profile) with some sample raw files so we can see if there is anything else that may be going awry.

Thank you! I will be contacting support later today! I am not sure how to get the custom functions going (I am new to this format!) thanks for your help!
