Sorry for the late answer but I think it'd help other Ricoh X/XR series owners.
Had the same issues, it's a "normal" sign of (un)use on old Ricoh KP/K cameras.
On the electronic shutters and semi-electronics models, there are 2 different ways to fix it.
-On the semi-electronics (such as the XR-7) you must remove the bottom plate of the camera and find a small pin, move gently this small pin "up/down" and shoot a few times the camera, it'd solve the issue in 90% of the cases.
When opened, put a very small amount of grease/machine oil (I recommend grease) on the gears, it helps on old camera (not WD40 or similar).
-On electronics models (such as the XR-M), no need to open the camera, remove the lens, unscrew the little metal plate on top of the internal mount, the small piece of metal with 2 screws that "protects" the mirror when up, and just bet it a little (0.2 mm is enough) and screw it back ... et voila.
On electronic models, if it doesn't fix the issue, the problem is more difficult to solve, it'd be :
-The glue that fixes the mirror that needs to be replaced, to do so, you must remove the mirror, heat the glued part, replace the glue and fix the mirror back, a nightmare to do as a lot of small part could go inside of the camera.
-The foam that was disintegrated and became sticky and must be replaced.
-An electronical issue, could just be a battery issue and replacing the batteries is enough (like on OM-2 cameras) or a broken wire ... difficult to find were is the problem
-The electromagnets that keeps the mirror up blocked or magnetized (normally it's the batteries that demagnetize it/them), if the mirror is not release with fresh batteries, it's probably that, the camera still works BUT you must remove the lens between each picture ... It'd be replaced but it'd cost probably more than the value of the camera.
Sorry but I didn't have picture as I did it a long time ago.
IT DOESN'T WORK WITH TLS series,
