I think, sometimes the K-r goes to nirvana
.
This will help:
1. Power off your K-r and unload the accumulator. Demount the lens.
2. Look in front of your K-r. On the left side there is a grey aperture lever. Move this aperture down and hold this position.
3. Insert the accumulator, close the cover and activate your camara. Take a shot if you like (without lens).
This will fix the problem in all circumstance I ever had with mirror flops.
