Mamiya RZ67 beeping

SOURCE: Mamiya RZ 67 lens is stuck on body

This is likely because the shutter has not been cocked all the way. Return the lens to the fully locked position and advance the film with the lever all the way down to reset the shutter. If it still doesn't work, move the lever to M for multiple exposure, make sure the back is aligned and trip the shutter release. Then fully **** the shutter again by pressing the advance lever down fully and again until it is reset. Then try to remove the lens again.

A yellow led indicates the wind lever isn't cocked, or a weak spring hasn't returned it to the fully up position. A red led says pull out the dark slide.
