X-E2: ‘! Switch off-Switch on’ message.

[Tenor]

My X-E2 has just started dicplaying the following message on start-up: ‘! Switch off, and switch on again’. This is followed momentarily by ‘cleaning sensor’ during switching off. Any ideas as to what this could mean?

thanks all

Tenor, what lens you had on the camera while having that message? If I remember well, I had it a couple times.
Always if I remember well, I had the 55-200 mounted. I've cleaned the contacts on the lens, maybe also on the camera. I think I haven't had the message anymore.

Update: only happens when 27mm installed, as it is most of the time. I will try to clean the contacts and see if that fixes the issue.

Happened with my XE1 and 35f 1.4. Cleaned contacts , solved the problem.
