Error E000532-8001 on iRC3170

Question

My iRC3170 shows limited functions enabled on the screen. I go into Common Settings and turn off limited functions, power off/on the machine and it displays error E000532-8001 and offers to turn on limited functions again.
The stapler does not work and the paper output is partially reatined in the output slot - not fully discharged onto the output tray.

What can I do?
