If the user has forgotten the encryption key, the
NVRAM must be cleared in addition to this: See the

Slide 107
The service manual contains two procedures for restoring the encryption key.
The first one assumes that the original encryption key has not been lost.
The second one is for use when the user has forgotten the encryption key
and lost the printout that was made by the machine.
The operation manual does not refer to these procedures. Instead, the user is
instructed to 'update the encryption key', which actually means 'make a new
one'.
