Question about Ricoh Aficio 450 Copier
The Key Operator code allows access to the configuration of the machine and is
equivalent to the console root password of a server. Users can be tracked and their
access limited by assigning user codes with ID information. The assigning of user codes
is performed via the Key Operator code. The default Key Operator code is “0000” and
distinct User codes are not by default enabled. However, even if the Key Operator code
is set to a non default this can be overridden as detailed in the service manual by
entering service program mode, pressing the interrupt key then 107 on the keypad and
finally, holding down the <c> key for 3 seconds (Ricoh 1,pp.4-5). No authentication is
required. Once in this mode, all system parameters including the Key Operator code
can be reset to factory defaults. This not only allows the machine to be made inoperable
but also allows data to be archived to the hard disk or memory, allowing data retrieval at
a later date. An alternative way to achieve the same result would be to open the
machine, reset the systems NVRAM, automatically resetting the machine to factory

This code can be reset by turning the machine off at the red power switch located on the left side of the machine. If this does not fix you problem, then the machine may need to be serviced.
Let us know if you have somethin more to ask else accept the suggestion.
