These key functions are enabled when an optional hard disk is installed:Job Building,
Printer lockout, storage used by Application Solutions such as FormsMerge Job Buffering
(print spooling), email spooling, font and macro storage, User-based billing, Job
Park (through a power-off and power-on cycle), hard disk-related administration (Disk
wiping, Disk encryption, Disk diagnostics).
The 'Disk Encryption' function provides a randomly generated encryption key used to
encrypt all data stored on the hard disk. This key generated by each printer is unique
to that specific printer.
With 'Printing Lockout', a disk may also be locked with a user PIN. This prevents
any submitted jobs from printing. All held jobs are stored on the hard disk until
it is unlocked. 'Disk Encryption' should be used with this setting.
