Use a жёсткий диск (160GB or larger) to buffer print jobs, collate large jobs or to store forms, fonts or macros. These key functions are enabled when an optional жёсткий диск 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), жёсткий диск-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 жёсткий диск. 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 жёсткий диск until it is unlocked. 'Disk Encryption' should be used with this setting.
