Controller
Hard disk
This device contains numerous types of data including user data:
1) Data of the documents scanned in upon copying.
2) Data of spooled documents in PDL format from the network.
3) Data of the documents used in security print, sample print, and delayed-
start print.
4) Data of the scanned-in documents
5) Job logs.
6) Downloaded fonts and forms.
For the formatting of the hard disk, the file system included in VxWorks is used.
The format, however, is not accessible even when the hard disk is connected
to PC. When a job is completed, its reference in the directory table is deleted
but the image data remains on the disk until overwritten by a subsequent job.
Image Overwrite feature enables an overwrite of the used data with
meaningless data. Also, Data Encryption feature enables a data encryption of
the HDD data.
Page Memory
This is a volatile memory used to store image data temporarily.
SEEP ROM
This memory contains the system’s setting information.
