Print Controller Design Guide for Information Security 2. Principal Machine Functions 2-1 Copier (MFP Models Only) 2-1-1 Overview of Copier Operations When a copy job is initiated, the scanning engine scans the original and forwards this data to the controller to be printed out from the printing engine. If "Store File" is selected at this time, the image data is also stored in the HDD. The Document Server function can also be used to scan images and store them directly to the HDD without printing them out, as well as to print out documents already stored in the HDD. In addition, a password can also be assigned when scanning a document for storage to the HDD, requiring the operator to input the correct password to print out the document. User Codes can be enabled to restrict access to the Copier function. 2-1-2 Data Security Considerations • Since the page location data is erased at the conclusion of every copy job, it is not possible to perform a job re-print on the same data. In addition, since the Copier function itself does not have any external I/F and does not perform any data exchanges or communication with external devices, it is not possible for any illegal external data to be introduced through the Copier function. 2-1-3 Protection of Copy Jobs in Progress When User Authentication is enabled, if one user attempts to cancel a copy job in progress that was initiated by a different user who had logged out before the end of the job, the MFP will prompt the operator for the username and password of the user who originally initiated the job. The only individuals who can successfully cancel the job are the Machine Administrator and the user who initiated the job. Also, the Machine Administrator always has the ability to perform operations on copy jobs in progress (e.g. job cancel). 2-1-4 Protection of Document Server Documents When User Authentication is enabled, it is possible to assign specific access privileges to individual documents when storing them to the HDD, which limits what operations can be performed on them (e.g. View, Edit, Delete, Full-Access). Users with View privileges can view, duplicate and print out documents but cannot delete or make any changes to the document (incl. filename). Users who have Full Access privileges can perform all operations on the document including viewing, printing, duplicating, editing and deleting, as well as making changes to the document's access privileges settings. Users who have not been assigned any Page 43 of 86
