Introduction
The AR-FR4 adds a security function to the Sharp Digital Copier / Multifunction Laser Printer.
When the security function is added to the Sharp Digital Copier / Multifunction Laser Printer, the
image data generated for each printer, copier, network scanner, and fax job is encrypted, and
when the job is finished, the encrypted data is erased from memory and the hard disk drive.
Note:
To ensure that the data security function of the machine provides maximum security,
observe the following:
Change the key operator code on a regular basis (at least once every 60 days).
●
During the procedure for changing the key operator code, the current key operator code and
●
new key operator code appear in the display. Be sure to complete the procedure promptly.
Do not select a number for the key operator code that can be easily guessed.
●
The key operator programs are very important for security management. The administrator of the
●
machine should inform users that they are not to access the key operator programs without permission.
If the administrator and users of the machine are to be out of the office, security measures
●
such as locking the machine should be taken to prevent unauthorized access.
When the security kit is installed
When the security kit is installed, the following icon appears on the touch panel.
When the security kit is installed, data remaining in the unit is automatically erased
after each copy, print, scan, and fax job.
When data clearing begins, the following message appears for 6 seconds*.
NOTES
When printing a normal print job in printer mode, the image data is automatically cleared from
●
memory and the hard disk drive after printing is completed. Please note, however, that when the
job retention function (page 2-9 of the Operation Manual (for printer operation and general
information)) is used for printing, the data is retained on the hard disk drive. (The retained data
can be erased from the Job status display of the touch panel (page 1-14 of the Operation
Manual (for printer operation and general information)).)
If the unit power is turned off while image data is being cleared from the hard disk drive or
●
before jobs are finished, the data may not be completely erased. If you do not wish to leave
partially cleared data when the power is turned off, it is recommended that you use the key
operator program, "CLEAR ALL MEMORY" (page 3 of this manual), to complete data clearing
before turning off the power.
