Data Clearance Settings
Enabling this function activates the following security 
functions on the machine.
• The image data generated in each job is encrypted.
• You can automatically clear the encrypted data in the 
memory or on the hard disk drive after completing 
each job.
• If you enter the password below incorrectly three 
consecutive times, the input operation becomes 
locked for five minutes.
- Administrator password/user password to use when 
the user authentication function is not set
- Password for confidential folders and files in 
document filing
- Password for printing encrypted PDF for direct 
printing*
* This data cannot be used if you enter the password 
incorrectly three consecutive times. 
- Password for FTP pull print
To enable these features, touch [OK] when a message 
for confirming whether or not to enable the features 
appears, and enter the same code as that shown on the 
"Security code input" screen. Touch the [Execute] key.
Then restart the device.
After restarting, you can select from one to seven times 
for the "Clearance Time Settings".
Release Lock on File/Folder 
Operation
This function is used to release document filing folders 
and files and encrypted PDF files, that are locked due to 
the entry of an incorrect password.
Touch the [Release Lock on File/Folder Operation] key 
and then the [Release] key to release all locked items. 
After this is done, the items can be manipulated. When 
no items are locked, the [Release Lock on File/Folder 
Operation] key is grayed out.
Initialize Private Data/Data in 
Machine
The system-set values can be restored to the factory 
default state and the data stored in the machine can be 
deleted. 
Use caution, as this function cannot be canceled once 
enabled.
A high clearance time setting will increase security, 
however, the time will take longer to clear. It is 
recommended that you set it to an appropriate setting 
according to your usage.
