Note that this function may affect the equipment performance.
9.2.2

Precautions

When the data encryption function is set enabled, data currently stored in the HDD will not be retrieved.
Therefore when data encryption function needs to be enabled after the installation of the equipment, it
is necessary to back up the data in the HDD before setting this function and then recover them after the
setting.
• To ensure security, ask the user (machine administrator) to back up or restore the user's data
and information in the HDD. A service technician can back up or restore them only when the
user (machine administrator) permits it.
• Some data in the HDD cannot be backed up and can be left only on printouts.
When the data encryption function is enabled, the following items are restricted.
• 08-9112 (Auto Shut Off Mode timer setting (Sleep Mode)) is automatically set to "20: Not
used".
• 08-9113 (Screen setting for automatic energy saver/automatic power OFF) is automatically
set to "0: OFF".
• When the [ENERGY SAVER] button is pressed on the control panel, the equipment does not
enter the sleep mode.
• Since the energy saver mode cannot be set using the control panel, set it in TopAccess.
However, the setting of "Sleep/Auto Shut Off" cannot be changed in TopAccess and "Disable"
is displayed.
