This process erases all contents in the hard disk. If necessary, back up important data from the printer before starting the encryption.
From the control panel, navigate to:
Settings > Security > Disk Encryption > Start encryption
For non-touch-screen printer models, press to navigate through the settings.
Follow the instructions on the display.
Delete residual confidential information left by scan, print, copy, and fax jobs.
Adding a hard disk increases the printer memory and reduces the risk of losing a print job entirely.
