  • Page 16 SH-MF1 Training Safe Shutdown In this machine, a power relay drive circuit protects the HDD unit. After the main power switch of the machine has been turned off, the relay drive circuit keeps the power supply to the controller until the HDD unit has been shutdown safely. When shutting down from normal stand-by mode, and the safe shutdown takes more than 2 minutes, there is a problem with the controller board.
  • Page 17 SH-MF1 Training Safe Shutdown Circuit This diagram shows the safe shutdown circuit. (More details in notes below.) Slide 17 After the AC switch is turned on, the relay turns on at about the same time that the software starts up. When the AC switch is turned off, the controller detects the change in the state of the ACSWON_N signal.

  • Page 32 SH-MF1 Training Security & Encryption Unit Action Objectives To let customers use Ricoh MFPs/Printers without security concerns caused by information leakage from the hard drives of their products. Through these actions, we hope to increase customer retention and product competitiveness, and avoid unnecessary legal challenges from customers.
  • Page 33 SH-MF1 Training Security & Encryption Unit Installation The machine contains the Security SD Card (Security and Encryption Unit) in Slot 1 (upper), when shipped. It is already installed. The technician does not need to do anything. If the user wants to use HDD encryption, they must enable it with user tools.
  • Page 34 SH-MF1 Training Security & Encryption Unit Installation If you are installing a new machine, it is recommended to activate the Security Unit by selecting "Format All Data". Note: This method is recommended because there is no user data on the hard drive yet (Address Book data, image data, etc.). If the customer wishes to activate the Security Unit on a machine that is already running, it is recommended to activate the unit by selecting "All Data".

Make an "nvram_key.txt"file in the "restore_key“ folder in the SD card. 4. Ask an administrator to input the encryption key (this has been printed out earlier by the user into the "nvram_key.txt"file.
  • Page 41 SH-MF1 Training Security & Encryption Unit Troubleshooting If the SD card and NVRAM are replaced, the HDD encryption unit and the Data Overwrite Security unit must both be re-installed after you complete the actions in the tables on the earlier slides (37, 38).
  • Page 42 SH-MF1 Training Security & Encryption Unit Important Immediately after encryption is enabled, the encryption setting process will take several minutes to complete before you can begin using the machine. If encryption is enabled after data has been stored on the disk, or of the encryption key is changed, this process can take up to three and a half hours.
  • Page 43 SH-MF1 Training Security & Encryption Unit Important The machine cannot be operated while data is being encrypted. Once the encryption process begins, it cannot be stopped. Make sure that the machine's main power is not turned off while the encryption process is in progress. If the machine's main power is turned off while the encryption process is in progress, the hard disk will be damaged and all data on it will be unusable.

The first scanner contains the exposure lamp, reflectors, the 1st mirror, and the lamp regulator. The second scanner contains the 2nd and 3rd mirrors. The regulator is mounted on the scanner to reduce the wiring between the lamp and the regulator.
  • Page 92 SH-MF1 Training Original Size Detection There are no width or length sensors in the scanner. If the original size is different from the paper in the selected paper tray, the customer must input the correct original size at the operation panel. By default the original size is assumed to be the same as the selected paper tray.
  • Page 93 SH-MF1 Training Copy Display is Changed Because there is no original length or width detection, the SH-MF1 cannot detect the original size. This means that SH-MF1 does not have the Auto Paper Select function. Because of the above, the user must input the original size at the start of every job.
