Ricoh Mo-C1, Service Manual, Page: 570 / 1052

• This SP creates a 4 MB file to store a log on an SD card. However, this is not a completely empty
file.
• The created file will hold the number “2225” as the SCS key number and other non-volatile
information.
• Even if this SP is not executed, a file is created on the SD card when the first log is stored on the SD
card, but this operation takes time. This creates the possibility that the machine may be switched off
and on before the log can be created completely.
• If you execute this SP to create the log file beforehand, this will greatly reduce the amount of time
required to acquire the log information and save onto the SD card.
• With the file already created on the SD card for the log file, the data only needs to be recorded; a
new log file does not require creation.
• To create a new log file, execute SP5857-012 to delete the debug log data from the SD card and
then execute this SP (SP5857-017).
Firmware Update
Overview
The MCU (Main Control Unit) board flash-memory contains the software for this machine. To upgrade
the software, .SD cards are necessary. The SD cards contain the SCU and ECU firmware.
• Always turn the main power switch off before you insert or remove an SD card.
• Keep the main switch on during software installation.
• Store and handle SD cards carefully to protect them from heat, humidity, and sunlight.
• Before you handle SD cards, touch a grounded surface to discharge static electricity from your
hands.
