Important:
• Only the USB devices which meet the following conditions should be used for updating. Be
careful since updating with any device other than the above is never guaranteed.
- A combination USB device with a flash memory (to be connected directly to the USB port)
and its capacity is 2GB or more.
- Operation of the USB device used for updating has been confirmed at the input check of
this equipment (Test mode 03). (& P. 3-7 "3.3 Input check (Test mode 03)")
- USB devices which comply with the following standards regulated by USB-IF (USB
Implementers Forum)
Class number:
Sub-class number: 6 (=06h) (SCSI transfer command set)
Protocol number:
* Most common USB devices comply with the specification above and can be used for
updating. However, the operation in all the Multi Functional Digital Color Systems and
Multi Functional Digital Systems is not necessarily guaranteed since the most of these
devices are developed based on use in a PC environment (Windows or Macintosh).
Therefore, check thoroughly that the device is operational in the equipment for which
the updating will be performed when purchasing it.
• The USB devices complying with USB2.0 can be used for updating.
• Do not update the firmware by any storage device other than a flash memory (such as a
USB connection type memory card reader, CD/DVD drive or hard disk), since it is never
guaranteed.
• It is possible to store the model specific update program and the data file for updating
directly in the root directory when you store the updating data file for one specific model in
the USB device.
However, if the model specific folder for the same model as that of the data file stored in the
root directory already exists, this will have priority.
