Important:
• Only the USB media 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 media with a flash memory (to be connected directly to the USB port)
and its capacity is between 256 MB and 512 MB (or 1 GB).
- Operation of the USB media used for updating has been confirmed at the input check of
this equipment (Test mode 03).
( P.2-4 "2.1 Input check (Test mode 03)")
- USB media which comply with the following standards regulated by USB-IF (USB Imple-
menters Forum)
Class number:
Sub-class number:
Protocol number:
* Most common USB media 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 media complying with USB1.1 and 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 guaran-
teed.
• 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
media. 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.
