[C] Patch update
Model specific folder name
Notes:
• Since the date and time set in the equipment are recorded in the firmware update log, make sure
that they are correct before updating the firmware.
• Never change the model specific folder name since it is used for identifying the data file when the
ones used for updating multiple models are stored in a USB device.
• Updating of the base version data must be completed in advance when an update of differential
items is performed.
• If the differential items update has failed, update the base version data and then perform the
differential items update again.
• Be sure to perform a standard update if such is required after the board or HDD has been
formatted. The update will fail if the differential items update is performed instead.
• The files for the standard package and the differential items package can be used to update
while they are stored into the same USB device. Moreover, it is also possible to store multiple
files for differential items package into the same USB device.
Important:
• Only the USB devices which meet the following conditions should be used for updating. Note that
updating with any devices 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. 3-8 "3.3 Input check (Test mode
03)")
- The USB devices which comply with the following standards regulated by USB-IF
(USB Implementers Forum)
Class number:
Sub-class number:
Protocol number:
* Almost all general USB devices comply with the above specifications 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.
