Downloads the Latest Package
The machine accesses the server to check for the latest package version.
If the version of the package on the global server is later than that of the package installed on the machine, or if the machine has not downloaded the firmware package, the machine downloads the latest package in the background even when the customer is using the machine.
If the download fails, the machine will retry downloading 76 hours later.
The downloaded package can also be used with SFU (Smart Firmware Update). A package downloaded with SFU (Smart Firmware Update) can be used with ARFU (Auto Remote Firmware Update) and vice versa.
When replacing the hard disk, information concerning the current firmware package becomes lost from the hard disk. So, even if the latest firmware is on the new hard disk, be sure to download the latest package data.
When the machine connects to the server where the package files are stored, the DNS settings and the name solution by DNS is needed. The machine will still try to download the package even if the name cannot be resolved, but will fail as the name is not resolved.
The time and date to send the next inquiry to the global server can be checked with SP5-886-116 (Farm Update Setting: Auto Update Next Date).
The auto remote firmware update is executed every 76 hours.
ARFU Update Determination
When the machine has successfully downloaded the latest package firmware file, or if the file has already been downloaded, the machine verifies whether a firmware update is necessary.
If the timing of determination is within the update prohibition period or day set in the SP configuration or Web Image Monitor, the machine will retry the firmware update determination 76 hours later.
If the machine is in use at the time of firmware update, the machine will retry the update. The machine retries update up to three times at one-hour intervals (which can be changed in the SP configuration). If the machine is in use on all three retries, the machine will retry the update 76 hours later.
Situations in which the machine is determined to be in use
No. | Situations in which the machine is determined to be in use |
|---|---|
1 | When the operation panel is used within 30 seconds |
2 | During firmware update |
3 | While firmware update is disabled |
4 | While printing (copy, printer, fax, re-printing via network) |
5 | While scanning (copy, scanner, fax) |
6 | Retrieving image data via the network |
7 | While initial setting ([Settings] icon) or SP is being set |
8 | While fax is transferring data |
9 | During on-hook/on the handset |
10 | During the PC-FAX process (from PC to machine data transfer to the end of the job) |
11 | While switching to/from the energy saving mode |
12 | When not being able to run the firmware update due to the modules that are running e.g.) Waiting for DCS transfer (refer to appendix), accessing devices such as HDD/SD card, etc. |
13 | While displaying a preview |
14 | While the document server function is in use |
15 | Connecting to TWAIN |
16 | During the interrupt copy process |
17 | While displaying the printer menu |
18 | While updating the display for the document server function via WIM or for stored fax documents |
19 | While writing log information |
20 | While accessing the address book |
21 | During SC |
| 22 | While shutting down |
| 23 | While importing/exporting SP settings |
| 24 | The interval between changing settings that require a reboot and actually rebooting (A reboot notification message pops up after changing the settings.) |
| 25 | While verifying the operation panel (smart panel) |
Update Process
When the machine updates the firmware by Auto Remote Firmware Update (ARFU), a message dialog box opens to indicate the start of update.
“Cancel” and “OK” buttons appear in the dialog box. The update can be manually started by pressing “OK” or starts automatically if the button is not pressed for 30 seconds.
If “Cancel” is pressed, the machine will perform the same retry process as when the machine is in use at the time of update.
If the firmware update and three retries fail, the SC of the defective module during the update will be displayed as the update error. If the following SC occurs, replacing the corresponding device restores the machine. The SC will not be reported to the call center.
Device and corresponding SC number
Device name | SC number |
|---|---|
Engine board | SC845-01 |
Controller board (PCB15) | SC845-02 |
Operation panel (normal panel)*1 | SC845-03 |
Operation panel (smart panel) | SC845-04 |
FCU | SC845-05 |
*1 Not available for this machine
Cancellation of update by user
Using the operation panel, the user can cancel the update (including update through the retry process) being performed by Auto Remote Firmware Update (ARFU).
However, while the firmware of the operation panel is being updated, cancellation is not possible because the keys are disabled.
(Since the update of the operation panel firmware is performed at the end, you cannot cancel the update at this point.)
If the update is canceled, the machine will reboot when the firmware update of all modules included in the following parts is complete.
- Engine Board
- FCU
- Controller Board (PCB15)
- Operation Panel
For example, if the first firmware update for the Controller Board (PCB15) is canceled, the machine will reboot when the firmware update of all modules included in the Controller Board (PCB15) is complete.
The firmware configuration contained in the package is listed in the accompanying SERES release note.
If the update is canceled, it will be performed again 76 hours later. If there is a difference in version between the package obtained at that time and the one already stored (in other words, the one canceled), the old package will be discarded and the latest one will be received.
