MX-M350/M450 N/U  ROM VERSION-UP  12 - 2

3) Enter the file/folder number of firmware that tries to be

updated with 10-key, and press [START] key.

If selecting the file, "FIRMWARE UPDATE.. ARE YOU SURE
?" is displayed. ([1]: execute, [2]: get back)

4) If the operation is normally completed, "COMPLETE" is dis-

played. When the error occurs, "ERROR" is displayed.

NOTE:

If the Imager locks up or loses power during the upgrade, it
corrupt the firmware. If this occurs, you can rescue the firm-
ware using the "C. Version-up procedure 3".

To make version-up of the ROM, position of the DIP switch should

be below.

When shipping, the setting of controller write protect bit is cancel
mode side.

When entering the diag mode to write into ROM, some keys on the
operation panel and the LED panel are used. Necessary informa-
tion including menu items and messages is displayed on the LCD
panel.

[START] key is used as [OK] key, [DOCUMENT FILING] key and
[FAX/IMAGE SEND] key as up/down select keys, [JOB STATUS]
key as [MENU] key, and [CLEAR] key as [BACK] key.

1) When performing version-up of the firmware by using the file

transfer tool (File1PRN), the printer driver of the target model
must be installed in advance.

2) When performing version-up of the firmware by using the USB

I/F, take note of the following items.

Since the port for the file transfer tool (File2PRN) differs from
the port for the print mode, if the port for the print mode has
been already made, be careful not to mistake them. If the USB
port for the print mode has been made, it is advisable to delete
it in order to avoid confusion.

(Making procedures of the port for the file transfer tool (File2PRN)

in the USB I/F mode)

When performing version-up of the firmware by using the USB I/F,
perform the following procedures to make the port in advance.

1) Install the printer driver of the target model.

In this case, set the port to other than the USB mode.

2) Set the DIP switch to the Flash ROM version-up mode, and

turn on the power.

3) Connect the PC and the main unit with a USB cable.

4) The PC detects the new hardware by Plug & Play function.

When writing the program files collectively without disassembling
the ROM's from the PWB's, and when writing the program files into
an optional ROM:

NOTE:

The PCU ROM, the FAX ROM, and the scanner control

PWB ROM must be provided with the program to
operate.

An empty ROM cannot be used.

1) Connect the PC and the MFP control PWB with a I/F cable.

2) Turn on the PC and the machine.

3) Copy the file transfer tool and ROM program file into the same

folder of the PC. (When writing with the file transfer tool
File2PRN.exe)
Copy the collective ROM programming file and the file transfer
tool File2PRN.exe into the folder you desire on the PC.

4) The following display is shown after a while from starting the

machine.
