3) Turn on the PC and the machine.

4) Copy the file transfer tool and ROM program file into the PC.

(When writing with the file transfer tool fcopy.exe via parallel I/F)

Copy the collective ROM programming file and fcopy.exe 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.

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

machine.

6) Press MENU key several time to select an I/F to use from USB,

version is properly upgraded.

When writing the program into each ROM of the PCU PWB, the FAX
PWB, and the scanner control PWB individually by using an empty slot
for ROM copy on the MFP control PWB ROM:

Note: The program write target ROM installed to the empty slot for

ROM copy on the MFP control PWB ROM may be empty. (No
need to have the program data in it. The empty ROM can be
used.)

1) Set the DIP switch to the diag mode, and set the write protect
