AR-M550/M620/M700  ROM VERSION-UP METHOD  10 - 1
[10] ROM VERSION-UP METHOD
1. General
A. Version-up target ROM's
The version-up target ROM's are listed in the table below.
The version-up procedures of the firmware of this machine is per-
formed without disassembling the ROM from the machine. The new
program files are collectively written into the ROM's. Some new pro-
grams can be written into an optional ROM.
If, however, the above procedure is failed by an accident such as
power interruption during the version-up procedure, use the ROM copy
socket on the MFP control PWB ROM to make version-up of each
ROM individually.
[Kind of ROM]
All the Flash ROM's can be rewritten. (LAN, Centro)
[Block diagram]
B. ROM version-up is required in the following cases:
ROM version-up is required in the following cases:
1) When improvement of performances is required.
2) When installing a new spare part ROM for repair to the machine.
3) When installing a new spare part PWB unit for repair with the ROM installed.
4) When there is a trouble in the ROM program and it must be repaired.

2. Precautions
A. Relationship between each ROM and version-up
When performing ROM version-up, be sure to check the combination
with the version of ROM installed in the other PWB's including optional
ones.
Some combinations of ROM versions may not operate the machine
properly.
3. Necessary items for Flash ROM version-
up
A machine with ROM to be operated
A spare PCU PWB ROM, an MFP control PWB ROM (Boot, Pro-
gram), a scanner control PWB ROM (Each of which is provided with
the program to allow operations.) (Used when writing the program
files into the ROM is failed.)
A PC operating on MS-DOS, with either of a USB, Ethernet, or paral-
lel port.
USB cable, Ethernet cable, or parallel I/F cable (for connection of PC
and MFP control PWB)
FCOPY.EXE file (Parallel I/F, file transfer tool)
File2PRN.exe file (A file transfer tool for parallel, Ethernet, and USB
protocols)
Version-up program (compression) file
(The SFU file for writing a program to each ROM of the PCU PWB, the
MFP control PWB (boot, program), and the scanner control PWB, or
the SFU file for writing all the programs collectively.)
4. Flash ROM version-up method
A. MFP control PWB ROM DIP switch selection and 
Flash ROM slot
To make version-up of the ROM, the DIP set on the MFP control PWB
on the side of the machine must be properly selected.
When writing the program into each ROM (PCU, FAX, and scanner
control PWB ROM) of each PWB individually by using an empty slot
for ROM copy on the MFP control PWB ROM, the protect switch and
the diag mode switch of the MFP control PWB ROM are switched
over.
(MFP control PWB ROM slot)
The MFP control PWB ROM is provided with three Flash ROM slots:
CN4, CN5, and CN6.
The boot ROM is installed to CN4, and the main ROM is installed to
CN5. CN6 is an empty slot.
Us this empty slot of the MFP control PWB, CN6, to copy the ROM pro-
gram.
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:
The protect switch and the diag mode switch of the target PWB ROM
of writing program files are switched.
B. Operation panel
B. Operation panel
When entering the diag mode to write into ROM, some keys on the
operation panel and the LED panel are used. Necessary information
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.
(NOTE)
1) When performing version-up of the firmware by using the tile trans-
fer 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, per-
form 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. 
5) The driver of SHARP AR-M620N is automatically installed. (The
model name is indicated as SHARP AR-M620N, regardless of the
actual model name.)

AR-M550/M620/M700  ROM VERSION-UP METHOD  10 - 3
C. Version-up procedure 1
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) Set the DIP switch to the diag mode, and set the write protect DIP
switch of the target ROM to CANCEL side.
When writing the program data into all the ROM's collectively, set
all the protect switches to CANCEL side.
2) Connect the PC and the MFP control PWB with a I/F cable.
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,
Ethernet, and parallel protocols.
(Example)
7) Press OK key to display the following menu.
8) Transfer the program data from PC to the machine via either of
USB, Ethernet, or parallel protocol.
8A) When transferring with the file transfer tool fcopy.exe via parallel 
I/F
Boot MS-DOS from the PC. Use the FCOPY program to transfer
the ROM program data from the PC to the main unit.
(Procedure)
Type in Fcopy followed by a file name of the ROM program data,
then press Enter key.
Fcopy xxx.sfu Enter
8B) When transferring with the file transfer tool File2PRN.exe
Start File2PRN.exe on the PC. Use this program to transfer the
ROM program data from the PC to the main unit.
(Procedure)
Start File2PRN.exe.
Click Reference button and select a ROM program to transfer.
Select the target machine's port form Select Printer pull down list.
Click Send button.
The LED blinks and the LCD displays appropriate information as
operation proceeds.
Note: When version-up of each ROM of the scanner control PWB is
performed, the backlight of the display is turned off. This does
not mean a trouble. Wait for a while.
9) When "Result: OK" is displayed after a few minutes, press Up/
Down keys to check that there is no display of "Result: NG."
Note: When writing the program file data collectively to the machine
without the FAX unit installed, "Result : NG" is displayed only to
the FAX. This can be neglected.
10) Turn off the machine, and set the DIP switch to the original posi-
tion. (Normal start side)
11) Turn on the machine, and use SIM 22-5 to check that each ROM
version is properly upgraded.
D. Version-up procedure 2
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

4) Turn on the PC and the machine.
5) 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.
