FLASH UPGRADE - ENGINE 
 
SHARP ELECTRONICS (UK) LTD 
DOCUMENT SYSTEMS GROUP

VERSION 1C 
MARCH 2002
 
 
 
The AR250 – 507 range of copiers will require their PCU, ICU and Operational Panel flash 
memory cards upgrading as new Firmware becomes available. 
 
A Flash ROM Exchange Scheme has been set up with T P Maintenance so that dealers  
can obtain pre-programmed updated flash memory cards. As an alternative to the  
exchange scheme, the upgrade of flash cards can be performed manually. The following 
explains how to perform the manual upgrade of the flash cards. 
 
To perform an upgrade, the following items will be required:- 
 
• 
Flash Memory Download Program “Flash5.exe” 
• 
Flash Memory Upgrade Files. 
• 
A minimum of one spare ICU Flash Card 
• 
Laptop PC with applicable operating system (Win95/98/ME/2000). 
• 
SCSI PCMCIA card and cable(Adaptec Slim SCSI 1460B recommended) 
• 
To make the upgrade easier a Female/Female SCSI connector would also be 
beneficial.  
 
Depending how old the SCSI drivers are that are bundled with your SCSI card, updates may 
also be required to the “ASPI” drivers. 
 
The earlier Windows 95 operating systems encounter driver conflicts with some SCSI  
devices. Because of this, Windows 95 version “a” will require the Microsoft patch file 
“IOSUPD.exe” upgrade before it can be used with the Adaptec 1460 SCSI PCMCIA card. 
 
The full version of Windows 98 (not an upgraded copy) will require an update to the 
“WNASPI32.DLL” file in order to overcome the “Flash5.exe” file not opening. 
 
To install or upgrade ASPI drivers on Windows 98SE, ME & 2000, download ForceASPI 1.7 
from either SharpEye CD1 or from the following website :- 
 
http://www.cyrus.troy.btinternet.co.uk/download.htm
 
 
“IOSUPD.exe and “WNASPI32.DLL files can be obtained from the Sharp Technical Web Site. 
 
 
UPGRADE PROCEDURE 
 
1. 
Unplug the copiers power cord and remove the following covers: 
 
    Glass 
Holding 
Plate 
    Copy 
Board 
Glass 
 
 
 
 
Dark Box Cover 
 
If you have a female/female SCSI connector and the AR-PB2A has already been fitted to 
 the copier, this connector can now be directly connected between the AR-PB2A SCSI  
cable and your Laptop SCSI cable.

If the AR-PB2A SCSI cable has not yet been fitted in the copier or you do not have a 
female/female SCSI connector (available from Micro Warehouse  P/N DCA4475), the 
following panels must also be removed (not AR287/337/407/505/507).

2. 
Without a female/female SCSI connector, connect the PCMCIA SCSI adapter  
cable to the SCSI PCMCIA card in the laptop and the other end directly into the  
SCSI connector on the copier’s ICU board. 
 
3. 
Fit the spare ICU card (must be the same as the model that is being used) into 
the IC master socket. Power up the copier and perform simulation “26-44” to enable 
the SCSI socket that the Laptop is now connected to. 
 
4. 
Power down the machine and remove the OPE and PCU flash cards from the  
copier. Place a flash memory card in to the writing flash card socket of the ICU Pwb. 
 
5. 
Turn on the copier and then power up the laptop computer. Run the Flash 
Download program and ensure that the copier is being recognised as a SCSI device  
as shown below. (Any flash update files that are in the same directory as the 
“Flash5.exe” program will be displayed in the firmware box as shown below). 
 
6. 
Select the updated flash program for the relevant flash card that you have 
placed within the flash memory writing socket. In the download program, click the 
“Transfer” button to update the flash memory. The download will take approximately  
20 seconds. (It is recommended to flash ICU Cards with ICU firmware only, OPE Cards 
with OPE firmware etc). 
 
7. 
After the upgrade has been performed the copier will need to be powered off before  
the flash card can be removed from the writing socket. The same procedure can 
 then be performed for each of the other flash memory cards. 
 
  
Remember to close the “Flash5.exe” program between each flash card update. 
 
NOTE 
As the upgrade procedure uses a SCSI connection to the copier, the computer must always 
be powered on after the copier. This is so that the flash download program can recognise the 
SCSI device (AR copier). 
 
If the Laptop computer is running Windows 95 or 98, “Hot Swapping” is supported.  
As Windows NT does not support Hot Swapping, the Laptop will have to be powered down 
between each flash card upgrade. 
 
8. 
Perform Simulation 22-05 and check that the flash versions are being recognised correctly. 
 
 
AR-PB2A FLASH UPGRADE

The flash memory within the AR-PB2 Printer Board is broken down in to two sections.  
The first section replaces the Boot EPROM’s that can be found on other boards such as  
the AR5132’s BD14/15 printer board. The Boot flash memory is around 598kb in size and 
takes around 20 seconds to download to the AR-PB2 Printer Board. This data is  
responsible for booting up the Printer Board and displaying its menu options.  
 
The second section of flash memory is the Program/Font flash memory which holds the  
many in built fonts that are stored on the Printer Board. This file is approx. 16-18MB in  
size and so takes around 7-9 minutes to download. 
 
NOTE 
If you are upgrading from ARPB2(+) to ARPB2A firmware, you must ensure that  
the boot firmware is Downloaded before the Program/Font firmware and the upgrade must  
be done on an “Non” Cougar 2000 model (an F9 error code will occur if attempted on a 
Cougar 2000). 
 
If you are upgrading a PB2A with a later version of PB2A firmware, this can be executed on 
any Cougar model. 
 
Obtain the Updated Printer Board Flash Memory Firmware from either the Sharp Technical 
Web Site or from the “Sharp Eye” CD pack (Disc 1). This will be a “PB2_XXX.hex” file for the 
Program section of flash memory or a “BOOTxxx.hex” file for the BOOT section.  
 
Before upgrading the firmware, obtain a current printer configuration page. 
 
PROCEDURE 
 
1. 
Place the flash memory file in to a convenient directory on an IBM compatible  
personal computer. 
 
2. 
Unplug the copiers power cord. 
 
3. 
Remove the AR-PB2 Printer Board from the copier and relocate jumper JP1O9 to 
pins 2- 3.  This will write enable the printer board. 
 
4. 
Refit the AR-PB2 to the copier and connect a Parallel cable between the PC and  
the AR-PB2. 
 
5. 
Turn on the copier. In order, press the following front panel keys:- 
 
“P”, “Interrupt”, “C”, “Interrupt” 
 
The front panel of the copier should now show the message “Simulation No”

6. 
In order, press the following front panel keys:- 
 
“67” “Start” “14” “Start” 
 
Now wait until the copiers control panel changes from “----- “ to “Ready”  
 
7. 
On the computer with the parallel cable attached, open an MS-DOS prompt box.  
Now type the following command that will send the data to the copier and press  
the enter button :-  
 
Copy /b BOOTXXX.hex LPT1: 
 
Please Note: 
 
The BOOT flash data performs the communication with the copier at power tip and adds  
the Simulation “67” codes. Once the download of the BOOT data begins the power must  
not be removed from the copier until the download is complete. If this download is 
interrupted, no further downloading will be possible. 
 
The syntax above depends upon which flash memory you are downloading to the AR-PB2.  
The XXX represents the version number of the flash memory upgrade. The XXX should be  
replaced with the version number that you are trying to download i.e 111 or 221 etc. If you  
are not currently in the same directory as the flash file, the correct path should also be 
included  i.e. C: \Flash ~PB2_XXX. hex. 
 
The speed of the download will depend upon the speed of the computer being used. If a 
download  
is performed within a Windows 95 DOS window, the download time will be quicker than if  
you shut down the computer in to MS-Dos Mode. On a typical Pentium 120 running in 
Windows 95 DOS window, the download will take around 7 minutes. 
 
When a download is performed from a Windows 95 DOS window, the file is first spooled  
and then placed in the local print queue.  This means that the PC sending the flash  
memory could then be used for other tasks. Windows 95 will however have to be left  
running until the download has completed. 
 
Whilst the BOOT flash memory upgrade is in progress, the “BOOT” section of the copiers 
control panel will change from “Ready” to “Receive’’, ‘‘Sum”, “Erase”, “Blank”, “Write” and  
then “Verify”. If the upgrade is successful the message will finally read “OK” 
 
8. 
Power cycle the copier off and then on.
