1. Cases where flash memory rewriting is
required
In the following cases, the program in the printer control PWB flash
memory must be rewritten.
1) When a bug or other error is found
2) Data stored in the flash memory is destroyed or deleted.
3) When the flash memory is replaced.
2. Necessary tools
1) Computer (PC) <Operates on MS-DOS.>
2) Parallel cable
3) Program data file (xxx.BIN)
3. Procedure
1) Print the configuration list to check the firmware version.
Use the operation panel of the copier to perform the following
procedure.
ONLINE <off line> 
 MENU <Test Printing Menu> 
 ITEM <Con-
figuration Page> 
 ENTER <The test page prints>
2) Connect the PC and the copier with the parallel cable.
3) Turn on the power
4) Execute SIM 67-14.
“Erase Flash Data?” is displayed on the LCD.
5) Press the ENTER key on the copier’s operation panel.
“Now Erasing” is displayed on the LCD.
6) After deletion of data, “Please Send Data” is displayed on the LCD
and the machine enters the ready state for data input.
7) Download the program file.
(Note) Never turn off the power during download.
Set the PC to DOS mode 
 Check that the display shows
