5.2.7 Writing the USB-ID

The inherent USB-ID *1 for each printer is recorded in the NVRAM (EEPROM) on this
printer's C299MAIN board. Just as in the Stylus Pro 7500, where the serial No. is different
for every machine, so the USB-ID is different for each printer.
NOTE: USB-ID: NE101XXXXXXXXXXXX0 (The X represents the desired
character string, 0 ~ 9, A ~ Z) has a total of 18 digits. This ID is set so
that the USB ID will not overlap, even in cases where multiple Stylus Pro
7500's are connected to the same PC.
In after service, this must be implemented when replacing the C299MAIN board with a new
board.
Furthermore, making a copy of this ID or writing it is done with a PC on which an exclusive
"Stylus Pro 7500 After Service Adjustment Program" (OS: MS-DOS or Windows 95)
installed, and with the printer connected to the parallel (compatible) interface.
