EPSON Stylus CX3100/3200

5.2.6 USB ID Input

Stylus CX3100/3200 is equipped with the USB Interface as standard. As the USB Port
Driver controls the device through the USB ID on Windows98 or iMac, a proper USB
ID is assigned to this product. Since the USB ID is stored in EEPROM on the Main
Board, the USB ID needs to be input again when the Main Board has been replaced
with a new one. The USB ID is an 18-digit alphanumeric character string specific to
the machine, and recorded at the particular address on EEPROM. The USB ID is
determined at the factory as follows:
Manufacture process line No. (3 digits)
PC No. (2 digits)
Date (12 digits) -The built-in time data of the PC is used.
"0" (1 digit)
In repair, the 10-digit product serial number is used as the 10 digits of the new USB ID,
and the new USB ID is completed with an 8-digit character string which is produced by
Adjustment Program and automatically added to the serial number. Then input the new
USB ID in EEPROM on the new Main Board.
