EPSON Stylus COLOR 860/1160 Revision C
Adjustment Adjustment 137
5.2.3.8 USB ID input
When you replace the main board with a new one, you have to input the
USB ID newly into the specific address of the EEPROM.
When the Printer and the PC are connected with a USB cable, the USB
port driver loads the unique code from the specific address of the
printer’s EEPROM and the provides the USB port number to the unique
code. The USB port driver controls the several USB ports under the
Windows 98 environment.
A unique code called USB ID is input to the specific address of the
EEPROM in our manufactory and the following total 18-digit code is
used as a USB ID for the EPSON ink jet printer.
n Factory line number (3-digit)
n PC number (2-digit)
n Input year/month/date/time (hour,minutes,sencond) (12-digit)
The timer data of the PC is used for this input data.
n Number 0
An “0” is automatically added for the last digit in the input
program.
In repair activity, we use a 10-digit code of the Serial number for a USB
ID. The remaining 8digits code is generated in the adjustment program
and added to the serial number automatically.

CAUTION
In case the USB ID is not input in the adjustment
program after the main board is replaced to new one,
the USB ID may not possibly unique one.
In this case, the USB ID conflicts the another peripheral
USB ID in the USB port driver and the another USB
peripheral may not possibly be used with the USB.
