Correcting USB Problems
If you are having difficulty using your printer with a USB
connection, read the information in this section.
Make sure that your computer is a Windows XP, Me, 98, or 2000
pre-installed model
Your computer must be a Windows XP, Me, 98, or 2000
pre-installed model. You may not be able to install or run the USB
printer driver on a computer which is not equipped with a USB
port or which has been upgraded from Windows 95 to Windows
XP, Me, 98, or 2000.
For details about your computer, contact your dealer.
Make sure that EPSON USB Printer Devices appears on the
Device Manager menu (for Windows Me and 98 only)
If you canceled the plug-and-play driver installation before the
procedure was complete, either the USB printer device driver or
the printer driver may be incorrectly installed.
Follow these steps to check the installation and reinstall the
drivers:
1. Turn the printer on, and plug the USB cable into the printer
and the computer.
2. Right-click the My Computer icon on your desktop, then
click Properties.
3. Click the Device Manager tab.
