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:

Turn the printer on, and plug the USB cable into the printer and the computer.

Right-click the My Computer icon on your desktop, then click Properties.

Click the Device Manager tab.

If your drivers are correctly installed, EPSON USB Printer Devices should appear on the Device Manager menu.

If EPSON USB Printer Devices does not appear on the Device Manager menu, click the plus (+) sign beside Other devices to view the installed devices.

If USB Printer appears under Other devices, the USB printer device driver is not installed correctly. If EPSON LQ-300+II appears, the printer driver is not installed correctly.

If USB Printer, or EPSON LQ-300+II does not appear under Other devices, click Refresh or unplug the USB cable from the printer, then plug it into the printer again.

Under Other devices, select USB Printer or EPSON LQ-300+II and click Remove. Then, click OK.

When the following dialog box appears, click OK. Then click OK again to close the System Properties dialog box.

Turn off the printer and restart your computer. Then, reinstall the drivers from the beginning, following the instructions in the Start Here.

Printer does not work correctly with the USB cable

If your printer does not work correctly with the USB cable, try one or more of these solutions:

Make sure that the cable you are using is a standard, shielded USB cable.

If you are using a USB hub, connect the printer to the first tier of the hub, or connect the printer directly to the computer's USB port.

For Windows Me or 98, try reinstalling the USB printer device driver and the printer software. First, uninstall EPSON Printer Software using the Add/Remove Programs utility in the Control Panel, then uninstall EPSON USB Printer Devices. Next, reinstall the software as illustrated in the Start Here. If EPSON USB Printer Devices is not registered in the Add/Remove Programs list, access the CD-ROM and double-click epusbun.exe in \<Language>\WINME or \<Language>\WIN98 folder. Then follow the on-screen instructions.
