If you are having difficulty using your printer with a USB connection, see if your problem is listed below, then follow the instructions given to resolve the problem.

Printer does not work correctly with the USB cable

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

Use the USB cable (C83623) recommended in System Requirements.

For best results, you should connect the printer directly to the computer's USB port. If you must use multiple USB hubs, we recommend that you connect the printer to the first-tier hub.

Operating system

Your computer must be a Windows Me, 98, XP or Windows 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 98, XP or 2000. For Windows Me users, your computer must be a Windows Me pre-installed model or upgraded from a Windows 98 pre-installed model.

For details about your computer, contact your dealer.

Printer software installation

Please note the following.

When using Windows 2000, you must follow the steps in the Setup Guide to install the printer software, or Microsoft's Universal driver may be installed instead. To check if the Universal driver has been installed, open the Printers folder and right-click the icon for your printer. To open the printer driver, click Printing Preferences on the shortcut menu that appears, then right-click anywhere in the driver. If About is displayed in the shortcut menu that appears, click it. If a message box with the words "Unidrv Printer Driver" appears, you must reinstall the printer software as described in the Setup Guide. If About is not displayed, the printer software has been installed correctly.

If the Digital Signature Not Found dialog box appears during the installation process, click Yes. If you click No, you will have to follow the steps in the Setup Guide to install the printer software again.

If you canceled the plug-and-play driver installation before the procedure was complete, the USB printer device driver or the printer software may be incorrectly installed.

Turn the printer on. Plug the USB cable into the printer and the computer.

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

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 Stylus Photo 935 appears, the printer software is not installed correctly.

If neither USB Printer nor EPSON Stylus Photo 935 appears 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 Stylus Photo 935 and click Remove. Then, click OK.
