1. Right-click on My Computer icon, and left-click on Properties.
   
   
2. The System Properties window will open. Click on the Hardware tab, and then on Device Manager.
   • See article How to access Device Manager in Windows (All versions) if you require help.
   
   
3. Follow the section appropriate for the way that your Epson device connects to the computer:
   
   

   SCSI Scanners:

   
   
   
   
   

   1. In Device Manager, click on the [+] plus beside SCSI and RAID controllers.
      
      
   2. Check if the correct SCSI HBA (Host Bus Adapter) add-in card is listed and identified. The SCSI Controller should be listed with a manufacturer name e.g. 'Adaptec xxx SCSI Controller'.
      

      Figure 1: The SCSI card is identified as 'Adaptec AHA-2930CU PCI SCSI Controller':

      

      
      

      Note:
      An entry for a SCSI device does not mean that there is a SCSI interface port on the computer system to connect the scanner. There are different types of SCSI cards available such as storage controllers, RAID Controllers for SAS & SATA drives, and HBAs for SATA drives.

      
      
   3. If the correct SCSI card (SCSI Controller) is identified and is listed without an error symbol, your Windows operating system provides sufficient SCSI support.
      • If you experience any problems operating your Epson SCSI scanner; the scanner is not listed in Device Manager; or the scanner is listed with an error, click here to open the scanner troubleshooting article.
      
      
   4. If the SCSI Controllers or SCSI & RAID Controllers device category does not exist, the system does not provide sufficient SCSI support. It indicates that either a SCSI add-in card is not installed on the computer system, or the SCSI card is not detected.
      • If you know a SCSI add-in card is present on the computer system, make sure the SCSI card is installed securely in the expansion slot on the computer system motherboard.
        
        
      • If the SCSI & RAID Controllers category is still missing from the Device Manager, you could try installing the SCSI card in a different slot on the computer system motherboard.
        
        

        Caution:

        It is important that the computer system is unplugged from the power outlet when installing any add-in card on the motherboard to prevent electrical shock and possible damage to the computer system. For information on how to check/install the SCSI card, refer to the documentation that came with the SCSI card or your computer. As this problem may be related to the BIOS, Windows, or hardware we recommend that you contact your PC vendor, the manufacturer of the SCSI add-in card, and Microsoft for further support.

      
      

      If the SCSI controller is listed with an error, refer to the table below.

      Device Manager uses the following symbols to provide information about a particular error condition with a specific system device:

      
      

      Symbol	Definition
      	Indicates the device is in a problem state. A device that is in a problem state can be functioning. A problem code explaining the problem is displayed for the device.
      	Indicates a disabled device. A disabled device is a device that is physically present in the computer and is consuming resources, but does not have a protected-mode driver loaded.
      or	Indicates that Windows was unable to locate the drivers for the device or the driver is not available. If listed under  Other Devices, Windows may not be able to determine the type of device attached to the computer.
      	On a device resource in Computer properties, indicates that the Use Automatic Settings feature is not selected for the device and that the resource was manually selected. Note that it does not indicate a problem or a disabled device state.

      
      

      You could use the Troubleshooting Wizard, if available, to help you diagnose and fix the problem.

      1. Click on Troubleshoot in the device Properties. This will start the Troubleshooting Wizard.
      2. Follow the on-screen prompts and once completed, open the device Properties again and check the Device status area.
      
      

      If, after troubleshooting, the SCSI Controller is listed and identified in Device Manager without an error symbol, it should be ready to use with the scanner.

      • If you experience any problems operating your Epson SCSI scanner; the scanner is not listed in Device Manager; or the scanner is listed with an error, click here to open the scanner troubleshooting article.
      
      

      If, after troubleshooting, the SCSI Controller is still listed with an error or not identified, we recommend contacting your PC vendor, SCSI card manufacturer, or Microsoft for support. If you continue to experience problems with SCSI interface, you may need to check the configuration of the SCSI card BIOS. Contact Adaptec for support.

      If you experience any of the following problems, you may need to investigate a possible IRQ conflict:

      • The scanner and another device not working (a peripheral such as a printer, or another device such as a disk drive, interface card, modem etc.)
      • The computer freezes up.
      • The computer does not boot into Windows.

      When the computer boots, a unique IRQ (interrupt request) is assigned to each hardware device that requires one. A device requires an IRQ if it can initiate an action or provide input to the computer. The SCSI card will be assigned an IRQ, as are devices such as your disc drives, mouse, and keyboard. The IRQ uniquely identifies that device as well as the software that controls it, and this is used by the computer. Some IRQs are reserved for specific device types, others are available for Windows to assign. Devices can share an IRQ in Windows without it causing a conflict generally as long as they are not used at the same time. If another device is sharing the same IRQ number, and both attempt to send information to the computer/are used at the same time, it will likely cause a conflict.

      See the following Microsoft articles for IRQ support information:

      • Windows XP: 314068
      • Windows 2000: 252420

   USB Scanners / Printers:

   
   
   
   
   

   1. In Device Manager, locate Universal Serial Bus Controllers.
      
      

      Note:
      If the USB Universal Host Controllers device category does not exist, your Windows operating system does not provide USB support. No further troubleshooting is necessary at this point. In the event of this, contact your dealer for advice. Contact your PC vendor or Microsoft for support.

      
      
   2. Click on the [+] plus next to Universal Serial Bus Controllers, then check if the USB Universal Host Controller is identified (i.e. a manufacturer is named e.g. Intel, VIA, SiS, Nvidia, ALi).
      
      

      Figure 1: The USB Host Controller is identified as 'Intel (R) 82801GB':

      

      
      
   3. If the USB Universal Host Controller and the USB Root Hub are identified your Windows operating system provides sufficient USB support.
      
      

      Note:

      There are known issues with the Via/Via Tech USB Controllers that may affect the detection, installation and communication of the scanner / printer with the computer. Microsoft released updates in the Service Packs, for both Windows 2000 and XP so ensure that your system is fully updated. The latest updates can be downloaded and installed through the Windows Update or Microsoft Update tool, available from http://windowsupdate.microsoft.com.
