    there is no power button on that scanner and i have loaded and unloaded the drivers twice. it actually scanned to day , when it cant find image i unplug it and then it says it cant communicate w/scanner when i reconnect the cables

    just didnt leave it unplugged from the power long enough. after a 1/2 hour brake it was plugged back in and worked fine. maybe the capacitators needed to totally discharge. all the comments on the site have been helpful, and i will bookmark the site for the frustrating problems that the vendor sites can never seem to help with

    I am having a similar problem. I have had the scanner for a year or so, but today I moved it to a Windows Vista machine (USB). I installed the Vista drivers from the Epson web site, re-booted my machine, and ran the Epson Scan software.

    It did the first scan OK, but when I tried another it sat there for a minute and finally displayed the "Cannot properly communicate..." error box. Unplugging the power (no on/off switch) did not help.

    It seems like it might be a mechanical problem, like something is getting stuck.

    Any ideas or similar experiences?

Yep - I had the same problem. The issue is the cheap USB wire provided by Epson. It's too thin and isn't very well shielded. Use another one and you should be fine (or try keeping the wire away from other wires/sockets).

Hope that helps. :)

Mac or PC? USB or Firewire? Let me know.

I suggest you connect your cables with the scanner power OFF. Then turn it on. You shouldn't have to reboot every time.

I'm assuming you installed the scanner software, right? Let me know.

    If it doesn't have an ON-OFF (mine has a button) does it have a "reset" button?

    You mention "driver that you loaded and unloaded." Is it a driver, or a program (such as photoshop "lite" - or something like that) which Epson gives you so you could manipulate the scans.

    Generally a PC will recognize it - or it won't. A bad (or not thoroughly plugged-in) cable could cause this intermittent behavior. That fact that it works and it doesn't work is odd... leading me to thinks it may be a cable problem.

    If the computer recognizes it INITIALLY, and then it gets DISconnected, it IS possible that the computer wouldn't recognize it when you reconnected it, until you re-booted.

    I am assuming that when you say can't find the image, you mean can't find the SCANNER.

We get a pop-up that says tyhe scanner cannot communicate with the computer. We had just used the scanner a week ago and all was fine. Robert Schneider

First reboot your computer, then check you connection with from the scanner to the computer. By this I mean pulling it out of the scanner if its not permanently mounted on the scanner. Then pull out the computer side and push it in and try to scan. If this doesn't work then if you have another USB cable swap it out with the one on your scanner and try and scan again. The only communication link with your scanner is that cable.

I hope this helps you out.

250 error on documate 510 xerox

Symptom: When scanning you receive an error 250. Cause: This problem can be caused by several different things but is often a driver or communication problem. Solution: Here are several solutions that can resolve this problem:

Solution 1 - Check for communication problems

Using any of the following can cause communication errors:
  • USB hubs
  • Docking stations
  • USB extension cables
  • USB cables longer than 6'
  • Connecting the scanner to one of the computers front USB ports (desktop computer only)
Connect the scanner directly to a USB port on the back of the computer (or side for notebook computers) using a 6 foot or shorter cable.

If you still receive the same error message, try a different USB cable.

Solution 2 - Redetect the scanner with Hidden Devices

Windows Vista, XP and 2000 users
  1. Disconnect the power and USB cable from the scanner.
  2. Click here and select "Run" or "Open".
  3. The Windows Device Manager will open.
    • Click on the "View" menu then select "Show hidden devices".
  4. Click the "+" next to "Imaging Devices". This will show all Imaging Devices previously and currently connected to the computer.
  5. Right-click on the Visioneer or Xerox scanner name and left click on "Uninstall".
  6. If the scanner is listed more than one time, uninstall ALL occurrences of the scanner.
  7. IF you see "?Other Devices" in the device manager list, click on the "+" to view the list of Other Devices.
  8. Right click then left click on "Uninstall" for each occurrence of the scanner. The scanner may be listed as any of the following:
    • USB Scanner
    • USB Device
    • Unknown Device
    • 1200 DPI Scanner
    • (Your Scanner Model)
    • (any other scanners or cameras listed here that you no longer use)
  9. Click the "+" next to "Universal Serial Bus Controllers".
  10. Right-click every listing of "Unknown Device" and select uninstall.
  11. Once all instances have been removed from device manager, reconnect the power and USB.
Windows Me and 98 users
  1. Right-click on the "My Computer" icon on your Windows Desktop
  2. Select "Properties" from the list
  3. Click on the "Device Manager" tab
  4. Find "Imaging Devices" and click on the plus (+) next to it to expand the list
  5. Select your scanner, then click on the "Remove" button
  6. IF you see "?Other Devices", click on the plus (+) next to it to expand the list

    • USB Scanner
    • USB Device
    • Unknown Device
    • 1200dpi Scanner
    • (your scanner model)
  8. Close the Device Manager
  9. Unplug the scanner from the computer and from the power
  10. Plug the scanner back in to the computer and power
Solution 3 - Check for power problems

If the power for the scanner is plugged into a surge protector, battery backup (UPS), or extension cord, plug the scanner directly to the wall.

Solution 4 - Check for conflict with other devices

This error can also be caused by a conflict with another USB device.
  1. Disconnect all USB device from the computer (including the scanner), except for you keyboard and/or mouse
  2. Turn the scanner off
  3. Restart the computer
  4. Once the computer has fully restarted, reconnect and power on the scanner
  5. If the scanner works properly at this time, it means there is a conflict with another device on the computer
  6. It may help to isolate the two items by connecting one of them to a USB add-in card
Solution 5 - Test the scanner on a different computer

If possible, you should try the scanner on a different computer. If the scanner works correctly on a different computer, then the problem is environmental and may be related to your chipset. See solution 6 below.

Solution 6 - Check the computer's chipset

This problem can also be caused by the computer's chipset. To check the chipset:

  1. Vista, XP and 2000 users: Click here and select "Run" or "Open".
    ME and 98 users: Right click on 'My Computer', select 'Properties' then click the 'Device Manager' tab.
  2. The Windows Device Manager will open.
  3. Click on the plus (+) next to 'Universal Serial Bus Controllers'.
  4. This list will include your computer's chipset.

  5. The follow chipsets are known to have communication problems:
    • SiS 7001
    • VIA Rev. 5 or later
    • Open HCD
    • ALi
  6. If your chipset is one of those listed above or it is only listed as 'Standard', you can try updating the chipset drivers.
    • Contact your computer's manufacturer for more information.
  7. If the problem persists, you may need to use a USB add-in card.
    • This is a PCI card that will add more USB ports to your computer.
  8. For more information about USB chipset issues, see

Have you tried a new USB cable or a different port? Are you sure that the ports are on? (You can turn them off for security or power-savings - check the device manager and the advanced settings from the Screen Saver settings page). Does the scanner work on another computer or does a known working USB device work on your computer? Check if there is an update to the USB driver for your motherboard/machine.

Scanners require bi-directional communication with the computer and are very sensitive to any interference with the signal.

I hope this helps.

How can I resolve this issue: Communication Failed. Make sure that the power is on, the cable is firmly connected, and the scanner is not use by another application. For details refer to FUJITSU TWAIN 32...

Normal 0 Disconnect the printer or at least be sure it is turned off. I'd do both and reinstall the CD software program that came with the printer. When the software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud

Canon Scanner Error

Possible Causes:

1. Faulty communication between the scanner and the computer
2. Insufficient power to the scanner


1. Disconnect and reconnect the USB cable from both the scanner and the computer.
2. Ensure that the USB cable is connected directly to the computer as opposed to connecting through a USB Hub or some other USB device.
3. Restart the computer

You might also try a different USB cable.

If the problem persists after performing the steps listed above, then the unit will most likely require service.
