My new operating system doesn't recognize my scanner any longer but does do fine with the printer which are both the same machine. How do I fix that? I moved from Mac OX leopard to Mac OX snow leopard. When I open system preference and click on printer and fax, then select scan, then I try to open scanner, I get this message: "failed to open a session on the device" or device not found. When I try to open it from the HP device manager, it tries to open it then shut down. Or it says "Error: scanner could not be initialized because scanner not found. Thanks for helping Louise Dollin

Try reseat the scanner interface cable, including the the flat cables that connects the scanner card and the system board.
If this doesn't fix the issue, often times a replacement of theHVPS ( High Voltage Power Supply) and the scanner control card is recommended.
For further assistance I suggest you contact Lexmark Technical Support.

A quick fix for most communication errors can be achieved by resetting the printer and/or rebooting the PC. Simply disconnect the printer from your computer (if USB connected)> reboot your pc > unplug and re-plug the printer into the power source to reset it. When the printer turns on, reconnect it to your computer (if USB connected). Then try to print again once the computer fully recognizes the USB connection or when the WiFi light on the printer turns solid green (if WiFi connected.).

If that doesn't help, try the steps below:

1. Disconnect the USB cable connecting the printer from your computer.
2. On your computer, go to Control Panel > Printers and Faxes.
3. Delete the Lexmark print object.
4. Reboot computer.
5. Re-brick your printer by pulling out the power supply - black box where the power cord is plugged into on the back of the printer, and re-plug after 30 seconds.
6. When the printer turns on, reconnect it to the computer.
7. Wait until your computer fully recognizes the USB connection. To check, go to Control Panel > Printers and Faxes. If you see a new Lexmark print object in the list, try to print a document to verify that the problem is fixed.

Hi, there are many possibilities why your scanner is undetected by your computer. It can be its logical connection, scanner driver or the scanner itself.

If you have Windows operating system, please check Device Manager. In the Device Manager please check for the following:
1. Any yellow or red X's, question marks or exclamation marks related to the scanner.
2. Under the Category of Imaging Devices - Check for Epson Product name.

If IMAGING DEVICES is listed, test the scanner from PAINT as follows.
If IMAGING DEVICES is not listed then the scanner is not being recognized. Try another USB port or cable until the scanner shows up in the Device Manager. (The scanner must be on and connected in order for the computer to recognize it)
If you see an Imaging Device that points to your Epson Scanner or Unknown Device that has a yellow question mark or exclamation point, you need to update the driver.

Try to scan in Paint to isolate the issue between your computer and scanner.
To scan in Paint, do the following:

1. Click on START > ALL PROGRAMS > ACCESSORIES > PAINT.
2. Click on FILE then select FROM SCANNER OR CAMERA.
3. Choose COLOR PICTURE.
4. Scan.

If it does not work, it is possible your Windows Image Acquisition (WIA) service is not started.

To restart this process please follow the steps listed bellow.

1. Click on Start > Control Panel > Administrative tools
2. Double-click on Services to access the list of available services.
3. In the Services window scroll down to the bottom and double-click on the Windows Image Acquisition (WIA) Service.
4. Select the STOP option.
5. Click the START option to restore the service.
6. Try scanning again into Paint.

If it scans fine, try scanning from the application that you normally use. If you are still unable to scan or receive any error messages, try reinstalling the scanner driver or software.

If you have Macintosh operating system, please check Apple System Profiler if your scanner is properly detected. The reinstall the scanner driver.

If your scanner is still undetected, please contact your scanner manufacturer for any possible driver updates.

Do you have the combo printer that comes with scanner and printer in one machine? If you do, then one installation should work the device as the computer will recognize it as one. If that's what you have, and the scanner still doesn't work, return the machine and ask for a new one.
If you have separate scanner and printer machines, then you should have two installation discs as each should have its own. You will need to install the scanner if this is the case.
Hope this helps.

Hi,

The network setting for the scanner driver may be incorrect. Check the IP address of your scanner and then set the IP address on the scanner driver.

1- The steps of setting the IP address may differ depending on your operating system.

For XP operating system:
Click Start > Control Panel > Printers and Other Hardware > Scanners and Cameras.

For windows 7 operating system:
Start > Control Panel > ... View scanners and cameras.
2- Right click on the scanner icon for your machine and select Properties.

3- Click Network Setting tab and select Specify your machine by address.
4- Enter the IP Address you confirmed from the snanner menu or ask your network administrator and click OK.


Hope this helps.

uninstall the printer software from ur computer restart and the reinstall the same, disconnect the printer while doing all that and the connect the printer to a different usb port bro

Correct. There is no easy solution for this issue. Several of the "older" scanners are no longer supported through the Vista operating system. Why not purchase a new multi function printer, scanner, fax and copier unit.. you will not locate vista drivers either online or from the manufacturer and without them, the scanner will not function. Alternatively, you could also roll back or re-install Windows XP operating system..

Some motherboard or operating systems have problems if you leave usb devices plugged in. They don't recognize that the device is still there and ignore it. These are referred to as "Legacy USB devices". There are a couple of things to try.

Make sure the problem isn't the printer if you can. If you have another computer just plug it in long enough to for the operating system to recognize something has been plugged in.

On this computer giving you the problem. unplug the usb cable and insert into a different USB port. Usually this is enough to "fix" it and make it usable.

Next is to unplug the usb and reboot the computer a few times. Then insert into a different usb port.

Past this point if it still isn't working then you need to go to control panel-system-hardware manager-usb devices and delete all entries under the usb header. Then reboot. This forces the operating system to find all the usb ports and reinstalls the drivers. Then plug in the usb and it should work again.

Your scanner might not work proprietly. Try to take it back to the shop you bought the printer from and report to them your problems.
