Light stays on all the time

I have had problems with the scanner light staying on sometimes. I downloaded/installed the latest driver and not the light stays on all the time. Is this a problem with because of Vista or is it the scanner software? I have to unplug the scanner power when I am not using it.

    Thanks, this might be a fix except I haven't a clue how to open the twain driver. I have searched through the help screens in Vista and looked at the device manger but no where can I find any place to open it.

    Well I'll be darned. I spoke too soon. I found the driver through Photoshop. All the years I've used a scanner and I didn't understand this simple thing. Thanks spammster, you taught me a lot with your answer. -Ron

Open the twain driver,

go to preferences and set the timer for the light shutoff.

it is probably set to something high.

remember though: when the light goes off, the lamp needs to heat up again

I have a canonScan 8400F there's a connection with computer however when i open adobe photoshop there's no preview..


I have many years experience repairing Canon scanners so here is my suggestion for you.

I guess I have a couple of questions for you first. Does your computer recognize the scanner is attached to your computer? If so can you scan in any other program like Windows Paint? If you say yes to both of these then the problem is with configuring your adobe software. If you say no then we need to go back to basics. I would google Canon Canoscan 8400F Drivers, it should pull up a page that will take you to Canons official website. Download the latest drivers from Canon's official website,the drivers are dated and the ones towards the top should be the latest drivers. The drivers are free. Also while your there download the newest version of Capture Perfect its a utility program for scanning its free also but download the latest one. Now make sure your scanner is unplugged from your computer, the cable that goes from the scanner to the computer. Install the latest drivers on to your computer. Once they are installed, then with your scanner powered on attach the cable from the scanner to your computer. A window should pop up saying a new device (or drivers) is being installed. Once this completes reboot your scanner and you should be able to scan again.

I use Paint shop and in order for me to scan with my Canon scanner I need to go to aquire and image, from a scanner or camera, and then it controls the scanner and does the scanning for me.

I hope this helps you out.

Scanner has racheting noise and red light stays


This noise is caused by the transport lock. Power the scanner off. Lock and unlock the transport lock a few times and then leave it in the unlocked position again and power on.

The copy light won't stay to copy


That is often an un-fixable problem. However, sometimes a fully charged fresh set of batteries will handle. (Use high-quality rechargables, not disposable alkalines.) Also try power cycling the unit several times.

Panasonic kx-mb781


Either go to driversguide.com or go to panasonic's website and request the latest operating specific driver for your Panasonic kx-mb781 scanner. Download the driver and install it. It may be necessary to uninstall the old driver first. Also, try to obtain the operating and maintenance manuals for the scanner from panasonic. If you don't already have it. If you spend a little time surfing the two suggested websites you should be able to resolve your problem. Get back with me if you still have problems.

USB connection fails


Hi, There shouldn't be any problem really. A couple of things you can try: 1. Verify that you have SP2 in the new Dell; 2. Verify that you have USB 2.0; 3. Verify that all your USB are enabled in your CMOS/BIOS; 4. Un-check "Allow computer to turn off this device to save power" in your USB Power Management; 5. Try other USB ports (front/rear). Hope this be of some help/idea. Post back how things turns up or should you need further information. Good luck and kind regards.
