Question about Canon CanoScan D660U Flatbed Scanner

My CanoScan D660U is not powering up when i plug it in

I've been using my CanoScan D660U for several years without problem. When not in use, i disconect the power & usb cables and store it away from my desktop. The other day i went to plug it in so that i can do some scanning but when i did, the light that usually comes on did not come on. My PC recognized that the scanner had been connected but i was not able to get it to scan regardless of what I did. I called the Canon help desk and they walked me through the process of uninstalling and reinstalling the drivers but that did not get the scanner running. Given that the power adapter is always plugged in; I thought that it may have been damaged by a power surge so I brought it to the shop where i bought the scanner and had them run a check on the adapter. The technician tested the adapter and said that it was sending power down the line (exactly how much power he did not say). So that's it for now. I was thinking of getting a general technician to take a look at it. Anyone out there have any idea of what the problem could be and how i could resolve it? I like this machine and would like to continue using it if i may. Regards, Orkosan

Re: My CanoScan D660U is not powering up when i plug it...

Image scanners use a bright light (usualy LED's but sometimes fluorescent) to get the image. If that is the "light" that didn't come on, it may need replacing. If the "light" is a power indicator, a surge might have fried the circuits. Service on consumer products is often impossible to do yourself and sometimes more expensive than a replacement. Try a Google on your scanner # and "disassembly" if you feellucky and are handy with tools. Best bet: replace it.

We have moved house and have misplaced our powerlead for the CanoScan D660U

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

You can google Canon and locate a local dealer in your area to purchase a replacement power lead or you can go on Ebay and purchase one on there and it will probably be cheaper on Ebay then from a canon dealer.

I hope this helps you out.

If the light is not illuminating when positioning the lamp and the scan button turns grey (inoperative) the light source has probably failed in the cover. It is integral with the cover. Costs about $160 AUD to replace.

Vista 64 bit

The D660U is not supported in a 64 bit OS. Only the 32 bit version of Windows Vista is supported. You can get that driver here:

Let's face it, the D660U was released in September of 2000. That's nearly 7 years ago. You can say "Shame on all vendors" all you want. However, I'll bet that the computer you have Windows Vista64 running on is not the same computer you had when you bought the D660U. It's time to upgrade. The CanoScan 8800F is a great scanner. Amazingly fast too! Zero warm-up time.

Good luck.

Power problem?

Ensure it is plugged in all the way. Do you have a meter to measure the voltage out of the Powersupply? it should be 12VDC. I would expect some sign of life even w/o the USB connected..

Not a mac person so this may/may not be relevant from the user guide

• iMacs running Mac OS 8.5 or 8.5.1 require a system update.
Please see Problems with the Scanner in the Troubleshooting
section of the CanoScan Setup Utility CD-ROM.
