MP470 will not scan, stops midway, says cannot communicate...

Something is wrong with the scanner or communication to the scanner

turn off printer. unplug, replug in, should reset.
go to canons website to troubleshoot.

It won't scan unless it's connected to your computer and you have scanning software running. It needs to know how to scan, how to save and where to save the scanned image.

OK. Vista 64bit, thanks for your reply. Choose that OS in the following Canon support web page, and you will be able to download the OS specific software for your Canon MP470:

Be careful to choose the right driver in your language. Also you may wish to download other optional software, including a manual.

I hope this helps!

The same thing happen to me. I have Windows XP. Try using the Scanners and Cameras Wizard.

Connect the MP470 to your computer, have it on and place the item to scan onto the scanner.

• Go to the Start Menu
• Click on Printers and Faxes
• On the left of the screen there is an area titled, "Other Places"
• Under the Other Places heading, click Scanners and Cameras
• Select the WIA Canon MP470 device(double-click) This should open the Scanner and Camera Wizard.
• Click Next and you will be taken to the Choosing Scanning Preferences screen. Here you can select picture type. If you click the Preview button your device will scan your item and display it in the preview box. Otherwise click Next.
• Click Next to name the file, choose a file format and where to save it.
• Click Next and your device should scan your item.

what OS? probably missing twain driver. Is it usb, parallel, cat 5?

well as i know there is a selection when u r scanning asking u to scan either in black & white or color

did u check that? maybe its switched to the black and white option

Please visit the below mentioned link which is Canon MP470's manual page:

Thank you

The readme says that some USB hubs have an issue.

I was having problems and was connected via a hub. I removed the hub and connected the printer directly to the back of the PC and voila scanning is all good.

ALex.
