I am running Windows 7 Home Premium. I have a Canoscan LiDE 20/N67OU/N676U connected . It fires up on reboot or start. The scanner will work by using "Irfan" or "Faststone"image viewers but does not work by going into 'Devices and Printers' and using the right click on the Scanner icon and clicking "Start Scan' it then gives me a message showing "You need WIA driver to use this device. Please install it from your CD or Mfrs. website and try again" well for one thing the CD does not have any drivers on it and states this on the label , and secondly I have been to dozens of Websites and after downloading various drivers from 'Canon' etc. including what they call WIA driver it still doesn't work . I have checked the troubleshooter out and it keeps telling me that the most suitable driver is fitted . Why is it so ,that it will work when using a third party app. like 'Irfan' or 'Faststone' but not the inbuilt system. any ideas please Guys?
There are 2 things going on here.
The first is a 32bit/64bit problem - the drivers you have are 32-bit and I'm guessing you have Win7 64bit. WIA stands for Windows Image Acquisition and when you click on the device directly you are asking Windows to use WIA to communicate with the scanner, which is can't because the drivers aren't 64bit.
The second is Faststone and IrFan are using their own imaging routine that does not call on WIA for assistance, which is why it works.
You have two options: 1) continue to use FastStone and IrFan for scanning. 2) I've seen some have good results by downloading the [url=http://usa.canon.com/cusa/support/consumer/scanners/canoscan_series/canoscan_lide_20#DriversAndSoftware:ajo29efr]driver only[/url:ajo29efr] (release in Oct 2009), extracting the files from the exe and manually updating the driver through the device manager.
I know it's not much help, but good luck!
Bloody hell Dave that reply was extra quick ,don't you sleep?.....It is a 32bit system so I guess it's back to the drawing Board ,but I think I am chasing my tail so I will just have to use one of the third party apps ....It was only a matter of convenience any how !...BTW I am about to place another Post about disabling the Touchpad on HP Presario C550 machine.Cheers ejgippy
EJ - The installed driver for the Canoscan is most likely a generic MS driver.
Why don't you try what Dave has suggested and download the manufacturer's [Twain] driver from Canon........via the link Dave has supplied. Pretty sure that will do the trick.
Cheers mate....Jim
Yeh Guys I did try that suggestion but no go still wants a WIA driver , well I have fed it about six so far pus the Scangear driver , in fact its got more drivers than Tiger Woods or the Grand Prix....Cheers ejgippy
Hi,
Just a very wild guess, could this have somthing to do with a service that's not working properly?
I am human
It is possible that the Windows Image Acquisition service has been set to Disabled or Manual. Changing the startup type to automatic would correct that.
Good point guys. Although, if that were the case, I would have expected a different error message than the one reported by EJ in the original post.
Anyway, EJ you can check the status of the WIA service: Click [b:37l8lz0p]Start[/b:37l8lz0p] and type [b:37l8lz0p]services[/b:37l8lz0p] into the search dialogue box, then click on "Services" in the results (it will be the one associated with an icon representing a couple of little cogs).
In the Services window, scroll down to Windows Image Acquisition and check the status. If it is set to Disabled or Manual, change it to Automatic.
Hi all , I am not great on services but I have had a look and it was set to Automatic , but going on from there I opened the next box "Log On" ... I notice that 'This Account' [ Local Service] is checked followed by a password [hidden] as long as your arm , the 'Local System Account' is unchecked as is the box associated with it which reads "Allow service to interact with desktop" ?......I am not sure but there seemed to be some bad kharma in there ,so I got out quickly ....ejgippy
