I have tried EVERY "fix it" I've found on Google and nothing is working. I've changed my computer to Power Saver battery option -- didn't work. Changed the suspension on the USB port...didn't work. Yes, I'm using a 3.0 USB port on a Dell Inspiron 17 5000 series laptop. I have Windows 10 and I think that's the #1 problem --- Windows 10.
I've installed two different drivers that's supposed to work... didn't. I've installed it via the CD-ROM, didn't work...uninstalled and re-installed via the website... didn't work. Nothing is working.
Should I just return the scanner and go with a different brand of product? I already have trouble with my Canon MG3500 series printer so.. I should have known better than to buy a Canon portable scanner.
Since the LiDE 400 uses the USB connection both for communication and for power, try plugging in the laptop to external power when using the scanner. Usage of the USB connection when running on battery power can reduce the electricity (and thus also the USB signal strength).
My problem is slightly different in that I am not using a laptop and so your suggestion is of no help to me. Also it was working fine for months and I was in the middle of scanning and it just stopped.
I finally returned my LiDE 400. Hoping they fulfill a refund. It just absolutely was not compatible with Windows 10, no matter what they said. I even posted a review telling others with Windows 10 to steer clear of the product and of course, they deleted it. I've had it with Canon.. the customer service has been horrendous, the products are getting worse as years go by.
Some of the LiDE 400 devices had the scan bar installed backwards and were not caught before they left the manufacturer.
if you plug it in and when it finishes warming up, the scan bar is at the tail end (where the usb connects) this is what the problem is
Return it for exchange if you can or call support and if you still have reciept they will ship a replacement.
same problem here with my LiDE 300: the scan bar at rest is not at the button end but at the tail. I wonder if Canon could confirm this is part of a defective batch and return is for free, even if past the warranty.
I had the same problem and after some experimentation found that uninstalling all the scanning software and drivers and then reinstalling after a reboot my scanner started working again. Hope this helps someone
I have a scanner with the scan bar at the tail end. When I plug it in, the scan bar moves to the front, flashes when going back 1 inch, and then returns to the previous position (tail end). I don't have a warranty on this one and would appreciate any hints. Thanks.
Emails and calls to Cannon technical support have not helped. After two rounds of the typical "reinstall...", they sent some patch, which did not help. This seems to be a known problem in user reports and the Cannon support staff, but no solutions.
It works until the next reboot. I keep the Services app pinned to my task bar with Name sorted in reverse order so I can quickly get to the WIA service. I have uninstalled/reinstalled with the latest drivers and software and nothing else works for me.
Is the scanner connected directly to a USB port on the laptop or motherboard? Since you have already investigated the software route, have you tried replacing the cable and testing on a different port?
Desktop, usb via hub. I don't see how it is hardware, since it works fine always after reboot for a day+, and then fails. I can try moving the connection after a failure, but hardware wouldn't give that symptom i don;t think.
Hi Guthrie. I see that you are getting a TWAIN driver error (80FF0001) when you try to use your imageFORMULA R40 and you have installed the patch we sent you. If you did not reach out to us after installing the patch, please call us at 1-800-652-2666, Monday - Friday 8:00 A.M. - 8:00 P.M. ET (excluding holidays). If you have already contacted us, we recommend that you check with your computer's manufacturer. We have seen that security programs may interfere with the TWAIN driver, so if you have any running, you can contact the company that makes that software. Thanks for your contributions to the community.
I would like to see some logging information from your tool, or some resolution of the actual error message. So far I have only gotten generic responses - Reinstall, try this patch, update, maybe it is hardware (which symptoms do not match), ...
I am having the same problem, however re-booting does not work for me. What did work for a few days was moving the usb cable to another usb port, but now that does not work. So my scanner is useless for now.
I just bought a Canon MG6821 printer/scanner. Although the Best Buy salesperson assured me that it "should be easy" to set it up, I spent an hour on the phone with a Geek Squad person. He got it set up wirelessly. I can print from my iMac (running Yosemite) and from my new iPad Pro. Today I discovered that I cannot scan. The computer cannot find the scanner and vice versa. Another hour online with the Geek Squad was of NO help. They suggest that someone come to my home. For a brand new device! Before I return it, any help would be appreciated. I am a senior citizen who needs EASY directions if there is a fix.
I was NOT able to scan. I called the Tech Support number and a WONDERFUL agent named Nick had me go through a bunch of things untl he discovered that the fix was relatively simple (now, after a total of over 2.5 hours on the phone with Best Buy...). The scanner LAN setting was for my 2G Wi-Fi network and my computer was set to the 5G network. For some reason, the printer communicated with my iMac, but not the scanner. Now everyone is speaking to each other! Thank you, Nick!
I only use drivers from Microsoft. For Windows 10 that is a 32-bit driver from 2006 that uses ksthunk.sys. That is probably the problem. I'm not sure why Microsoft is not using a current 64-bit driver to support Canon MG3620. I assume because that is what works best with Canons firmware?
Follow the steps below to specify the scanner or printer you want to use on your network. If you change the scanner you use with IJ Network Scanner Selector EX, you will also need to change it with IJ Scan Utility. (See the next section below for instructions.)
The IJ Scan Utility main screen reappears. You can now scan via a network connection.
If your scanner or printer doesn't appear, check the following, click OK to close the screen, then reopen it and try selecting again.
After updating to MacOS 14 Sonoma, my Canon PIXMA 8620 scanner no longer works if I select it from Printers and Scanners in System Preferences or in Print Center app. If I select Open Scanner, Image Capture opens and says no scanner selected. To scan, have to open a separate app, Canon IJ Scan Utility Lite. Printing still works as usual.
I tried your solution and found it worked although you have to click several times on the shared button then click on the printer but what a laborious way of scanning compared to the old way. Apple I think you have it wrong again this time!!!
Not sure if this'll help for your Canon, but when Image Capture opens for my Brother MFP, I see "No camera or scanner selected." and have to disclose the "Shared" section in the sidebar to see and select the Brother scanner.
Well I'll be darned! That's the answer. It works! Apple tricked me again. In the Image Capture window the Shared line was grayed out so I never bothered to select it, but it works anyway and I get the whole scanner window just like the old days, but in Image Capture. Well hidden.
"IJ Scan Utility Lite is the application software which enables you to scan photos and documents using AirPrint. You can easily scan such items simply by clicking the icon you want to choose in the main screen of IJ Scan Utility Lite."
Thanks Randall. So far, Canon just shows their new Canon IJ Scan Utility Lite as supporting Sonoma. Told me the disconnect between the scanner and System Preferences and Print Center was an Apple issue. At least I can scan with the Canon app. It's just extra work from what it was under MacOS 13.
Depends on the Canon Scanner. Canon is dropping support for some of their scanners from MacOS. On their website, MacOS V14 cannot be selected as the OS for downloading drivers/software. These scanners still work fine on Windows. I have two of the the LIDE220 scanners. Thought about buying the LIDE400 but still no MacOS V14 support even though this is the latest model LIDE scanner. Others are reporting similar problems scanning with their All-In-One Canon printers.
This was also true for my HP PageWide Pro MFP. Opening up the Shared heading under Devices in the Image Capture box when I clicked scanner in the printer dialog box did the trick for me. Thank you for that suggestion......I'd spent many hours trying to figure out the problem and this was THE ANSWER!!!
Things just got stranger. We have two LIDE 220 scanners, one connected to the last generation Intel iMac and the other to an early 2023 MacBook M2 Pro Max. Found new drivers for Sonoma, installed them on the iMac and the scanner works fine. Tried to download them to the MacBook and they won't download, tried several times including rebooting. So copied the drivers from the iMac to the MacBook, go thru the installation process and the software isn't installed. The install is successful according to the install process but the software isn't installed. Tried multiple times including rebooting to no effect. Went to the Canon Canadian support site and loaded the older 1.5 drivers (the only ones they have available) and they installed successfully, the scanner is working fine.
