Can't Scan on network with MF4890dw

HarryJ — Wed, 26 Feb 2014 01:38:07 GMT

I can print and I can fax - but I cannot get the scan function to work on my home network. It says "cannot communicate" when I run the toolbox. I moved the printer and scanned using a USB cable just fine (changing the settings to turn USB on). But when back on the network - nothing.

I am on Windows 8.1 (64 bit) and I do have another scanner (Epson) plugged in via USB which continues to work fine - but it doesn't have an automatic feed so I prefer to use the Canon.

I installed the latest firmware on the device as well - but no change.

Hi HarryJ!

When scanning over the network with the imageCLASS MF4890dw, you will need to register the scanner in the MF Network Scan Utility. To perform this operation, please follow the steps below:

Click the blue scanner icon in the system tray on the Windows 8 desktop.
Click the checkbox for the MF4890dw and then click [OK].

Next, scan a document, using the following steps:

Verify that MF Toolbox is closed on the computer and press the [SCAN] button on the printer.
Highlight [Remote Scanner] and press [OK]. The screen will show, "Remote Scanner. Waiting online...".
On the computer, open the MF Toolbox and select [PDF].
Click the green [START] button on the [PDF] window. The machine will start processing the scan.

I hope this information is helpful to you. If the error persists, please contact us at 1-800-OK-CANON (1-800-652-2666)

I am having the same issue with my laptop. I have deleted everything, downloaded the drivers and tool box from the CanonUSA.com website and spent 3 hours on the phone with tech support. The drivers are there, it prints and faxes perfectly, it just doesn't recognize the scanner and I don't have a USB cable to try that route. I am running Windows 7 and have no other printer devices hooked up to my laptop.

A supported scanner is not installed.

Please install a supported scanner, and then restart Toolbox.

Hello,

I'm having the same problem, even after trying your above suggestion re adding permissions to run as administrator.

When opening MF Toolbox, the error message is "A supported scanner is not installed. Help!

I have the same problem, and I am on window 10. It happened very recently. I noticed that there appeared some automatic driver installation: a driver mf44scn.inf was installed on 4/12/2016. I think, that was when the problem started.

My printer is working fine, but not the scanner.

Looking forward your help. Thanks

Support for this is awful. I ran Windows 7 with this scanner, now Windows 10, never worked right. Come on Canon.

Please take a look at our new Service Notice on the availability of a patch to address an issue that prevents certain imageCLASS models from scanning as a result of updating to Windows 8, 8.1 or 10.

Canon MF4890DW, wirelessly connected to Mac OSX 10.10.3. System Preferences say the printer is connected correctly.

I CAN Print, however I have to restart the printer every time I want to print, it will not wake up automatically. I have to do this somtimes 3-4 times before it can connect to the printer.

My Biggest issue is I can only scan about 40% of the time. I start MF Toolbox, close, and restart about 10 times before I can scan (if I can ever get it to scan at all).

When I can't scan (60-100%) of the time, I get the following error: "Cannot communicate with any of the scanners.
The scanners may not be connected, or may be turned off."

Please help.

Thank you,

Thomas

Bought a new Mac. Using MacOs 10.12.6. Downloaded MF Scan utility. Printing working fine. When I try to connect scanner- I type in IP address and the error message I get is "The specified scanner is not supported". Is there a way around this?

Apparently the Canon MF Toolbox 4.9 is not compatible with Windows 10. I cannot find any way to access the scanner function of the MF4880dw remotely over the network.
