I use iMac with OSX 10.9.2. I installed latest version of MF Toolbox, upgraded the firmware to 15.04. I can scan with USB. Wireless works because I can print with wireless. However, when I disconnect USB and try to scan through wireless network, either from iMac or from MF4890dw, it will scan the first page and hangs for a while, then MF2890 will show "An error has occurred [close]" and the computer will pop up an error window:
"Cannot communicate with the scanner.
The cable may be disconnected, or the scanner may be turned off.
Check the scanner status and try again.
Scanner driver will be terminated.
Error code: 200010"
MF4890dw is communicating with iMac because it will scan the first page and it will tell me to put paper in the feeder.
Any help is appreciated.
I know this error is frustrating and I will be glad to assist you.
I recommend uninstalling and reinstalling the ScanGear driver and the MF Toolbox software.
Please follow the instructions below to uninstall:
Next, reinstall the Scangear driver, and then add the scanner in the MF Toolbox [Network Settings], by following the instructions below:
