I have multiple computers in my office, and the same problem on every single one. Printer is connected to LAN by WiFi, all computers use WiFi and all computers can print. But scanning is only possible for max couple of weeks after driver reinstall. We have all Win10 computers.
I used packet sniffer, and when I tried to start scanning from the computer there is no communication whatsoever - not a single packet originates from the computer to the network as if the application assumed the scanner is disconneted.
When I try to scan using Cannon's scan button there is communication with the computer, Cannon MF Toolbox is initiated in the user's computer, but after 10-20 secs the error occurs (on printer's LED screen). In network communication I've seen some packets identified: Name Query Response NBSTAT [Malformed Packet] , I am not an expert in networking to interpret if it is a source of the problem, but bacause these packets are sent as the reply to the computer's request it may indicate what is happening.
Can you solve the problem? I cannot reinstall drivers for all workstations every month or so.
