ImageClass MF641Cw printer tells me to connect the computer before scanning. I had this printer since last year. No major problems until recently. I use the WiFi to connect to the computer. The machine can print perfectly, yet it cannot scan. I also cannot scan to USB.
I tried the Canon Printer Assistant. It showed that the signal strength is 0%. How can this be possible?
The printer can receive data from the Windows computer but not send. It suggests to move the printer or the router closer. Neither have worked.
