My 8600 printer was connected to my home wireless network and worked fine until recently, but it has dropped the network and refuses to reconnect, so I am unable to print or scan anything unless I use a LAN cable to make a physical connection between the printer and router.
The printer can see the wireless network, but the setup wizard fails to accept the WPA2 password that used to work and still works for other computers and devices that are connected to the network.
I have tried resetting the printer settings to factory defaults and I have restarted both printer and router without success.
Please could someone suggest how I might to fix this problem?
Found a working solution on my own after trawling through various internet forums...
Step 1. First thing was to verify that the printer could connect to an unsecured network, which was done by (temporarily) removing network security and the need to use a network password
Step 2. After restoring network security (and killing the unsecured printer connection), the wireless router was set to WPA+WPA2 PSK mode (rather than using the default setting of WPA2 only)
Step 3. One forum suggested that an additional invisible blank space was being automatically inserted at the start of the network password when it was entered via the printers touch screen... so after inputting the correct password characters, the "left-right" navigation arrows were used to move the cursor back to before the first character and the unwanted blank space was deleted
After doing both of these things, the password was accepted and the printer connected to wireless network
