Dear Sonya1:
I have a question of your instructions.
"Before you connect your MF4370dn( -> MF4350d) to your Windows 10 computer, you can download and install drivers and software for your printer by following the steps below."...........................
"8. Connect the USB cable and allow the installation to complete." ................................
The above 2-instruction means:
The USB cable, connecting-printer-and-pc, is to be connected during the midway, step 8. !!!
In the past, the USB cable is connected/used while finishing installation of both, printer and toolbox, software.
Now the software installation is changed.! Right?
