Set the correct paper type for the tray that contains the paper specified for the cover or insert. If the paper type set for the cover or insert is not the same as the paper type set for the tray, paper will be fed from a different tray. ➞ System Settings > "Paper Tray Settings" > "Tray Settings" PROBLEMS RELATED TO PERIPHERAL DEVICES Problem The connected USB device cannot be used.
