We did not receive a plastic bag with instructions. We also found no label other than the serial number on the device.
Kyocera Ecosys MA3500CIX

What can we do here?

In the plastic set with the many instructions there is a label (approx. 10x4cm) with the necessary information on it.
My tip: Stick this label on the manual feeder when you open it. It is best protected there and won't get lost.
