Attaching the Envelope Feeder

Pull out only one paper tray at a time. Having multiple paper trays fully extended could cause the printer to fall over.
The printer can accommodate two optional paper feed units. The envelope feeder can be used with "Tray 2" and "Tray 3". The main unit's feed tray (Tray 1) cannot be used for this purpose.

This section describes the procedure to install the envelope feeder unit using Tray 2 as an example.

Check the package contains the following:
Pull out the optional paper tray (Tray 2) from the optional paper feed unit until it stops. Then lift the front slightly and pull it out completely.
Lift the front of the envelope feeder, and slide it carefully into the paper feed until it stops.

This unit is a tray that slides into the optional paper feed unit. Without the optional paper feed unit, this envelope feeder cannot be used.
Keep the removed paper tray with paper in a cool dark place.
