Follow these steps:
1. Lift the envelope pressure plate (1) all the way up.
2. Gently pull out the envelope feeder extension tray (2) until it latches into place.
Note: Even though the envelope feeder extension tray is used to support larger
size envelopes, you will still want to make sure the tray is pulled out and latched in
place. (This helps avoid problems feeding envelopes to the printer.)
3. Press the left guide button and slide it all the way to the left to move both guides.
(This enables you to place envelopes between the guides; you will adjust the
guides later to match the envelope size.)
