Preparations and Orientation for Loading Envelopes

As envelopes have a different shape and thickness from regular paper, preparations must be made before loading envelopes.
Envelopes can be printed only on the front side (non-glued side). Load the envelope in the multi-purpose tray, taking care to check the orientation of the envelope and that the correct side is facing up.
For the general procedure of loading envelopes in the multi-purpose tray, see the following:

Preparations before Loading Envelopes

Align the envelopes regardless of the number of envelopes to be loaded.
Close the flap of each envelope.
Flatten them to remove any air, and make sure the edges are pressed tightly.
Loosen any stiff corners of the envelopes, and flatten any curls.
Align the edges of the envelopes on a flat surface.
The envelopes are ready to be loaded.

Orientation of Envelopes

Insert the envelopes No. 10 (COM10), Monarch, ISO-C5, or DL from the short side with the front side (non-glued side) face up. Insert the envelope with the flap closed and on the left side.
