Loading Envelopes

Make sure to flatten any curls on envelopes before loading them. Also pay attention to the orientation of envelopes and which side is face up.
This section explains how to load envelopes in the orientation you want, as well as preparations that you need to complete before loading envelopes. For a complete description of the procedure for loading envelopes in the multi-purpose tray or manual feed slot, see the following.

Before Loading Envelopes

Follow the procedure below to prepare the envelopes before loading.
When loading in the manual feed slot, only one envelope can be loaded at a time. Note that the preparations described in steps 1 to 3 below are necessary.
1
Close the flap of each envelope.
2
Press down to expel air from the envelopes and make sure that the folds on all four sides are sharp and that the stack is flat.
3
Remove curls by flexing the stiff sections at the four corners.
4
Tap the stack on a flat surface to even the edges of the envelopes.
 

Loading Envelopes in the Multi-Purpose Tray and Manual Feed Slot

Load the envelopes Monarch, No. 10 (COM10), DL, or C5 in portrait orientation (with the short edge toward the machine), with the non-glued side (front side) face up. You cannot print on the reverse side of envelopes.
When loading in the manual feed slot, only one envelope can be loaded at a time.
Load the envelopes so that the edge with the flap is toward the left side as shown in the illustration.
