4Flex a stack of envelopes back and forth and then straighten the edges on a level surface. Press down the corners to flatten them.
Fan the envelopes. This prevents the edges of the envelopes from sticking together and helps them feed properly.
Note: When you load envelopes, do not exceed the maximum stack height of 64.7 mm (2.55 in.). The envelope feeder holds a maximum of 85 envelopes (75 g/m2, 20 lb bond).
