Note: DM900 series:  if AutoStart is enabled, select all options before you place envelopes on the feed deck.
  1. Move the side guide close to the edge of the envelopes, leaving about 1/16 inch clearance  (DM900 series: The side guide is optional and not required)
  2. Position the backstop:
    • Up for letter size
    • Down for larger size
  3. Move the thickness adjustment knob to accommodate the envelope thickness:
