You can seal envelopes whether you are printing postage on the envelopes or only sealing the envelopes (no postage).
- Check the level of sealing solution by checking the sight window on the front of the feeder deck.
- Place the envelopes with the flap side facing down and the top edge against the rear wall.
- Make sure the seal/no seal lever is set to the seal position (all the way to the left).
- Place the envelopes on the feed deck and tap the Start button on the Print on Envelopes screen.
Note: If the moistener tank is full and your envelopes do not seal correctly, clean or replace the moistener brush and wick.
