1. Check the level of sealant in the moistener tank. Add more if required.
2. Slide the envelope flap under the edge of the feed deck when inserting an envelope. Otherwise,
the moistener cannot wet the flap.
3. If the moistener tank is full, and your envelopes are still not sealing correctly, clean your
moistener brush and wick.
