Products affected: SendPro® C, SendPro®+ (8H10)

This procedure describes how to seal envelopes whether you are printing postage on the envelopes or only sealing the envelopes (no-postage).

  1. Check the level of sealant in the moistener tank and add more if required.
  2. When feeding an envelope, be sure to slide the envelope flap under the edge of the feed deck, so the moistener can wet the flap.
