Avoiding envelope sealing issues on the SendPro C, SendPro+

Print this support article
Products affected: SendPro® C, SendPro®+ (8H10)

Sealing issues can be caused by:

  • not enough sealant in the moistener tank
  • not placing the envelope correctly on the feed deck
  • problems with the moistener brush or wick

Use this checklist to avoid envelope sealing issues:

  • Check the level of sealant in the moistener tank and add more if required.
  • When feeding an envelope be sure to slide the envelope flap under the edge of the feed deck. Otherwise, the moistener cannot wet the flap.
  • If the moistener tank is full, and your envelopes are still not sealing correctly, clean or replace your moistener brush and wick.
