Sealing issues on the SendPro C Lite, SendPro C

Issue

The device is not sealing or only partially sealing envelopes.

Cause

There may be inadequate sealant in the moistener tank, or an issue with the wick or brush in the moistener.

Resolution

1. Be sure to slide the envelope flap under the edge of the feed deck. Otherwise, the moistener cannot wet the flap.
   
2. Check the sealant level by looking at the sight glass on the left side of the moistener tank.
   
3. If the sealant level is low, add sealing solution until it reaches the bottom of the fill hole. Do not overfill the moistener tank.
   • If the tank was empty, allow 30 minutes for the moistener brush and wick to get completely wet before trying to use the moistener.
4. Check if the moistener brush is dry. If it is:
   • Make sure that the white thumbscrews on the bottom of the sealer are tight.
   • Try wetting the moistener brush manually.
   • Make sure that the brush is contacting the wick. Lift the wick up slightly so that it contacts the brush.
5. Check if the moistener brush is dirty. If it is, remove the moistener brush, clean it in plain water, and rinse thoroughly.
