Envelopes or tapes are not sealing or only partially sealing.


The system may be low on sealing solution, or there may be an issue with the moistener brush.


Follow these steps to correct problems with sealing envelopes:

If an 'Out of E-Z Seal' message is displayed:
  • Make sure that the sealer bottle has fluid.
  • Make sure that the sealer bottle is seated properly in the holder.
Note: The bottle should make a "glug" sound when it is seated properly.

Check the brush:
  • Connect® +500W, 1000, and 2000 / SendPro™ 1000, 1500, and 2000: Press the blue button on the feed deck, then pull the brush out.

  • Sealing tapes with the optional tape moistening unit on the Connect+® 3000 / SendPro™ 3000: Put the blue lever nearest you to the right and pull the brush assembly out.
If the moistener brush is dry:
  • Make sure the sealer bottle/moistener has fluid.
  • Make sure the sealer bottle is installed correctly.
Note: An incorrect installation can keep the brush from contacting the wick properly.

If the moistener brush is dirty:
  • Remove the moistener brush.
  • Clean the moistener brush with plain water and rinse it thoroughly.
  • Reinstall the moistener brush.
If the glue is slow-acting:
  • Remove mail from the drop stacker.
  • Examine mail pieces and ensure that each envelope flap is seated flat against the body of the envelope.
  • If necessary, tap the mail on the table to ensure all the mail pieces are even with each other.
  • With the mail facing you, run your hand across the top of the stack while squeezing the stack together. Repeat this process as needed.
  • Allow the envelopes to dry undisturbed.
If the issue is still not resolved, contact Technical Support. Please have your model and serial number ready, to find this select Settings > Hardware > General.
