Out of E-Z Seal message

Note: The bottle should make a "glug" sound when it is seated properly.

Check the brush

  • SendPro 1000, 1500, and 2000: Press the blue button on the feed deck, then pull the brush out.
  • Sealing Envelopes on the SendPro 3000: Lift the jam release out of the way, then lift the blue handle on the feed deck. The brush assembly will then slide out.
  • Sealing tapes with the optional tape moistening unit on the SendPro 3000: Put the blue lever nearest you to the right and pull the brush assembly out.

Note: An incorrect installation can keep the brush from contacting the wick properly.
If the moistener brush is dry follow the same steps as Out of E-Z Seal.

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.
