Sealing issues on the DM400 and DM475
Sealing issues on the DM400 and DM475
Products affected:
DM400c / DM475c (G920, G925)
DM400M / DM475M (G922)
Issue
Envelopes are not sealing or only partially sealing.
Cause
The system may be low on sealing solution, or there may be an issue with the moistener brush.
Resolution
Follow these steps to resolve these possible sealing issues:
Low Sealant
Make sure that the sealer bottle has fluid.
Make sure that the sealer bottle is seated properly in the holder. It should make a 'glug' sound when it is seated properly.
Dry Moistener Brush
Make sure that the sealer bottle/moistener has fluid.
Make sure that the sealer bottle is installed correctly.
Make sure that the grate is installed correctly.
An incorrect installation can keep the brush from contacting the wick properly.
Wet the moistener brush with EZ
Seal.
If the brush dries out quickly, replace the moistener wick.
Dirty Moistener Brush
Remove the moistener brush.
Clean the moistener brush with plain water and rinse it thoroughly.
Worn Moistener Brush
Replace the moistener brush.
Glue is slow-acting
Remove mail from the drop stacker.
Examine the 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.
