Resolve Error 372A on the DM400C, DM450C and more

Products affected: DM400C™, DM450C™, DM475™


The meter displays error code 372A and will not run mail.


There is a possible jam in the meter.


This error can occur for two reasons:
  1. The mail piece is too long. The maximum length of an envelope is 15 inches (14 inches for the DM475™ running in WOW mode). Make sure that the envelope is not longer than this.
  2. The meter is jammed:
    1. Open the top cover and all jam release levers.
    2. Remove any mail pieces in the machine.
    3. Blow out the mail path with non-flammable compressed air to remove dust and debris.
    4. Close all jam release levers and the top cover.
If the issue is still not resolved, contact client support. Please have your model number ready.
