Products affected: DM475™


The machine displays error code 37AF and will not print postage.


The mailpiece was too heavy for the Weigh on the Way (WOW) scale.


UPDATED: September 1, 2017
The WOW scale has detected that the mailpiece is over the 16-ounce limit for the WOW mail. If the mailpiece is over 16 ounces, rate the mailpiece using the attached scale instead.

If the piece does not weigh over 16 ounces, check the WOW weight limit:
  1. Press Menu.
  2. Select Weight/Rate.
  3. Press Page Down twice.
  4. Select Wow Wt. Limit.
  5. Select Return to Maxim.
  6. Press Home to return to the home screen.
If the issue is not resolved, contact client support. Please have your model number ready.
