WOW
®
(Weigh-on-the-Way) and Shape-Based Rating
(DM475)
When enabled, the Weigh-on-the Way (WOW
®
) feature increases
your productivity because you don't have to presort the mail by
weight before loading the pieces onto the machine. The DM475 has
a special scale built into its deck that can weigh mail pieces on-the-
fly (that is, as they pass along the deck) so the system can deter-
mine the correct postage of each item. You can feed mail pieces
having various weights (1 oz., 2 oz., 3 oz., etc.) into the machine and
the machine will weigh and apply the correct postage to each piece
automatically.
i
NOTE: The maximum length of a mail piece that can be pro-
cessed is 15" when running in non-WOW® mode and 14" when
running in a WOW® mode.
IMPORTANT:
To avoid mail processing errors:
• Do not touch or accidentally brush against the width sensor or
the deck during WOW® mode while running mail.
• Do not tamp the mail on the mail/WOW® deck
• Do not use the mail/WOW® deck as a work surface
In addition, the DM475 has the ability to rate your mail pieces ac-
cording to the USPS® requirements for shape-based rating (SBR).
SBR was created by the USPS® to rate mail pieces based on thick-
ness, length, or width, in addition to weight (see Appendix B- USPS®
First Class Mail® Sizes for the dimensions).
For example, if a letter is taller than 6-1/8", the system will automati-
cally rate the piece as a "flat" (large envelope) category within the
USPS® First Class mail class (which is correct), even though the
piece would have qualified as a "letter" category if it was based on
weight only.
