DM400, DM500, DM550 Operating Guide
This option is available if your system is a DM550 with the integrated scale
platform, or has an attached external scale. If you have both an integrated
scale and an attached external scale, you must disconnect one of them in
order to use Differential Weighing.
This option allows you to place all of the mail on the scale at once, then
remove each piece, one at a time and run it through the system. The system
calculates the postage for each piece of mail you remove from the
scale and applies the postage to the piece as it goes through the mailing
system.
Before using differential weighing:
• Set the scale to zero by pressing the Menu key, then selecting
Zero Scale.
• Make sure each piece of mail weighs at least as much as the amount
specified as the differential trip weight during the installation of your
mailing system. For more information, refer to the Set Up the Scale/
Select Rates: Diff Weigh Trip Weight section in Chapter 5 in this guide.
To perform differential weighing:
1. Press the Mode key.
2. Select Differential Weighing.
3. The system prompts you to place the mail on the scale.
4. If you have previously selected a class, go to step 5. Otherwise you
are prompted to select a class. For more information, refer to Section
3, Selecting the Class or Special Service in this chapter.
5. If you are printing on a piece of mail, remove one piece of mail from
the scale, place it on the feed deck and press Start.
If you are printing tapes, remove one piece of mail and the system automatically
prints a tape.
Repeat this process until you have processed all of your mail. When
printing on a piece of mail, you only need to press the Start key for the
first piece of mail.
NOTE: When you remove the last piece of mail from the scale, the system
asks you if you want to print postage. This is in case the last piece you
remove from the scale is the container for the mail.
