Running a Differential Weighing Mail Job

Differential weighing is available on your system if it has an attached scale and you have subscribed to this feature. 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.

For larger pieces of mail (large envelopes or packages), you can use differential weighing to have the system automatically print a tape every time you remove a piece of mail from the scale.

Before using differential weighing:

Make sure each piece of mail weighs at least as much as the amount specified as the differential weighing threshold.
Make sure the stack of mail is less than the capacity of the scale. If "Weight exceeds scale capacity" appears on the screen, remove pieces of mail until the message disappears.

Select the Run Mail button on the Home screen.
Select a job that uses Differential weighing or select the Weighing icon.
1. Select Differential weighing.
2. If necessary, edit the Differential weighing threshold.
3. Select the appropriate print option:
  - Auto tape printing - select this option if you have a stack of mail made up of pieces that can't be processed through the system, like packages or thick flats. Each time you remove a piece of mail from the scale, the system will print a postage tape automatically.
  - Auto envelope printing- select this option if you have a stack of envelopes that can be run through the system. The system will automatically feed the envelope and print postage.
  - Envelope or tape printing - select this option if you have a stack of mail that is a mix of envelopes and packages (mail pieces that can be run through the system and others that require tape). Each time you remove a piece of mail from the scale, you will be required to select either Start or Tape to print postage.
4. Place a stack of mail on the scale and select OK.
Select the class of service, for example, First Class.
Remove one piece of mail.

NOTE: Remove each piece of mail in a single continuous upward motion. Do not slide the mailpiece across mail on the scale.
The system calculates how much that piece of mail weighs by checking how much less the stack of mail weighs.
If the destination or ZIP code or country is needed for the piece of mail, the system will prompt you for it.
If you selected the Auto tape printing option, the system will print a postage tape.

If you selected the Auto envelope printing option, place the piece of mail on the feed deck. The system will automatically feed the envelope and print postage.

If you selected the Envelope or tape printing option, select Tape to print a postage tape or place the piece of mail on the feed deck and select Start.
When the last item is removed from the scale, the system asks you if you want to print postage just in case you are removing an empty mail tray.
