Pitney Bowes DM300c 用户手册

Differential weighing is an option that is available on certain models 

in the DM300c and DM400c series. 
It allows you to process mixed mail using the weighing platform 

(scale). Put a number of pieces of mail onto the weighing platform. 

The system calculates the postage for each piece of mail you 

remove from the weighing platform automatically.
1.  Make sure weighing platform is activated (you will see 

“

scale 

weight

“

 and 0g on the display). See Chapter 6, System Optons 

to turn your scale on if necessary.

2.  Select the desired carrier, then select the class of mail required 

(use the scroll keys to see additional classes).

3.  If there is no value next to the class name, more information 

is needed. Follow the prompts for the options and/or services 

available for this class of service.  

4.  Press 

Enter when finished entering all the class options and fees.

5.  Press the 

Weigh/Rate key.

6.  Select “Differential Weighing”.
7.  Place the mail pieces onto the weighing platform. They can be 

placed onto the platform in a container, if required.

8.  Remove the first mail piece and the value will automatically set. 

Process this mail piece in the normal way.

9.  Continue removing mail pieces and processing until the last 

mail piece is reached. When the last piece (or mail container) is 

removed from the platform, you will be asked to “Print Postage 

for last item removed”. Select “Yes” or “No”.

10. You can now place more items on the platform to continue using 

the option or select “Exit Differential Weighing”.
