Select anywhere within the envelope on the Run Mail screen. You can also select the Edit envelope link.
If your system has full color capability there will be 3 color filter buttons located directly under the image list.
By selecting one of the filter buttons you can choose to display only those messages that are in color, mono (black), or postal red. If your system has a mono and postal red printer, there will only be 2 filter option buttons. Systems having only the postal red printer do not have any filter option buttons since all the messages/addresses are postal red.
