Select anywhere within the envelope on the Run Mail screen. You can also select the Edit envelope link.
If your system has full colour capability there will be 3 colour 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 colour, mono (black), or postal ink. If your system has a mono and postal ink printer, there will only be 2 filter option buttons. Systems having only the postal ink printer do not have any filter option buttons since all the messages/addresses are in approved postal ink.
