Unimessage Pro and Pro LAN software bring together 
fax, Internet fax, e-mail, printing, copying and scanning to
provide fully integrated messaging right on your desktop.

Enjoy the economic benefits and
convenience of fax-to-email with the
IFax upgrade. 

With the OKI IFax upgrade, you can send
paper documents as .tif or .pdf attach-
ments to an e-mail address, a group 
of addresses, or a combination of fax
numbers and e-mail addresses. 

Recipients can retrieve their faxes from
wherever they have access to e-mail—
rather than having to look for an actual 
fax machine.
