Cant figure out how to enlarge a copy on fax...

Hi,
To select the resolution Select the desired resolution according to the type of document.
“STANDARD”: For printed or typewritten originals with normal-sized characters.
“FINE”: For originals with small printing.
“SUPER FINE”: For originals with very small printing. This setting only works with other compatible fax machines.
“PHOTO”: For originals containing photographs, shaded drawings, etc.
Using the “FINE”, “SUPER FINE” or “PHOTO” setting will increase transmission time. If the resolution setting is changed during feeding, it will be effective

If you go to:

You will find the online manual for this machine.
Hope this will help you...
