I am getting an error code 20-547 "The available fax memory is running low." I will be able to fax incoming/outgoing until the error code turns into "The available fax memory is full". I have reset the machine. Unplugged it and updated the software but it still gives me the first error code. How do I go about clearing up the available fax memory? I've tried to look up info but cannot find anything on THIS particular machine. Any info would help. Thanks!
