Send a fax to 0000
This will send a fax to itself, therefore if you want to test:
Fax forward to email
Print conformation sheet
What tray, type of stock it prints on and the output tray
This will save the need to get someone else to keep sending a fax, or using myfax.com etc.
The main incoming fax line still needs using to ensure the fax functions correctly, but that only needs to be done once after completing a self test to 0000
