Hi @ali_al , I can help you with the fax not being able to send faxes.
Check these settings on the printer:
Confirm the fax number:
Go to setup, fax setup, advanced setup, confirm fax #.
Turn off error correction:
Go to setup, service, fax service, error correction and turn if off.
Set the fax speed to medium:
Go to setup, fax setup, advanced setup, fax speed and select medium.
Turn off the private receive:
Go to setup, fax setup, advanced setup, private receive. Turn it off.
Test the fax.
I have provided a document with some steps to try to see if that will resolve the issue.
Cannot Send or Receive Faxes.
Please provide the following information so I can assist you better.
What type of connection do you have? (Analogue, DSL, Cable Modem)
Are you using the 2 wire phone cable?
Do you have distinctive ring set up on the line?
Is there any voice mail set up?
Do you have a answering machine? (Where is it connected to?)
Where is the fax cable connected to? (modem, wall jack)
Is there a phone also connected the printer?
