I'm not sure what type of machine it is but I think it's a Brother. It has a separate fax line and isn't connected to a computer or network or anything like that. The machine will receive faxes fine but...

Are you working with a line over VOIP like Vonage? If so faxes can be hard to send and receive because of line condition.
Also, if you have DSL make sure that you have the proper line conditioners in place so you have good line condition.
If those aren't a problem then contact your phone provider to discuss the issue.
