Mfc-8220 fax very slowly

[canactech]

I have a problem with a Brother MFC-8220. When a fax with many pages is send, the time for each page is very long. An example: to sned 30 pages it could take 45 minutes. I've replaced the fax by another one and everything is fine. I've checked the configuration and everything look normal.

Do you have any idea to accelerate the process of sending faxes.

Thank you.
