Wait until the cleaning page has finished and the printer is in the Ready state.
This could take up to two minutes.

The report basically tells you that your fax attempt failed and gives all the technical settings. To the average user this is meaningless. The print feature for this is normally turned off, but I have seen a few cases where the default was set to print. Under the diagnostics menu, find the T-30 error setting and set it to never. Check the firware on your printer to make sure it is current. Print the configuration page and check the firmware version on the front page. The current version is 48.181.8. There are many modem fixes included with the firmware.
