The fax icon disappears from the home screen even without any changes. This may happen for the device that has been turned on for a longer period such as more than 30 days. In the printer Embedded Web Server (EWS), see Settings > Fax > Fax Setup > Fax Transport it is set to none and no option for analog.
When you reboot the printer, the fax icon will be visible again but this is just a work around and the issue may happen again.
This is a known issue in firmware FW7.0 and have been fixed in firmware FW7.2 or higher.
Check xref_TE363_xref for the latest PE firmware release.
