Welcome to HP Support Community

Please perform a printer reset

(1) Turn the printer on, if it is not already on.
(2) Wait until the printer is idle and silent before you continue.
(3) With the printer turned on, disconnect the power cord from the rear of the printer.
(4) Unplug the power cord from the wall outlet.
(5) Wait at least 60 seconds.
(6) Plug the power cord back into the wall outlet.
 NOTE: HP recommends connecting the printer power cord directly to the wall outlet.
(7) Reconnect the power cord to the rear of the printer.
(8) Turn on the printer, if it does not automatically turn on.
The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.
Wait until the warm-up period finishes and your printer is idle and silent before you proceed
 

Then update the Firmware from this Link: https://support.hp.com/us-en/drivers/selfservice/hp-officejet-4630-e-all-in-one-printer-series/53050...

Next, Go to Fax settings from the front panel and look for 2-Sided Fax Print option and ensure it's set to ON

Try faxing and keep me posted how it goes

Thank you and have a wonderful day 😊
