Fax Feature Is Not Operating - HP LaserJet MFP Analog Fax Accessory 300 Guide

The LED on the fax accessory illuminates after the MFP boots This
LED remains on, but may turn off for a brief period (one second) after
a fax is sent or received. If the LED fails to illuminate by the time the
printer is ready, it could indicate a fax accessory malfunction or that
the fax accessory connector is not properly seated in the formatter fax
connector, or may have bent pins.
If the LED fails to illuminate after a few seconds, either the fax card
is not installed correctly or the fax card has failed and should be
replaced.
