How do I check and manage fax time, date, and header information in my HP LaserJet Pro MFP series printer?

To configure this setting via control panel: Press Setup > System Setup > Time/Date for clock selection and entry; press OK after inputting values. For the header settings, select Fax Setup > Fax Header to enter the fax number (max 20 characters) and company name or header text (not exceeding 40 characters).
