How do I set the date, time, and fax header on the M1530?

Press the Setup button on the control panel, navigate to System Setup > Time/Date, then select either a 12-hour or 24-hour clock and enter the current time and date. To set the fax header, navigate to Fax Setup > Basic Setup > Fax Header and enter your fax number and company name. The fax number allows a maximum of 20 characters, and the company name allows up to 25 characters.
