How do I set the time and date on my HP Laserjet M1530 Multifunction Printer?

Enter Setup menu via control panel, use arrow keys to select System Setup followed by Time/Date selection for either a 12-hour or 24-hour clock configuration. Enter current details including hours, minutes, am/pm if needed, then move onto date input using keypad again. Customize additional settings as required under fax setup options like header formatting and click save upon completion (pages 15-16).
