How do I change the factory default settings on the printer to prevent the "Sleep Mode" from activating in the middle of print jobs?

Please refer to the attached document for details on changing the settings of the printer from the factory defaults.  Three settings can cause problems while using the printer, especially for long print jobs.  One symptom is that the printer will stop in the middle of the print job because it goes into a sleep mode.
