The location will be retained evenwhen the printer is turned off or unplugged until you reset it.If no paper is inserted, pressing the SHIFT+ TOF button sets the top ofform position to 0.85 inch from the top of the page, the default setting forthe Cut-Sheet Feeder.Page MarginsFor best results we recommend that you maintain minimum page marginsas shown in the diagram below.
