3.Move the left edge guide so that it locks in place next to the guide mark.
4.Adjust the right edge guide to match the width of your paper. Next, slide a sheet down between the edge guides until it meets resistance.
WARNING: Run the self test using paper wider than A4 (81/4 inches or 210 mm) or letter size (BY2 inches or 216 mm), to prevent the print head from printing directly onto the platen.
