paper and push the blue lock lever to lock the sprocket in place.
Then slide the right sprocket to match the width of your paper, but
do not lock it. Move the paper supports midway between the two
sprockets.

sprocket covers. Fit the first holes of the paper over the sprocket pins
and then close the sprocket covers. Slide the right sprocket to
remove any slack in the paper and then lock it in place.
Note:
Remove any remaining slack by gently pulling the paper from the back.

paper guide. Hold it horizontally and fit its notches over the
printer's mounting posts. Then slide the paper guide toward the
back of the printer until you feel it click.
11. Turn the paper feed knob to adjust the paper position. The
perforation between pages should be just above the print head.
