selected:
If the rear tractor arrow light is red, press the LF/FF Load
button to load the paper.
If the front tractor arrow light is red, press the Front/Rear
button to switch to the rear tractor. When the printer switches
tractors, it also loads the paper automatically.
The Tractor Select indicator changes to green. The paper is now
loaded to the top-of-form position. If it looks like the printing will
start too high or low on the page, adjust the paper position. See
“Adjusting the Paper Position” on page 29 for instructions.
