Figure 11. Positioning the Left Tractor to Avoid Damage
CAUTION To avoid damage to the printer caused by printing on the platen, always
position the left tractor unit directly to the left of the “1” mark on the
paper scale.
21. Normally, you should not need to adjust the position of the left tractor.
If adjustment is necessary, unlock the left tractor by placing the tractor
lock in the middle position. Slide the tractor until it is directly to the left of
the number “1” on the paper scale and lock it. (You can also use the
paper scale to count columns.)
