Using Continuous Paper
11. Turn on the printer. It will beep because there is no paper in the
printer. Then press the LOAD/EJECT button to feed paper to the
loading position.
12. Press the ON LINE button to set the printer on line so that it can
accept data.
The printer remembers the loading position and advances each page
to the same position. If you need to adjust the loading position, use
the micro-adjustment feature. See the section on setting the loading
position in Chapter 3.
CAUTION: Never adjust the loading position using the
platen knob and never turn the platen knob while the
printer is turned on.
