4. Cut a straight edge on the paper roll if it is jag-
ged. This will facilitate the entry of the paper into
the printer.
5. Slide the paper through the slot connecting the
paper compartment and the printer compart-
ment. You can slide it in about one-quarter inch
before it stops.
6. While holding the paper in place, press the
rocker switch to the Paper Feed position. The
printer will activate, and a rubber roller will pull
the paper into the printer compartment. Hold the
switch in the Paper Feed position until the paper
emerges from the top of the printer mechanism.
7. When an inch of paper has emerged from the
top of he printer, release the Paper Feed button.
8. Now pull the paper through the printer, until
several inches are exposed.
9. Slide the paper through the slot in the printer
cover.

place.
11. Press the front of the printer cover down to lock
in place.
12. Put the paper spindle into the paper roll as
shown below, and place the roll with the spindle
onto the snaps near the back of the printer. Turn
the paper roll to take up any slack in the paper
feeding to the printer. Make sure the roll of paper
turns freely. If it does not turn freely, the paper
will jam and will possibly damage the printer
mechanism.

To Remove the
Paper Roll
1. Advance the paper about one inch beyond the
paper cutter by using the Paper Feed switch.
2. Lift the paper roll away from the printer hous-
ing and cut the paper feeding to the printer with
scissors. Try to make the cut as square as pos-
sible to help the next time you reload the paper.
3. Pull the remaining paper through the printer
mechanism. Be sure to pull the paper from
the top (paper cutter side).
WARNING! Pulling the paper out of the back of
the printer will damage the print mechanism
