PRINTER

Why won't my printer print?
Your paper may be installed wrong. See next question below for the answer.

How do I change the paper roll properly?
(1) Remove the paper cover by pushing it toward the rear of the unit and lifting up. Be sure to remove and save the paper roll spindle that is inside the paper roll you are removing: you'll need it later.
(2) Cut or tear the paper to separate the paper roll from the paper in the machine.
(3) To remove the paper remaining in the printer, press the [RETURN] key several times until the paper comes out at the top of the printer.
(4) Cut the paper at the end of the new roll into a point or "V" shape: Place the paper roll spindle that you removed in step 1 into the hole in the center of the paper roll.
(5) Insert the new paper roll by feeding the paper into the well. Be sure that paper feeds from the BOTTOM of the roll.
(6) Using the [RETURN] key, feed the paper until it comes up behind the print head. Continue feeding until the paper comes up through the paper cutting window.
(7) Place the roll of paper in the paper well and replace the plastic cover on the machine.
