these grooves to tilt the cover. When the printer cover is tilted up, you

cartridge between your thumb and index finger, slide it over the paper

ribbon cartridge and the ink ribbon. Ensure the ink cartridge is inserted
firmly to prevent weak or irregular printing. The cartridge must be
properly seated and aligned for the best printing.
Step 5. Turn the cartridge knob (marked by an arrow) clockwise to stretch the
ribbon taut.
Step 6. Replace the cover.

Step 8. Replace the paper if necessary.
If you get ribbon ink on the printer’s plastic cover, remove it immediately. Once dried, it is
difficult to remove.
