RIBBON REPLACEMENT/INSTALLATION

Note: The Ribbon Cartridge Refill (26-1489) has been discontinued.
      Order the Ribbon Cartridge (26-1296) for replacement ribbons.

If the ribbon cassette is already installed, simply check to see that it is
properly threaded between the paper and the print head.

If the ribbon cassette is not installed, or if it must be replaced due to
excessive wear, faint printing, etc., follow this procedure:

1. Set the Power switch to OFF.

NOTE: When you turn the power off, any information stored in the Printer's
      buffer will automatically be lost.)

2. Open the top cover and gently move the print head control lever toward
   the front of the Printer as far as it will go.

3. Gently move the print head toward the center of the Printer.

4. With your finger tips, pull out the plastic ribbon guide mounted on the
   nose of the print head.

5. Gently grasp the ribbon cassette at the corners nearest the paper
   (toward the rear of the printer) and remove the cassette by lifting it
   upward.

6. Unwrap the new cassette.

7. Securely insert the plastic ribbon guide, hooked on the ribbon, onto
   the nose of the print head.

8. Place the protruding pins of the cassette into the cutouts of the side
   frames; then gently press the cassette down until it is firmly secured
   by the stopper claws.

Note: Do not force the cassette into place!  If the cassette is not
      properly fitted, the cassette knob will not match up with the ribbon
       drive mechanism.  Do not force the cassette down, but fit it in
       gradually while turning the cassette knob in a clockwise direction.

9. Once the new cassette is installed, tighten the ribbon by rotating the
   knob located on the right side of the cartridge in a clockwise
   direction, as indicated by the arrow.

10. Move the carriage back and forth manually to check that the ribbon
    advances properly.

11. Move the print head control lever toward the rear side of the Printer.

12. Close the top cover.

REMEMBER! It is extremely important that the print head is as close to the
paper as possible; otherwise, damage to the print head may occur.  Simply
move the print head control lever toward the paper and move the carriage
back and forth until smudging occurs.  Then, gradually move the print head
away from the paper until smudging stops.
