Installing the Ribbon Cassette:

Follow these steps to install the standard black ribbon cassette.

CAUTION:

* Printing without a ribbon damages the print head and the platen.
* Before you replace the ribbon cassette, set POWER to OFF and unplug the
  printer.
* When you turn off the printer, it loses any information stored in the
  buffer. (The buffer holds information the computer has sent but the
  printer has not printed.)

1. Open the printer cover.

You might find installing a ribbon easier if you completely remove the
printer cover. To remove the cover, raise it to a 45-degree angle and pull
it away from the printer.

2. Remove the ribbon cassette from its protective bag. Tighten the ribbon
   by turning the ribbon feed knob in the direction shown by the arrow.

3. Slide the print head to the center of the paper bail. Then carefully
   thread the ribbon between the ribbon mask and the print head.

4. Position the left end of the cassette so the black ribbon feed spindle
   (the lower one, in black) slides into the hole on the underside of the
   ribbon feed knob.

5. Press down on the left side of the cassette until the cassette is
   straight.  Then press down on the right side of the cassette until it
   snaps into place.

6. Pull the right side of the cassette back until the cassette is straight.
   Then press down on the right side of the cassette until it snaps into
   place.

CAUTION: If the ribbon feed knob does not line up with the ribbon feed
spindle, the cassette is not properly inserted. Do not force the cassette
into place. Instead, remove the cassette and try again.

7. Tighten the ribbon by turning the ribbon feed knob in the direction show
by the arrow.
8. If you removed the printer cover, replace it by holding it at a 45
   -degree angle and sliding its grooves over the printer's tabs. Close the
   printer cover.

When the print becomes light, replace the ribbon cassette with a standard
black ribbon cassette (26-2871). To remove the old ribbon cassette, grasp
the handle on the top of the cassette. Then gently pull it up.

Installing the Optional Color Ribbon Cassette:

   exposed ribbon. Position the color ribbon cassette as shown, and put the
   ribbon roller guide over the print head.

   print head and ribbon mask.

8. Fit the pins on both ends of the cassette into the corresponding notches
   in the printer. Push the cassette down until it clicks into place.

10. If you removed the printer cover, replace it by holding it at a
    45-degree angle and sliding its grooves over the printer's tabs. Close
    the printer cover and replace the paper rack.

Note: When the print becomes light, replace the ribbon cassette with an
optional Color Ribbon Cassette (26-2900). Follow these guidelines when you
replace the ribbon cassette.

* Before you replace the ribbon cassette, set POWER to OFF and unplug the
  printer.

Note: When you turn off the printer, it loses any information stored in the
buffer.

* To remove the old color ribbon cassette, lift its left side to avoid
  damaging the ribbon cassette holder.

Adjusting the Color Ribbon Position:

If you notice a color misalignment after you run the color self test,
rotate the adjustment shaft.

* If the upper part of the black line of the self test has cyan, the ribbon
  cassette is too low: rotate the adjustment shaft toward the back of the
  printer.

* If the black line lacks the bottom part, the ribbon cassette position is
  too high: rotate the shaft toward the front of the printer.
