INSTALLING THE RIBBON CASSETTE

If the ribbon (260-1236A) is already installed, check to see that it is
properly threaded between the paper and the print head.

If the ribbon cassette is not installed or needs to be replaced, follow 
this procedure:

1. Set the printer power switch to OFF/0.

NOTE: When you turn the printer power off, any information stored in the
printer's buffer is lost.

2. Lay down the paper rack, slider it towards the back of the printer and 
   open the printer cover. If necessary, to remove the cover, set it in an
   upright position and lift it upward.

3. Remove the old ribbon cassette by grasping its fin and gently pulling it    
   upward.

4. Unwrap the new cassette and tighten the ribbon by turning the ribbon 
   feed knob in the direction indicated by the arrow.

5. Gently thread the ribbon between the ribbon mask and the print head. 
   Press down on the left side of the cassette until you hear a click. 
   Turn the ribbon feed knob in the direction indicated by the arrow, and 
   press down the right side of the cassette.

If the ribbon feed knob does not match up with the ribbon drive mechanism,
the cassette does not fall into place. Do not force the cassette into 
place.  Instead, fit it into place gradually while turning the ribbon feed
knob.

6. Once the new cassette is installed, tighten the ribbon by turning the       
   ribbon feed knob in the indicated direction.

7. Replace the printer cover by holding it upright and inserting its edge 
   into the grooves on the printer. Lay it down and replace the paper 
   rack to its original position.

CAUTION: Printing without paper or ribbon can damage the print head or 
platen.
