DMP 302 (26-2849)   Installing/Replacing the Ribbon    Faxback Doc. # 4174


Ribbon Cassette (26-2819)

Follow these steps to install the ribbon cassette:

If the ribbon 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 you need to replace it due 
to excessive wear or faint printing, follow this procedure:

1. Turn off the POWER switch.

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

2. Open the access cover.
3. Position the print head between the bail rollers. Be sure that paper bail
   is closed.

WARNING: The print head can get very hot during extended periods of printing.
Be sure to let the print head cool off before you touch it.

4. Remove the old ribbon cassette by grasping it at the arrow marks and 
   gently pulling it upward.
5. Unwrap the new cassette. Before inserting the new cassette, tighten the
   ribbon by turning the ribbon feed knob in the direction indicated by the
   arrow.
6. Hold the ribbon cassette with the ribbon feed knob facing up and the 
   flat end toward the front of the printer.
7. Place the flat end into the ribbon plate. Then, lower the front of the
   cassette over the print head until it snaps into place.
8. Turn the ribbon feed knob in the direction of the arrow to take up the
   slack in the ribbon.
9. Replace the access cover.

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