DMP 107 (260-2821) Ribbon Replacement Faxback Doc. # 4508 Black Ribbon (26-1236) Color Ribbon Pak (26-1235) If the ribbon is already installed, simply check to see that it is properly threaded between the paper and 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. Set the power switch to OFF. NOTE: When you turn off the power, any information stored in the printer's buffer is automatically lost. 2. Open the printer cover. If necessary, remove the cover by setting it in an upright position and lifting it upward. 3. Remove the old ribbon cassette by grasping the fin on the cassette 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. While rotating the ribbon feed knob in the direction indicated by the arrow, press down the right side of the cassette. If the ribbon feed knob does not match up with the ribbon drive mechanism, the cassette will 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 cassette knob in the indicated direction. 7. Replace the printer cover. If you have removed the cover, hold it up- right and insert its edge into the grooves on the printer. Then lay it down. CAUTION: Printing without paper or ribbon can damage the print head or platen. (dtc-07/26/93)
