DMP-135 (260-2866) Ribbon Faxback Doc. # 4329 Ribbon Cassette 260-1236A INSTALLING THE RIBBON CASSETTE If you have already installed the sample ribbon cassette included with your printer, be sure that you correctly threaded the ribbon between the ribbon mask and the print head. If you have not yet installed the ribbon cassette or if you need to replace an old ribbon, follow this procedure. 1. Turn off the printer. NOTE: When you turn off the printer, it loses any information stored in the buffer. 2. Place the paper rack in its horizontal position, slide it toward the back of the printer, and open the printer cover. If you need to remove the cover, raise the cover to about a 45-degree angle and then lift it upward. 3. Remove the old ribbon cassette by grasping the handle on top of the cassette. Then, gently pull it upward. 4. Unwrap the new ribbon cassette (Cat. No. 260-1236A) and tighten the ribbon by turning the ribbon feed knob in the direction shown by the arrow. 5. Look at the bottom of the cassette. There is a hole on the underside of the ribbon feed knob. Position the left end of the cassette so that the ribbon feed spindle slides into this hole. Then, carefully 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 shown by the arrow. Pull the right side of the cassette against the inside panel so that the cassette is straight. Then, press down on the right side of the cassette until you hear a click. If the ribbon feed knob does not match up with the ribbon feed spindle, the cassette does not fit precisely. Do not force the cassette into place. Instead, remove the ribbon cassette and try again. 6. Once you have installed the new cassette, tighten the ribbon by turning the ribbon feed knob in the direction shown by the arrow. 7. If you removed the printer cover, replace it by holding it at about a 45-degree angle. Slide the grooves in the printer cover over the tabs on the printer. Then, lower the printer cover to its closed position. 8. Slide the paper rack forward to lock the printer cover. CAUTION: Printing without ribbon or paper can damage the print head or the platen.
