5.2.18 Ribbon Supply Spindle and Clutch Replacements

Figure 5-30 shows the Ribbon Supply Spindle and associated Clutch Assembly. Replacement options include any of the parts that appear in the exploded view.

Step 1. Remove the Rear Case (see Section 5.2.1) the Front Case (see Section 5.2.2) and the Rear Plate (see Section 5.2.11).

Step 2. Remove the Flag and Head Latch Sensor Board (see Section 5.2.13).

Step 3. Remove the screw and captive washer holding the Supply Spindle, and slide the spindle off of the rod.

Step 4. Slide the clutch and flag assembly toward the rear until free of the printer.

Note: At this point, reassembly can occur with a new Clutch and Flag Assembly, a new Spindle, or both. Also, with further disassembly, individual Clutch parts can be replaced (note the items in the exploded view). However, any new Clutch Pads require a burn-in followed by a torque test. Normally two washers are used on the side closest to the Rear Plate to create the proper torque. Added washers increase torque while washer removal decreases torque. A torque of from 185 to 250 centimeter grams produces the required clutch friction.
