Section 6. Replacement Procedures

6.2 Replacing the Main Circuit Board

The Main Circuit Board contains the control electronics for the printers and is located behind L.H. cover of the printer. The I/O PCB interface and optional memory card unit if installed, which are attached to the main circuit board must first be removed.

NOTE: Many of the components on this board are susceptible to damage by static electricity. To avoid damage from static electricity, do not unpack new circuit boards from anti-static bags until instructed to do so and use a wrist grounding strap.

For each spindle, position and fasten Item 11 Plate, with teeth facing outward with (2) screws. Except for Item 9, all items are the same for the ribbon unwind and ribbon rewind assemblies, List 6-A and Figs.

6-41 through 6-44.

Install Item 10 Felt Friction Washer onto the Ribbon Shaft and slide it against Item 11 Plate. The jagged teeth on Item 11 Plate will "dig into" the felt washers. Slide (1) Item 9a or 9b Wind or Unwind Disc Plates onto each Ribbon Shaft. The teeth/slots on the unwind disc plate must be face towards felt washer. Fig. 6-45 & 6-46

Slide (2) Item 7 Collars onto the Ribbon Shaft and against Item 9a or

9b Wind or Unwind Disc Plates.

NOTE: The collars may still be inside the ribbon boss.

List 6-A and Fig. 6-43

Slide Item 8 Ribbon Bosses onto the Ribbon Shaft. Align the pegs on

Item 8 with the location holes on the Item 9a/9b disc plates. Slide the

3rd Item 7 Collar onto the shaft and into Item 8 Ribbon Boss. List 6-A,

Fig. 6-43 and Fig. 6-47

Install Item 6 Oil-less Dry Metal Washer onto the ribbon shaft with the frictionless coated side facing outward away from Item 8. Align the hole on Item 6 Washer with the peg on Item 8 Ribbon Boss.

List 6-A,

Fig. 6-43 and Fig. 6-48

Install Item 5 Disc onto the ribbon shaft with the smooth side facing

Item 6 Washer, (one side of the disc is smooth and the other side has rough edges). List 6-A and Fig. 6-42

Place Item 4 Spring next on the shaft, then Item 3 Stopper Collar.

List 6-A and Fig. 6-42

Screw Item 2 Adjustment Nut clockwise into the end of the ribbon shaft until it just touches the stopper collar. Fig. 6-41 & 6-42

NOTE: Do not over-tighten the adjustment nut since this screw is used to adjust the clutch tension. Adjust the clutch tension as outlined in

Section 5-2

Install Locking screw. Hold Adjust nut with 12mm wrench while tightening screw to avoid changing clutch adjustment.

Reconnect the power cable.
