Chapter 5 Section I: Replacement Procedures

Installation

1. Using a clean dry cloth, wipe the hammer spring mounting surface on the

hammer bank. Make sure the cloth does not leave lint on the hammer

bank.

CAUTION

Hammer springs and hammer tips are fragile. Do not touch the hammer

springs or tips. Handle hammer springs by the thick mounting base

only. Apply pressure only to the mounting base.

2. Handling the hammer spring assembly by the mounting base only,

remove the new assembly and mounting screws from the box.

3. Handling the hammer spring assembly by the mounting base only,

carefully position the new assembly onto the hammer bank mounting pins

and press it into position with the stick supplied in the hammer spring

replacement kit. (See Figure 23, page 169.)

4. Install the mounting screws from the replacement kit. Using a Torx T-10

bit adapter, torque each screw to 14 in-lbs (1.58 N•m). Tighten the center

screw(s) first. (See Figure 23, page 169.)

5. Install the hammer bank cover assembly (page 157).

6. Install the shuttle frame assembly (page 198).

7. Install the ribbon and load paper.

CAUTION

Do not attempt to adjust or “tweak” hammer springs.

8. Run a Diagnostic Printer Test and check print quality (page 89):

a. If print quality is acceptable, return the printer to normal operation

(page 107).

b. If print quality is still degraded, replace the shuttle frame assembly

(page 198).
