Cover Assembly, Hammer Bank / Ribbon Mask

Removal
1. Prepare the printer for maintenance (page 132).
2. Remove the shuttle frame assembly (page 215).
3. Lift the thick plate of the hammer bank cover assembly at one end, and
peel the cover away from hammer bank magnets. (See Figure 23.)
Installation
CAUTION
The hammer bank contains a strong magnet. To prevent damage to the
hammer tips, do not let the steel hammer bank cover assembly of early
models snap into place as the hammer bank magnet attracts it. Any
impact of the cover against the hammer bank can break hammer tips.
1. With the thick plate facing the hammer bank, hold the hammer bank cover
assembly at a slight angle and engage the bottom edge on the alignment
pins. First engage the center (round) hole, then the left (oblong) hole, to
ensure that the cover lies flat on the hammer bank. (See Figure 23.)
2. Gently lower the hammer bank cover assembly until it lies flush on the
hammer bank.
3. Check that the hammer bank cover assembly is positioned over the
alignment pins and the hammer tips.
4. Install the shuttle frame assembly (page 215).
5. Return the printer to normal operation (page 133).
