Hammer Spring Retensioning (Figure 5–3)
NOTE: Tensioning hammer springs is a trial–and–error process. Adjust and
test until print quality is satisfactory.
If Print is Too Light:
1. Put the hammer bank in the service position. (See page 5–2.)
CAUTION
The hammer tip is fragile. Take care not to damage the hammer tip with
the screwdriver when flexing the spring.
2. Using the tip of a screwdriver, carefully flex the tip of the hammer spring
away from the pole pin under the spring.
3. Return the hammer bank to the operating position. (See page 5–6.)
If Print is Too Dark:
1. Put the hammer bank in the service position and remove the hammer
spring. (See page 5–2.)
CAUTION
The hammer tip is fragile. Be careful not to damage the hammer tip with
the screwdriver when flexing the spring.
2. Grip the spring with long nose pliers so the screw hole is just covered.
Using the tip of the screwdriver, carefully flex the spring in a direction
away from the hammer tip.
3. Install the hammer spring. (See page 5–2.)
4. Align the hammer tip. (See page 5–10.)
