5、g adjustment procedures are not only necessaryafter replacement of consumable mechanical parts or boardassemblies, but are also provided as references to be referredto when servicing the electrical circuitry. In case of trouble with the electrical circuitry, always begin aservice by identifying the

6、defective points by using the measur-ing instruments as described in the following electrical adjust-ment procedures. After this, proceed to the repair,replacement and/or adjustment. If the required measuring in-struments are not available in the field, do not change the ad-justment parts (variable
