[7] SETTING AND ADJUSTMENTS
1. Adjustment/setup items list
Each adjustment item in the adjustment item list is indicated with its JOB number. Perform the adjustment procedures in the sequence of Job num-
bers from the smallest to the greatest.
However, there is no need to perform all the adjustment items. Perform only the necessary adjustments according to the need. Unnecessary adjust-
ments can be omitted. Even in this case, however, the sequence from the smallest to the greatest JOB number must be observed. If the above pre-
caution should be neglected, the adjustment would not complete normally or a trouble may occur.
