AR-M550/M620/M700 SETTING AND ADJUSTMENTS 7 - 1
[7] SETTING AND ADJUSTMENTS
Each adjustment item in the adjustment item list is associated with a specific JOB number. Perform the adjustment procedures in the sequence of Job
numbers 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 adjustments can be omitted. Even in this case, however, the sequence from the smallest to the greatest JOB number must be observed.
If the above precaution should be neglected, the adjustment would not complete normally or trouble may occur.
