[5] ADJUSTMENTS AND SETTINGS
1. General
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. Per-
form only the necessary adjustments according to the need.
Unnecessary adjustments can be omitted. Even in this case, how-
ever, 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.
