The ADF must be adjusted for the following items and in the following sequence of work:
1. If you have replaced major parts of the ADF, you must always execute
the following: registration arch auto adjustment, original read position
adjustment. Then, check to make sure that the settings of other items of
adjustment are as indicated; if not, make adjustments starting with the
preceding item of adjustment.
2. Each item of adjustment affects the subsequent items of adjustment. If
you have made adjustments, therefore, be sure to check that the setting
of the item of adjustment that follows is also as indicated; if not, be sure
to start over with the preceding item.
