5.2.7 PG Offset Value Adjustment
 Overview
To compensate the deviation of the PG position (see Table 5-7 (p229)) derived from
the difference of the result of PG Adjustment/PG Inspection (p.229) due to individual
variability of the mechanism, write the notch positions of the parallelism adjustment
bushings when
PG Adjustment/PG Inspection (p.229) is performed into EEPROM to
correct the PG position during APG operation.
 Preparation
After PG Adjustment/PG Inspection (p.229) is complete, check the notch position of
the parallelism adjustment bushing at the rear on the 0-column side and note down the
offset value according to the figure below.

engaged on the rib on the frame.
