4.1.3 LINE POSITION ADJUSTMENT RESULT
SP5-993-007 (Line Position Adjustment Result)
This SP shows the six digits number as a line position adjustment result on the
LCD. It shows which parts of the transfer belt has an error (front, center or rear).
• The first and second digits from left-hand indicate the result detected by the front
ID sensor.
• The third and fourth digits indicate the result detected by the canter ID sensor.
• The fifth and sixth digits indicate the result detected by the rear ID sensor.
No. Result Description Note
01
Successfully
completed
