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.

Description
Data sampling was correctly done and line position
adjustment was successfully completed.
The calculated result for line position correction is
greater than ±2.0 mm.
Distance between the lines is greater than ±1.4 mm.
Data sampling cannot be done correctly.
The ascending or descending slope of the ID sensor
signal wave is out of specification.
The detected number of pattern lines is less than 64
lines.
Data sampling cannot be done within the allocated
time.
The start mark cannot be detected within the
allocated time.
The pattern length is shorter or longer than specified.
The detected number of pattern lines is over 64
lines.
The calculated magnification value does not match
any data in the laser power frequency adjustment
data table.
The machine is in the toner near-end or toner end
condition.
The machine is not ready to do the line position
adjustment manually from the user menu.
Line position adjustment cannot be done due to
failed potential control.
The necessary mirror angle correction is outside the
adjustment range (cyan only).
The detected magnification value is out of the
adjustment range (yellow only).
The detected sub scan registration is out of the
adjustment range (yellow only).
The detected main scan registration is out of the
adjustment range (yellow only).
