4. All Adjustment

This mode is used to adjust all image
reading adjustments at the same time. Since
the adjustment value is saved on the control
PCB, be sure to execute this mode after the
control PCB have been replaced.
This mode consists of two individual ad-
justment items: "Regist Adjustment" and
"Document Sensor Adjustment."
• Operating Procedure
1) Clean the document board sensor window,
the shading plate and the reading glass.
2) Set a piece of regular white copy paper
(A4/LTR). The paper can be set both ver-
tically and horizontally. Set the document
guide position to the paper. This paper is
used to perform "Regist Adjustment."
3) Select [All Adjustment] on the service
screen.
