appears.

P-9 Drum/Development unit (K) failure
P-14 Skew correction trouble
P-21 Color regist test pattern failure

Item
• It is detected that the CCD clamp gain adjustment
value is faulty.
• When the main/sub power switches are turned ON or
when the machine is recovering from the power save
mode, if the original cover is not open, the cleaning
brush rotates 360 degrees to detect whether or not
stain exists in the original reading section.
This warning will be displayed if the original is set to
ADF when stain exist.
• The thin line detection level and the warning display
can be changed by the following setting.
[Service Mode] → [System 2] → [Split Line Detect. Set-
ting]
• During IDC sensor light intensity correction, output volt-
age detected for all eight sample patterns are 3.25 V or
more.
• During IDC sensor light intensity correction, sensor out-
put voltage for light intensity selected after the correc-
tion is under 0.7 V.
• During IDC base surface detective control, sensor out-
put voltage detected is under 0.7 V or over 3.25V.
• During image stabilization (gamma correction control),
detected output value for IDC sensor did not go below
threshold (half the value of what is detected by IDC
sensor on the belt surface) for three consecutive times
(position of the pattern end is not detected).
• During image stabilization (gamma correction control),
sensor's output value of each color for hyper 0 grada-
tion after the primary approximation is half the detec-
tion level on the belt surface or under.
• All density readings taken from the density pattern pro-
duced on the transfer belt are 1.0 g/m
photo receiver output) or less during max. density
adjustment (Vg/Vdc adjustment).
• All density readings taken from the density pattern pro-
duced on the transfer belt are 5.0 g/m
photo receiver output) and more during max. density
adjustment (Vg/Vdc adjustment).
• The difference between the skew default position set-
ting value and the cumulative amount of skew adjust-
ment values goes over the predetermined value.
• During pre-pattern detection, pre-pattern edge (start/
end point of effective area) is not detected within the
pre-pattern search area.
• During detection of regist pattern at vertical/horizontal
direction, pattern edge (start/end point of effective
area) is not detected within the pattern search area of
each unit.
