Alert code list

• If an image stabilization or scanner fault occurs, the corresponding warning code
appears.

Item
• It is detected that the CCD clamp gain adjustment
value is faulty.
• While recovering from the power save mode or when
the main/sub power switch is ON, it detects whether or
not stain exist at the original glass moving unit when
the ADF is closed.
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] → [Thin line Detect. Set-
ting]
• While recovering from the power save mode or when
the main/sub power switch is ON, it detects whether or
not stain exist at the scanning guide when the ADF is
closed.
This warning will be displayed if the original is set to
ADF when stain exist.
• This setting is valid only when the [Detection during
Paper Passing] available from the following setting is
set to one between 2 and 6.
[Service Mode] → [System 2] → [Split Line Detect. Set-
ting]
• When adjusting the IDC sensor, output voltage
detected for all sample patterns are specified value or
more.
• When adjustment is complete, sensor's output voltage
with selected light intensity is specified value or under.
• 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).
• The number of points detected in the main scan direc-
tion is more or less than the specified value during
main scan direction registration correction.
• The number of points detected in the sub scan direction
is more or less than the specified value during sub scan
direction registration correction.
