• Shading data peak value is below specification.

Details:

During initialization:

• Occurs when one out of two CIS LEDs is malfunctioning, causing the difference between the average values of leading-edge area and rear-edge area to be large (CIS LED error detection).

• Occurs when both of the CIS LEDs are malfunctioning (unlit), causing the shading data peak value to be extremely low (CIS white level adjustment).

During scanning:

• Occurs when both of the CIS LEDs are malfunctioning (unlit), causing the shading data peak value to be extremely low (CIS scan control, gray balance adjustment/confirmation).

• The first and second consecutive occurrences of each constitute initial/feed jams. The third occurrence constitutes an SC.

• One or two out of two CIS LEDs are defective

During scanning:

D

CIS white level error

• The shading data peak value read out from the CIS is abnormal.
