During scanning:
• 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.
During initialization:
• One or two out of two CIS LEDs are defective
During scanning:
• Both of the CIS LEDs are defective.
• Reconnect the power/signal harness.
