CIS transmission error

The data read from the ASIC register on the CIS were not as expected.

Details:

 Occurs when a serial communication error between the CIS board and the DF board is detected. Occurs also when an error is detected during initialization of the ASIC on the CIS.

 This can happen during initialization and feeding. The first and second consecutive occurrences of each constitute jams. The third occurrence constitutes an SC.

(An initialization jam/transport jam occurs on 2 continuous occasions during either initialization or transport, and on the 3rd continuous occasion, an SC is generated)

 Connector or harness between DF board and CIS board is disconnected or defective

 ASIC on the CIS is defective

 Boot failure of ASIC on the CIS

CIS LED error

During initialization:

 The ratio between the average values of leading-edge area and rear-edge area is out of specification.

 Shading data peak value is below specification. 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.

(An initialization jam/transport jam occurs on 2 continuous occasions during either initialization or transport, and on the 3rd continuous occasion, an SC is generated)

During initialization:

 One or two out of two CIS LEDs are defective During scanning:

 Both of the CIS LEDs are defective.
