Description: Lamp failure (broken or persistently on) Type: 3 - Description - When the lamp regulator detects that the exposure lamp is not turned on or is not turned off, the scanner IPU informs the SCU of this. - Detection Timing - Failure to go on (break) is detected when the lamp is turned on. Failure to go off (persistently on) is detected when the lamp is turned off.
Causes: • Lamp regulator defective • Exposure lamp open • Optics thermoswitch open SP-Log: 7-402-1
Code: SC120
Description: Scanner HP sensor abnormal - Stays off Type: 3 - Description - The scanner IPU board notifies the SCU when the home position sensor does not go on even though the scanner carriage has been returned to the home position during the scanner carriage homing process of the power-on sequence. - Detection Timing - When the power switch is turned on and the scanner homing operation starts
Causes: • Scanner HP sensor defective SP-Log: 7-402-1
Code: SC121
Description: Scanner HP sensor abnormal - Stays on Type: 3 - Description - The scanner IPU board notifies the SCU when the home sensor does not go on even though the scanner carriage has been retracted from the home position during the scanner carriage homing process of the power-on sequence. - Detection Timing - When the power switch is turned on and the scanner homing operation starts
Causes: • Scanner HP sensor defective • Scanner motor defective SP-Log: 7-402-1
Code: SC130
Description: Scanner start abnormal Type: 3 - Description - The scanner IPU board notifies the SCU when the next scan start signal is received before the scanner carriage has returned to the home position. - Detection Timing - During scanning
Causes: • Scanner IPU board SP-Log: 7-402-1
Code: SC170
Description: VPU abnormal 1 Type: 3 - Description - The scanner IPU board notifies the SCU when the feedback data for the black level (mask area at the front end of the CCD) E/O is not in the proper range at power-on. - Detection Timing - When the power switch is turned on
Causes: • Scanner IPU board SP-Log: 7-402-1
Code: SC171
Description: VPU abnormal 2 Type: 3 - Description - The scanner IPU board notifies the SCU when feedback data for the white level is not in the proper range at power-on. - Detection Timing - When the power switch is turned on
