• Code: SC101
• 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- The scanner IPU board notifies the SCU when the home sensor does not go on even though the scanner carriage has been retracted from the home position during the scanner carriage homing process of the power-on sequence.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
• Causes: • Scanner IPU board SP-Log: 7-402-1

• Code: SC172
• Description: VPU abnormal 3 Type: 3 - Description - The scanner IPU board notifies the SCU when the white shading data is not in the proper range after the white level has been adjusted (SP4-435). - Detection Timing - When the above SP mode is performed
• Causes: • Scanner IPU board SP-Log: 7-402-1

• Code: SC191
• Description: Bar code scanning error Type: 2 - Description - The bar code on the scanner guide plate is scanned by the CCD and stored in the SCSI buffer memory. The scanner IPU board reads the data and performs a pattern analysis on the data. If the scanner IPU board determines that the image pattern is not an appropriate bar code pattern, it notifies the SCU of a bar code scanning error. - Detection Timing - When the power switch is turned on
• Causes: • Non-standard bar code label SP-Log: 7-402-1
