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
Code: SC192
Description: Bar code number mismatch Type: 2 - Description - The SCU compares the bar code data read by the CCD and analyzed by the scanner IPU board with the machine identification number stored in the machine. If they do not match, the SCU determines that there is a bar code number mismatch. - Detection Timing - When the power switch is turned on
Causes: • SCU (System Control Unit) SP-Log: 7-402-1
Code: SC193
Description: IDU failure Type: 2 - Description - The IDU board diagnostics notify the scanner IPU board that it is faulty at power-on. Then the scanner IPU board notifies the SCU of this. - Detection Timing - When the power switch is turned on
Causes: • IDU SP-Log: 7-402-1
Code: SC196
Description: Extended IPU abnormal Type: 4 - Description - The extended IPU board diagnostics notify the scanner IPU board when its image processing ASIC on the extended IPU board is faulty at power-on. Then the scanner IPU board notifies the SCU of this. This check is not made if the extended IPU board is not installed. - Detection Timing - When the power switch is turned on
Causes: • Extended IPU SP-Log: 7-402-1
Code: SC197
Description: Extended IPU connection abnormal (A189 machine only) Type: 4 - Description - The SCU detects when the extended IPU is not connected. - Detection Timing - When the power switch is turned on
