ƒ Keep NVRAMs away from any objects that can cause static electricity. Static
electricity can damage NVRAM data.
ƒ Make sure the NVRAM is correctly installed on the controller board.
ƒ Make sure that the DIP-switch settings on the old controller board are the same for the new controller board. Do not change the DIP switches on the controller board
in the field.

SM 4-7 B230/B237/D042 Trouble shooting 4.2 SCANNER TEST MODE 4.2.1 VPU TEST MODE Output the VPU test pattern with SP4-907- 001 to make sure the scanner VPU control operates correctly. The VPU test pattern prints out after you have set the SP mode settings and pressed the start key. ƒ The CCD on the SBU board may be defective if the copy is abnormal and the VPU test pattern is normal. ƒ The following can be the caus e if the copy is normal and the VPU test pattern is abnormal: ƒ The harness may not be correctly c onnected between the SBU and the BICU ƒ The BICU (IPU) or SBU board may be defective. 4.2.2 BICU (IPU) TEST MODE You can check the BICU (IPU) board with the SP mode menu, SP4-904-1 or -2. If no error is detected, the test ends. Then the completion code shows in the operation panel display. If an error is detected, the test is interrupted. Then an error code shows. The table below lists the completion and error codes. SP4-904-1 Register Access There are 16 bit switches in this SP. Each bit indicates each CPU as follows. The error result is displayed on the oper ation panel in decimal number. 0: Normal, 1: Error Bit 0: TAURUS register Bit 1: ORION register Bit 2: LUPUS register Bit 3 to 11: Not used Bit 12: Ri20 register Bit 13 to 15: Not used SP4-904-2 Image Path There are 16 bits switches in this SP. Each bit indicates each CPU path as follows. The error result is displayed on the operation panel in decimal number. 0: Normal, 1: Error Bit 0: Image path from SBU to TAURUS Bit 1: Image path from TAURUS to ORION Bit 2: Image path from ORION to TAURUS Bit 3: Image path from TAURUS to LUPUS Bit 4 to 11: Not used Bit 12: Image path from LUPUS to Ri20 Bit 13: Image path from Ri20 to GAVD Bit 14 and 15: Not used
B230/B237/D042 4-8 SM Errors may be caused by the following problems: 1. Short circuit on the signal lines ƒ When the BICU board is installed, a pin or two on the ASIC is damaged. ƒ Some conductive matter or obje ct is trapped among the pins. ƒ Condensation 2. Destruction of circuit elements ƒ Over current or a defective element breaks the circuit. 3. Abnormal power supply •The required voltage is not supplied to the devices. 4. Overheat/overcooling ƒ The environment is inappropriat e for the board (the scanner unit). 5. Static electricity ƒ Static electricity of a high voltage occurs during the test. 6. Others ƒ The scanner and BICU are incorrectly connected. When you have completed a check, turn the main switch off and on before you do another check. When you have completed all necessary checks, turn the main switch off and on.
