Description: Scanner ROM mismatch - Timing - After software installation or just after the main switch is turned on - Condition - The scanner IPU board detects that the software installed is not the correct one.
Causes: • An invalid IC card used (such as a card for a different model) • Replace the scanner IPU board.
Remedy: Try again with the correct IC card. Replace the scanner IPU board.
Code: SC170
Description: Video processing error 1 - Timing - Just after the main switch is turned on (after auto gain control on the scanner IPU board) - Condition - The corrected CCD odd/even pixel black level difference is not in the proper range.
Remedy: 1. Check if the flat cable is firmly connected at CN421 and CN404 on the SBU and scanner IPU board. 2. Check the continuity of the flat cable. 3. Replace the scanner IPU board. 4. Replace the SBU unit.
Code: SC171
Description: Video processing error 2 - Timing - Same as SC170 - Condition - The corrected black level is not in the proper range.
Remedy: 1. Check if the flat cable is firmly connected at CN421 and CN404 on the SBU and scanner IPU board. 2. Check the continuity of the flat cable. 3. Replace the scanner IPU board. 4. Replace the SBU unit.
Code: SC172
Description: Video processing error 3 - Timing - Same as SC170 - Condition - The corrected white level is not in the proper range.
Remedy: 1. Check SP 4-426-001 to 006 (RGB Gain). If their values are near “255”, clean the optics section (exposure glass, white plate, mirrors, and lens). 2. Visually check if the exposure lamp turns on during warming-up after the main switch is turned on. If not, replace the lamp regulator. 3. Check if the CCD flat cable is firmly connected at CN421 and CN404 on the SBU and scanner IPU board. 4. Check the continuity of the flat cable. 5. Replace the scanner IPU board. 6. Replace the SBU unit.
Code: SC191
Description: Bar code scan error - Timing - Just after the main switch is turned on - Condition - The scanner IPU board detects that the bar code pattern scanned in is not appropriate.
Causes: • Non-standard bar code label • Improper location of bar code • Dirty bar code • Defective scanner IPU board • Defective main control board
Remedy: 1. Check if the bar code is damaged or scratched. 2. Clean the optics section components, such as mirrors and lenses, and the bar code label. 3. Check if the mirrors are properly positioned on the 1st and 2nd scanners. If the spring plate which secures the mirrors is out of position, it causes the light axis to be changed. 4. Replace the scanner IPU board. 5. Replace the main control board.
Code: SC192
Description: Bar code number mismatch - Timing - Just after the main switch is turned on - Condition - The main control board detects that the bar code data scanned in does not match the machine identification number stored in the RAM.
Causes: • Defective RAM board • Defective scanner IPU board • Defective main control board
Remedy: 1. Check if the serial number stored in the RAM is correct. NOTE:. Contact your product specialist for the detailed procedure. 2. Check the copier's serial number and the number defined in SP mode. 3. Garbled ROM data: Replace the NV-RAM. 4. Replace the scanner IPU board. 5. Replace the main control board.
