I Have looked for this manual for quiet a while now, I have finally found it here. I believe this is the only place they have them in a very nice scan, pages are very clear to read, some of the pages are a bit tilted but overall it is great to have this manual available for purchase. Thanks

IMAGE PROCESSING
17 May, 1999
White Level Correction
Before scanning the original, the machine reads a reference waveform from the white plate. The average of the white video level for each pixel is stored as the white shading data in the FIFO memory in the IPU chip. The video signal information for each pixel obtained during image scanning is corrected by the IPU chip. Auto shading for the first original is done before the scanning. After scanning every page, auto shading is done to prepare for the next page. If the copy image density or the original mode is changed during copy run, the auto shading for the next scan is done before the scanning to respond to the mode changed.
White Line Erase Compensation
During the white level correction, if extremely low CCD output is detected in some parts of the line, the machine assumes this is due to abnormal black lines on the white plate. This low output is corrected using neighboring pixels. To switch off this correction, use SP4-918 (for the original modes known as �Service Mode�) and SP4-942 (other original modes).
Black Line Erase Compensation
In ADF mode, if extremely low CCD output is detected on the scanning line before the leading edge of original arrives there, this is attributed to abnormal black dots on the exposure glass. This low output is corrected using neighboring pixels. To adjust or switch off this correction, use SP4-919 (for the original modes known as �Service Mode�) and SP4-943 (other original modes).
