IBM CF Series manual

turned off since the splice has been adjusted to the sub-pixel level at the factory. Note that the host scan software can override this scanner setting.

<3> PIXEL SOURCE: The two choices are the cameras and a bar generator. The bar generator is located on the CALS Board and produces a set test pattern for diagnostic purposes. The host scan software can change this setting.

NOTE: The bar pattern is useful for troubleshooting because it isolates the “front end” electronics -- the CCD cameras and the Video Board from the rest of the scanner. If the bar pattern is good, the problem is either in the cameras or Video Board. If the pattern is bad, the problem most likely occurs after that point.

<4> NUMBER OF RESOLUTIONS: The scanner can store upto 8 preset resulutions. The number of resolution stored is depends on the model. (do not alter this parameter)

<5> GRAY SCALE ON/OFF: When gray scale is on, the scanner will output eight bit data for each pixel. Otherwise, it will output binary data with one bit per pixel. The host scan software can change this setting.

<6> NUMBER OF DOCUMENT SIZES: The scanner can store upto 8 preset document sizes (active scan widths). Typically, five of these values are set for standard document sizes A through E, while the remaining three are not used. The actual document sizes are defined under option G of the Diagnostic Tests menu. The host scan software can override this setting.

<7> CCB WINDOW START: This parameter adjusts the starting location of line scans. It is adjusted to start scanning at the zero line on the document table at the factory. (do not alter this parameter)

<8> DISPLAY SYSTEM: This parameter indicates if the scanner is equipped with a display system.

<9> MIRROR: This parameter when active outputs the mirrored image. This is controlled by the host scan software.

<A> DEFAULT ZOOM STATE: The scanner display option can be set to be either “zoomed in” or “zoomed out” as the default.

<B> AUDIO LEVEL: This sets the audio level of the scanner. It has a range of 0 to F. The factory defalt is A.
