At Screen 31, press or to select "Standard" or "IPC4D". When "Standard" is selected, the scanner uses its built-in image processing. On the other hand, the scanner selects the image processing of the IPC-4D(IMAGE PROCESSING CIRCUIT BOARD) when the "IPC-4D" is installed and selected. NOTICE The factory default is "Standard". NOTICE fi-4340C has built-in Image Processing. The following image processing is supported both by the fi4340C and the IPC-4D(IMAGE PROCESSING CIRCUIT BOARD). As a default, the scanner built-in functions are enabled. By setting "On" using the Operator Panel, the IPC-4D image processing overrides the built-in functions.

The matrix size used in the IPC-4D(IMAGE PROCESSING CIRCUIT BOARD) is larger than the one in the fi-4340C. The fi-4340C Built-in Dynamic Threshold is a new algorithm. 15 Adjust ADF Erasing Edges 1.
