1. Press “Next” or and let the scanner display the Screen 31.
Screen 31
2. 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 fi-
4340C 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 IPC-4D(IMGGE PROCESSING CIRCUIT BOARD) support of those functions is intended for
compatibility with the IPC-3/3D (except for image quality). 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.
