Image Scanner Unit (Isu) - Kyocera FS-1030MPF Service Manual

(2) Image scanner unit (ISU)

The original image is illuminated by the LED and scanned by the CCD image sensor in the CCD PWB (CCD-
PWB) via the four mirrors and ISU lens, the reflected light being converted to an electrical signal.
If a document processor (DP) is used, the image scanner unit stops at the position of the DP contact glass
and scans sequentially one row of the image on the original in synchronization with the moving timing of the
original in the sub scan direction by driving the DP.
