3.2.1 Scanner unit
The scanner unit is equipment which scans the paper using the CCD unit. This machine
prints the scanning data (copy) or data is sent by fax (fax transmission).
There are two kinds of scanning method of the scanner unit. One is operation to scan with
the scanner unit, the paper is placed on the document glass, the CCD unit moves is the
bottom of it, and it scans the paper, and other is operation to scan in connection with the ADF
unit, scan the paper which has been sent over the immovable CCD unit.
1. CCD unit
The CCD unit includes the charge coupled device (CCD) sensor (Resolution of horizontal
scanning: Max 600dpi, color scanning). The cold cathode fluorescent lamp lights the
document, and the reflection from the scanned image data is transferred to the lens by
the mirror. The lens reduces the scanned data so that the image is generated on the
CCD.
2. Driving of the CCD unit
The CCD unit is supported by the CCD rail and assembled on the CCD drive belt. When
the CCD motor is rotated clockwise, the CCD unit on the CCD drive belt scans the
document while sliding to the right hand side. In this case, the CCD unit has the capacity
to scan at 2,400dpi resolution of sub scanning .
3. CCD unit home position detected (FB home position detected)
The CCD unit is configured at the FB home position to determine the scanning position of
the sub scanning direction. Based on the home position, the position performing the
white level compensation or the scan lock other than the scanning position is configured.
The FB home position is detected when the CCD unit intercepts the home position
sensor in the left side of the inside of the scanner unit.
4. White level compensation
Whenever the variation of the CCD unit by CCD unit, the correction of the time
degradation and the value of the while color scans, in order to make them not different.
The white level compensation keeps a fixed value of the white color by scanning the
white-level reference film inside the scanner unit with the CCD.
5. Function of scanner lock lever
The CCD unit is fixed so that the CCD unit moves and may not be damaged when
product transfer.
