Scanner Mechanism

CIS (Contact type Image Sensor) Type Sensor Scanner
  • CIS means “Contact type Image Scanner”: the CCD sensor has the same length as the document width.
  • The reflected light from the document comes directly into the CCD surface through a lens.

  • A: Lamp
  • B: Lens
  • C: CCD (CCD contacts on the surface of a CIS board.)
  • D: CIS module
  • E: Document
  • F: Document glass
  • G: Motor

The CIS module consists of;

  • A: Lamp
  • B: Lens
  • C: CCD (CCD contacts on the surface of a CIS board.)
Scans with three CIS sensors.
  • After the scanning operation starts, the sub-scanning total magnification correction value is calculated, and the endurance deterioration correction value is calculated.

  • Detect paper tilt/width, and feed paper from paper standby position to scan CIS sensor.

  • Scan the target image with 3 CIS sensors.

  • Carry out paper transport until the target scan operation is completed, and then end.
