Components Layout of Scanframe Assy
The Scanframe Assy plays a role of supporting each Assy at the above, consisting of flat
cables from CIS, USB ports, photo sensors, wiring harness and OP harness.
Driving CIS
There is need to drive CIS for scanning or flatbed scanning. When the motor rotates, the
torque and rev count move the timing belt thru gear pulleys connected to the drive gears.
The timing belt is connected to CIS frame which is adjusted by the movement of the timing
belt. The CIS home position is defined by activating the photo sensor with a specific area of
the CIS frame, and the CIS can be carried a specific distance to ADF scan position from the
