Flatbed scanning
# Part
1 Scanner home position
2 Document size detection position
3 Scan start position
4 Scanner lamp
5 Trailing edge of the image
The motor (scanner drive) drives the scanner lamp to move to the home position when the printer is turned on.
When the ADF is opened and a document is placed on the scanner flatbed, the sensor (ADF open) detects that the ADF
is open. The scanner lamp moves to the original size detection position. The sensor (scanner media length 1 and 2)
detects the length of the document and the scanner CCD lens assembly detects the width of the document. The scanner
lamp then moves and stops at the scan start position.
When the start key is pressed, the scanner lamp moves from the scan start position to the leading edge of the document.
The scanner lamp starts scanning the document from the leading edge and finishes scanning at the trailing edge.
The LED turns off when scanning is complete. The scanner lamp moves from the position on the trailing edge of the
document to the home position, and then to the document size detection position.
