DP120F/DP125F Circuit Description
3.18 Scanner Cover Open Detect Circuit
The scanner cover open detect circuit consists of the PTC GA (IC45) and other peripheral
devices. It detects the output of the scanner cover open switch connected to CN5 on the
Mother PBA to detect the cover open or closed state of the scanner cover.
When the scanner cover is closed, the scanner cover open switch is pushed down by the hook
of the scanner cover and turns on. This causes the DOOR signal to be LOW and input to the
PTC GA to detect that the scanner cover is closed.
When the scanner cover is open, the scanner cover open switch turns off and the DOOR signal
goes HIGH. Then, when the PTC GA detects that the cover is open, the message “SCANNER
COVER OPEN” will be displayed on the LCD of the Operation panel PBA.
