Delivery is a mechanism to deliver the paper transported from the fixing assembly to the delivery tray.
The following sensors detect the paper condition.
- Fixing delivery sensor (SR6005): Detect the paper delivered from the fixing unit.
- Reverse sensor (SR706): Detect the paper transported to the reverse assembly.
- Delivery sensor (SR715): Detect the paper transported to the delivery tray.
- Delivery paper full-level sensor (SR713): Detect the stack volume of paper delivered to the delivery tray.
Delivery operation
1) The fixed paper is delivered from the fixing unit.
2) When a certain period of time elapses after the fixing delivery sensor (SR6005) detects the lead edge of the paper, the duplexing feed motor (M10) and the reverse
motor (M11) rotate forward.
The paper moves to the reverse assembly while pressing up the self-weight flapper.
3) When a certain period of time elapses after the reverse sensor (SR706) detects the lead edge of the paper, the reverse motor (M11) stops.
This certain period of time varies depending on the paper length.
The paper which passed through the reverse roller before the reverse motor stopped is temporarily stored at the back of the machine.
4) The reverse motor rotates in reverse.
When the reverse motor rotates in reverse, the paper is transported to the opposite direction.
