9.2.2 Manual Feed Pickup Mechanism
The manual feed pickup is a mechanism to pick up and feed the paper loaded on the manual feed tray into the machine one by one.
The pickup condition is detected by the following sensors or switch.
- Cassette detection switch (SW2): Detects the presence/absence of the cassette.
- Manual feed paper sensor (SR707): Detects the presence/absence of the paper on the manual feed tray.
- Registration sensor (SR710): Detects the lead edge of the fed paper.
- Paper displacement sensor (SR714): Detects the paper displacement.
MEMO:
Since a cassette is included in the feed path for manual feed pickup, it is necessary to attach the cassette when manual feed pickup is performed.
Up to 100 sheets of paper (75 g/m2) can be fed from the manual feed pickup inlet.
Manual feed pickup operation
1) The main controller sends a print command to the DC controller.
2) The DC controller drives the pickup motor (M4).
3) The DC controller turns ON the manual feed pickup solenoid (SL5013).
When the drive is sent from the pickup motor, the manual feed pickup roller rotates.
In this condition, double-fed paper is removed by the separation pad, and the paper is fed one by one.
4) The paper is transported to the ETB unit after the skew is corrected by the registration roller and registration shutter.
