3.3 SSI & Regi Assy
- SENSOR PHOTO (SSI No Paper Sensor: PL3.2.13)
The SSI No Paper Sensor detects the presence/absence of print media in the SSI tray by the 
change in the actuator position.
Upon detecting the sheet, the Regi Roll rotates for a predetermined duration to feed the sheet. The 
sheet is fixed between the Rolls so that it may not fall from the SSI.
The Rolls stop immediately when the Regi Sensor detects the presence of paper.
