Ssi & Regi Assy - Dell 2130cn Service Manual

3.3 SSI & Regi Assy
- SENSOR PHOTO (SSI No Paper Sensor)
Detects presence/absence of paper in the SSI tray by the change in actuator position.
- SSI No Paper Sensor
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.
- SENSOR PHOTO (Regi Sensor)
It detects when the paper front end reaches the CHUTE ASSY FDR REGI.
When the paper feeds from the SSI, Regi Sensor is measuring the paper length (size).
The ON time of Regi Sensor is converted into the paper length.
ON: The paper activates the actuator.
- Regi Clutch
CLUTCH ASSY REGI transmits the driving power from the DRIVE ASSY MAIN to ROLL ASSY
REGI, and transports the paper from the tray and SSI toward the PHD unit direction.
DRIVE ASSY SUB)
The timing of sheet feed from the Regi Assy is adjusted by the duration of the Regi Clutch operation
so that the toner image on the drum can be transferred to the appropriate position on the sheet.
