B1.02E1: Close upper paper path
Initial Steps
1. „Horizontal wiring diagram" auf Seite 2283
HINWEIS: Set DVM to the appropriate range for the voltage.
VORSICHT! Careful working around electricity.
Moving parts can cause injury.
ACHTUNG: Do not use frame as ground.
Test the Horizontal Open sensor (SN4)
1. Open and close the horizontal jam access guide to manually activate SN4.
TIPP: Click Subsystems, click Paper Path, and then click Horizontal Transport.
Does the sensor state change?
No Yes
Check the alignment of the horizontal jam access
1 1. Check the alignment of the Horizontal Open sensor (SN4) actuator alignment and the horizontal jam access guide latch.
Check the following conditions
1. Verify that the sensor is correctly located.
2. Verify that all of the idler rollers are correctly seated and that the drive roller surfaces are free of defects.
3. Clean the sensor and the surrounding area.
4. If the sensor has a flag actuator, check that the flag actuator has free movement.
5. Check the wire harness between the Horizontal Open sensor (SN4) and the Motion PCA (A2).
