Abstract

A simplified retraction mechanism for retracting the cleaning blade assembly from the photoreceptor drum of a xerographic copier. Cleaning blade assembly S is biased out of contact with the photoreceptor surface of drum 6 by compression spring 7 working through blade lever 8. Spring 7 is disposed between plunger 11 of solenoid 10 and the housing 9 of solenoid 10.

A simplified retraction mechanism for retracting the cleaning blade assembly from the photoreceptor drum of a xerographic copier. Cleaning blade assembly S is biased out of contact with the photoreceptor surface of drum 6 by compression spring 7 working through blade lever 8. Spring 7 is disposed between plunger 11 of solenoid 10 and the housing 9 of solenoid 10.

During copier operation, solenoid 10 is energized to compress spring 7 and permit blade assembly 5 to move into operative contact with drum 6. On de~energization of solenoid 10, spring 7 raises plunger 11 to engage lever 8 and move cleaning blade assembly 5 to the out~of-contactposition.

The simplified structure reduces linkage interference and the number of links required while facilitating adjustment of the operating gap 12 between solenoid plunger 11 and blade lever 8.
