Abstract

An apparatus and method for removing the customer replaceable cleaner subsystem from an electrostatographic printing or copying machine without spillage of toner and other debris particles is disclosed. The cleaning subsystem is a hybrid of a disturber brush and a retractable cleaning blade. The cleaning unit is slidably inserted or removed from the machine. The cleaning unit is removed from the machine when a cleaning failure occurs and replaced by a readily available spare cleaning unit. When the cleaning unit is inserted into the machine, adjacent to the photoreceptor, the door panel is slidably opened as the cleaning unit is moved into the appropriate space. The blade is moved into an engaged position in contact with the photoreceptor for cleaning. When the cleaning unit is removed from the machine, the blade is retracted and the door panel is slidably closed as the cleaning unit is being removed, providing self-sealing of the cleaner unit and preventing toner and other debris spillage.

REPLACEABLE CLEANER SUBSYSTEM THAT PREVENTS PARTICLE SPILLAGE (Cont'd)

An apparatus and method for removing the customer replaceable cleaner subsystem from an electrostatographic printing or copying machine without spillage of toner and other debris particles is disclosed. The cleaning subsystem is a hybrid of a disturber brush and a retractable cleaning blade. The cleaning unit is slidably inserted or removed from the machine. The cleaning unit is removed from the machine when a cleaning failure occurs and replaced by a readily available spare cleaning unit. When the cleaning unit is inserted into the machine, adjacent to the photoreceptor, the door panel is slidably opened as the cleaning unit is moved into the appropriate space. The blade is moved into an engaged position in contact with the photoreceptor for cleaning. When the cleaning unit is removed from the machine, the blade is retracted and the door panel is slidably closed as the cleaning unit is being removed, providing self-sealing of the cleaner unit and preventing toner and other debris spillage.

The printing apparatus with the cleaner subsystem for removing particles from a surface comprises means for cleaning the particles from the surface; a housing defining an open ended chamber, the cleaning means being mounted in the chamber of the housing with a portion thereof being adapted to extend from the open ended chamber into contact with the surface; and a cover mounted movably on the housing and being adapted to move between a position closing the open ended chamber to a position opening the open ended chamber in response to the cleaner subsystem being inserted into the printing apparatus.

The method of installing the cleaner subsystem adjacent to an imaging surface of a printing machine, comprises the steps of inserting the cleaner subsystem into the printing machine; and opening a chamber of the cleaner subsystem, in response to the cleaner subsystem being inserted into the printing machine, to enable a cleaning member to extend from t...
