Abstract
A xerographic printer or copier includes a replaceable cartridge having a cleaning blade and carrier particle pickoff member associated with a rotating charge receptor. As the cartridge is being used, carrier particles removed from the photoreceptor by the cleaning blade are magnetically retained on the pickoff member, where the remain for the balance of the lifetime of the cartridge. When a useable lifetime of the cartridge is spent, the carrier particles are removed from the pickoff blade.
Claims16
A cartridge for operating within a xerographic printing apparatus, comprising:
- a blade for engaging a rotatable charge receptor;
- a pickoff member, having magnetic properties associated therewith, disposed near the photoreceptor, the pickoff member magnetically retaining carrier particles thereon for a lifetime of the cartridge.
A method of operating at least one xerographic printing apparatus, comprising:
- removing from a xerographic printing apparatus a cartridge, the cartridge including a blade for engaging a rotatable charge receptor and a pickoff member disposed near the blade and photoreceptor, the pickoff member magnetically retaining carrier particles thereon;
- and
- removing retained carrier particles from the pickoff member, using a wiper which is not part of the cartridge.
