Abstract

In a Multifunction Printer (MFP) or a low volume printer, certain subsystems are designed as Customer Replaceable Units (CRU) making it easier and faster to service the machines when parts need to be replaced. Currently, the marking and fusing subsystems are bundled together and sold as one CRU. With advancements in long life fusing, the fusing subsystems may last much longer than the marking system, especially in office class devices with relatively low Average Monthly Print Volumes (AMPV) and short cycles. This means that fuser subsystems may be replaced more frequently than needed, when servicing the marking subsystem. This proposal is to divide the existing (marking/fuser) CRU in two and make it possible to service them separately. In this case the fuser would be one subsystem and the marking system would a CRU. The fusing and marking subsystems could be replaced at different intervals or as needed individually. Typically the marking system would be replaced more frequently than the fuser. In order to accomplish this, the fuser subsystem would need to be designed as a separate independent subsystem and the marking system would be designed as a CRU.

Marking System Replaceable Unit for Multifunction Printer

In a Multifunction Printer (MFP) or a low volume printer, certain subsystems are designed as Customer Replaceable Units (CRU) making it easier and faster to service the machines when parts need to be replaced. Currently, the marking and fusing subsystems are bundled together and sold as one CRU.  With advancements in long life fusing, the fusing subsystems may last much longer than the marking system, especially in office class devices with relatively low Average Monthly Print Volumes (AMPV) and short cycles.  This means that fuser subsystems may be replaced more frequently than needed, when servicing the marking subsystem. This proposal is to divide the existing (marking/fuser) CRU in two and make it possible to service them separately.  In this case the fuser would be one subsystem and the marking system would a CRU.  The fusing and marking subsystems could be replaced at different intervals or as needed individually.  Typically the marking system would be replaced more frequently than the fuser.  In order to accomplish this, the fuser subsystem would need to be designed as a separate independent subsystem and the marking system would be designed as a CRU.

New fusing technologies are aimed at long life by design of long life fusing roll and pressure roll with web oiler/cleaner CRU. Examples of the fuser roll include anodized aluminum, with life estimate of 4 million prints. Examples of the pressure roll includ...
