    摘要: Fusers for fusing toner on media, printing apparatuses, and methods of fusing toner on media in printing apparatuses are disclosed. An exemplary embodiment of the fusers comprises a fuser roll comprising a fusing imaging surface; at least one heating element for heating the fuser roll; a pressure roll including an outer surface, the outer surface and the fusing imaging surface defining a nip; a temperature sensor for sensing a temperature on the fusing imaging surface; a time delay calculator connected to the temperature sensor; a feedback controller connected to the temperature sensor and the heating element, the feedback controller receives a signal from the temperature sensor indicating the temperature on the fusing imaging surface and controls the heating element based on the temperature; and an open-loop controller connected to the heating element and the time delay calculator. The open-loop controller receives a time delay signal from the time delay calculator and bypasses the feedback controller to control the heating element to increase the temperature of the fusing imaging surface starting at about a time, t−Δt (where Δt is a time delay), which is before a medium arrives at the nip, and continuing until about a time, t, at which the medium arrives at the nip and is contacted by the fusing imaging surface. The feedback controller resumes control of the heating element at about the time t.

    摘要: The life of the photoconductor in an image forming apparatus is typically limited by the eventual occurrence of some form of print quality defect related to the photoconductor. One of the typical failure mechanisms is the slow wearing away of the surface layer of the photoconductor. Photoconductor run life is improved by operating a charging station in a low wear mode during certain circumstances, including: during printing of a low stress page as detected based on the image data; during at least one of cycle up and cycle down operations to control charging of the at least one photoconductor over at least one print zone for at least one cycle of rotation of the at least one photoconductor; during printing of at least one test patch in a process control cycle; and upon determination from the image data that at least one photoconductor will not contribute to the printing during a next print cycle.

    摘要: A system suited to scheduling print jobs for a printing system includes a first processing component which identifies preliminary attributes of print jobs to be printed on sheets. A job scheduler receives the preliminary attributes and assigns each of the print jobs to one of a plurality of job queues in time order for printing. Print jobs spanning the same time are scheduled for printing contemporaneously. In one mode of operation, the assignment of the print jobs to the job queues is based on their preliminary attributes and on the application of at least one constraint which affects contemporaneous printing of at least two of the plurality of print jobs. A second processing component identifies detailed attributes of the print jobs. A sheet scheduler receives information on the assignments of the print jobs and their detailed attributes and forms an itinerary for each sheet to be printed.

    摘要: A printing system (10) includes at least one marking device (22A, 22B, 22C, 22D). Each of the marking devices is configured for applying images to print media. A primary fusing device (24A, 24B, 24C, 24D) is associated with each of the marking devices for applying a primary fusing treatment to the applied images to form printed media. A portion of the printed media may be only partially fused in the primary fusing treatment. A secondary fusing device (26) receives the printed media from the at least one marking device. The secondary fusing device and/or primary fusing device is addressable. A control system (90) may be operably coupled with the secondary fusing device. The control system evaluates whether the printed media is only partially fused and instructs the secondary fusing device to apply a further fusing treatment to the printed media evaluated as being only partially fused.

    摘要: Systems and methods of diagnosing a photoreceptor associated with an imaging device. The photoreceptor is configured to enter into a diagnostic cycle to complete a set number of cycles. A sensor or array is configured to a scan a component associated with the imaging device during each of the set of cycles to establish defect data. The defect data is analyzed to filter one or more charge deficient spots (CDS) from background noise in the defect data. The systems and methods determine whether the photoreceptor needs replacement based on the determined one or more CDS. The systems and methods are further configured to output a report of the determination. The determination is conducted at fixed or variable intervals throughout the life of the photoreceptor and/or imaging device.
