    摘要: An image forming apparatus comprises a container, a supplier, a conveyor, a grammage detector, a sheet detector, an image former, and a processor. The processor set a flag when the detected grammage exceeds a first grammage, measures a conveyance time of a sheet to the sheet detector, determines a conveyance delay of the sheet based on whether the conveyance time is greater than or equal to a first amount of time, counts a number of occurrences of the conveyance delay in a state where the detected grammage exceeds the first grammage, and prohibits supply of sheets from the container when the detected grammage exceeds a second grammage larger than the first grammage or the number of occurrences of the conveyance delay is greater than or equal to a threshold value.

    摘要: A printer for printing to electrically printable media is described. During printing, a drum surface having first and second portions is charged to a first voltage, and the second portions of the surface are selectively discharged. A transfer electrode has a uniform voltage applied thereon. A first erase electrode and a second erase electrode have a fixed voltage differential between them. The printer receives the electrically printable medium between the first erase electrode and the second erase electrode to expose the electrically printable medium to the fixed voltage differential, and to move the electrically printable medium proximal to the drum and the transfer electrode to expose the electrically printable medium to a first voltage differential that results from the first voltage of the first portions and the uniform voltage, and a second voltage differential that results from the second voltage of the second portions and the uniform voltage.

    摘要: A fuser system of a xerographic device includes at least one set of a fuser member and a pressure member having a nip width therebetween, the nip width being set to within a specification nip width range, at least one sensor for monitoring the velocity of at lease one of the fuser member, the pressure member and a media passing through the nip, a processor that receives the velocity data from the at least one sensor and that determines a current nip width from the velocity data and compares the current nip width to the specification nip width range, and a nip width adjustment device in communication with the processor, which adjusts the current nip width to be within the specification nip width range. To offset changes in nip width due to hardening/softening of a fuser member material, or to provide a means to measure nip width in order to enable fusing setpoints using multiple nip width specifications, a method for closed loop control of nip width is enabled by the fuser system.
