    摘要： A scavengeless development system for use in highlight color imaging comprises. AC biased electrodes (46) positioned in close proximity to a magnetic brush structure (56) carrying a two-component developer to cause a cloud of toner to be generated which noninteractively develops an electrostatic image. The two-component developer includes a mixture of carrier beads and toner particles. By making the two-component developer magnetically tractable, the developer is transported to the development zone as in conventional magnetic brush development where the development roll or shell of the magnetic brush structure rotates about stationary magnets positioned inside the shell.

    摘要： A printing machine (100) is arranged to detect an arcing event. An arcing detection signal (231) based on the arcing event is formed. The arcing detection signal includes an arcing detection signal frequency and an arcing detection signal amplitude. The arcing detection signal frequency value and the arcing detection signal amplitude value are used to detect the occurrence of an arcing event. Once an arcing event is detected, an arcing level corresponding to the severity of the arcing event is determined. At least one arcing remedy based on the arcing level then is performed. The arcing remedy comprises any of logging the arcing event, generating a maintenance message, performing a maintenance procedure, informing a maintenance person, dispatching a maintenance person and powering-down the printing machine.

    摘要： An apparatus which measures the usage of toner in a developer unit. A donor roll (74) receives toner material from a mixer (44). The mixer fluidizes the toner with the pressure from newly discharged toner moving the fluidized toner from one end of the developer unit to tile other end thereof. An electrical bias is applied between the donor roll and mixer. The current biasing the mixer is detected and a signal transmitted in response thereto corresponding to the usage of toner in the developer unit. This signal controls the discharge of toner into the developer unit.
