摘要： An image forming device and method of detecting the presence or absence of components of one or more image forming units. Each image forming unit includes a replaceable component. A power supply transmits an input signal to the replaceable component. A detection circuit is coupled to the replaceable component and generates an output signal indicative of the presence or absence of an electrical coupling that is established when the replaceable component is installed. The detection circuit thus senses the input signal propagating through the replaceable component. A controller may be adapted to halt image formation or generate an error indication if the detection circuit detects the absence of necessary components or the presence of components not necessary for a current mode of operation.

摘要： An ink jet printhead voltage fault protection apparatus includes a power supply and a latching circuit. The latching circuit disables a printhead voltage applied to the printhead by the power supply upon detection of a fault condition associated with the printhead voltage such that the printhead voltage remains disabled until the power supply goes through a power-on reset sequence.

摘要： An image transfer assembly in a color printer or the like includes four image forming units. Each of the image forming units includes a photoconductive unit and a transfer device. A voltage is applied to the transfer device thereby creating a voltage potential between the photoconductive unit and the transfer device to facilitate the transfer of toner to a media substrate, such as paper. The transfer devices in the first two image forming units share a single high voltage power supply while separate high voltage power supplies supply the necessary voltage to the transfer devices of the other two image forming units.
