Abstract: A cleaning apparatus in a waste toner removal system of an image forming device includes a waste toner moving device that is movably mounted in a waste toner housing. The housing has an inlet where waste toner enters the housing. The toner moving device is movable between a first position and a second position to displace accumulated toner within the housing. The toner moving device is spring-biased toward the first position. A rotating actuator displaces the toner moving device from the first position to the second position to move the toner in the housing away from the inlet. The toner moving device is also self-cleaning via vibration and impact movements.

Abstract: An apparatus and method for ink-jet printing onto an intermediate drum in a helical pattern while correcting for image skew and aliasing. A plurality of ink-jet print heads place an image on an intermediate drum, impervious to ink, in a helical patter. To compensate for helical printing, the image is altered by nozzle placement and image manipulation to correct for skewing errors, and thereafter, the nozzle timing is adjusted to correct for aliasing. The plurality of print heads move parallel to the axis of rotation of the drum while the drum is simultaneously rotating, causing the image to be placed in a helical pattern. Once the entire image is placed on the drum, paper is rolled against the drum under pressure and the image is transferred thereto.
