Abstract: An imaging system, which may be applied both to black and white and color imaging systems and comprising a platen member which defines an imaging portion and a calibration portion is disclosed. The imaging portion and the calibration portion comprise separate portions of the platen member. The platen member is supported by a movably mounted support member, and moves with the support member between a platen member calibrating position and a platen member imaging position. The platen member is dimensioned to support a sheet to be imaged. An imaging module with an imaging zone is supported in a position where the imaging zone is positioned to coincide with a portion of a sheet supported on the imaging portion of the platen member, when the platen member is in the platen member imaging position. A calibration member having a reference reflectivity is adhered to the calibration portion of the platen member.

Abstract: A magnetic latch mechanism and related process for easily and reliably performing a latch operation by moving a magnetically attractive catch plate into and out of engagement with a magnetic field. When in engagement, the latch is secured. When the catch plate is moved away from engagement, the latch can be opened. A magnetic latch for a marking system, particularly for panels covering paper path and jam clearance mechanisms.

Abstract: In a document feeder with a superposed sheet input tray and sheet output stacking tray for feeding and then restacking print media paper sheets of variable dimensions, the lateral setting (repositioning) of the at least one variable position side guide of the input tray to the sides of the input sheets automatically correspondingly resets the corresponding side guide of the underlying output stacking tray, to reduce sheet scattering in the sheet stacking, especially skewed sheets. This may be accomplished by a simple direct mechanical integration of these respective side guides into a single repositionable component with upper and lower extending sheet edge guide portions.

Abstract: A lift and interlock actuator mechanism for installing a CRU in a printing machine. There is provided a lift and interlock actuator mechanism which has a sliding planar member which is moved from a first position to a second position to remove and/or install a feed head CRU in a printing machine. The planar member creates an interlock which prevents the CRU from being removed or installed when the corresponding drive components are in the wrong position. Sliding of the planar member disengages a drive coupling from the CRU and also causes a lift mechanism to pivot the CRU about the drive shaft causing the CRU to be moved to a position for easy removal. To install the CRU the planar member is slid to the second position the CRU is placed into position and rotated down, allowing the planar member to slide back to the first position. This sliding allows the drive coupling to mesh and allows the CRU to rrotate into the home position.
