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. To operate the feed head a soloenoid moves the CRU into a feed position which places the nudger roll on a stack of sheets to be fed. The lift and interlock actuator mechanism described herein allows for easy one handed removal of the CRU and prevents the CRU from being improperly installed.
