International Classification:

G03G 15/20

US Classification:

399322, 399329

Abstract:

A split drives system for a printer in which a single drive motor drives a first belt drive system for the image fusing system and a second and separate belt drive system driving the sheet registration system. This split drives system mechanically isolates the second and separate belt drive system from torque fluctuations in the image fusing system via the first belt drive system driving the image fusing system. Also, the split driving system can isolate torque variations in the driving of the print media fuser from the driving of the print media sheet transport.

Abstract:

An imaging module mounting apparatus is provided to improve dynamic performance without creating an overconstraint condition causing misalignment of the imaging module. Three solid mounts are used to establish and maintain critical location datums of the imaging module. A single or plurality of variably flexible mounts are used, depending on the size of the module, to maintain alignment while minimizing any overconstraint condition caused by the imaging module being distorted out of plane due to thermal distortion and/or static distortion of the mounting frame due to movement of the machine. The variably flexible mount is filled with a high-viscosity silicon polymer. Due to the high-viscosity of the medium, the mount does not respond to fast or high-frequency vibration and appears to be a rigid mount with regard to such movement. The mount will react to very low frequency or static distortion such as that caused by movement of the machine and/or thermal distortion and maintain the imaging module in the proper position to prevent perceptible image defects.
