A digital printing system employing tandem marking engines for duplex printing utilizing a variable dwell time in the output sheet inverter of the first marking engine to provide correct positioning of the leading edge of the inverted sheet for arrival at the entrance of the second marking to avoid the seam in the photoreceptor.

Controlling sheet registration in a digital printing system

Disclosed are embodiments of a modular printing system with one or more modules having one or more bypass paths and comprise a modular printing system with a module (e.g., a stacker or feeder module) having a main compartment and at least one additional compartment. Contained within the main compartment is a main sheet transport path and a functional component (e.g., a sheet stacking device or a sheet feeding device) connected to the main sheet transport path. Contained with the additional compartment is a bypass path. The bypass path allows sheets to be routed through the module in the event of a print media sheet jam in the main sheet transport path. Because the bypass path is contained within a separate compartment, the jam can be cleared from the main compartment without cycling down the printing system, thereby allowing for continued productivity.

A method for aligning an endless belt having an optimum position within an acceptable range on associate guide rollers in a machine by manually placing the belt over an outboard end of the guide rollers and sliding the belt inward over the guide rollers to a first rough position. When it is determined that the belt has reached an acceptable range of positions, the belt is steered inward using a given operational steering angle. When it is determined that the belt has reached an optimum position, the belt is driven at an operational speed and steered inward and outward to maintain the optimum position.
