Abstract: A method for reducing artifacts on a toned sheet caused by buckling during fusing includes providing two compliant rollers that form a fusing nip for fusing the toned sheet. A control drives at least one of the rollers at a nominal speed to cause the rollers to rotate and there after increasing the roller speed to high speed prior to the sheet arriving at the fusing nip and after the sheet is in the nip decreasing the drive speed back to the nominal speed.

Abstract: A method of synchronizing the timing of a plurality of physically coupled print engines using a small delta time increment. According to the first mode of practice, the second electrophotographic module, designated as E2, is started at a slower operating speed than its normal run speed. The PI control algorithm that controls the motor speed will then allow the speed of E2 to reach its nominal speed.

Abstract: A print engine synchronization method enables the movement of a first print engine dielectric support member (DSM) having one or more image frames as well as the movement of a second print engine DSM having one or more image frames by monitoring a first frame signal from the moving first print engine DSM and a second frame signal from the moving second print engine DSM. An offset is determined for each of corresponding pairs of frames from the one or more image frames of the first and second print engine DSM and the determined offset for each corresponding pair of frames is compared to a target offset to maintain synchronization between the first and second print engines on a frame by frame basis by adjusting a second print engine DSM velocity based on the comparison of the determined offset and the target offset.

Abstract: A method of improving the synchronization of the timing of a plurality of physically coupled print engines by detecting and eliminating misleading indications of a non-synchronized print engine that are essentially minimal variations caused by disturbances to the printer such as torque disturbances, power line voltage or frequency variations, etc. using a chosen number of consecutive changes in the time delay to result in the time delay of the receiver being handed off from one engine or module to a sequential engine or module before a machine error is declared. This method notes that a speed variation is sufficiently large or if a signal is reported that a module, operating within its speed specifications but near the end the limit of that specification, had been subjected to a small incremental change in module speed resulting in that module operating outside its specifications and takes corrective actions or not depending on the magnitude and or source of the variation.
