摘要:
Controlling sheet flow in digital print engines along a paper path (42) in which the nip rollers (126,326) are driven independently by individual variable speed motors (29) and sheet position sensors (128,428) are disposed at each path gate and bend. The sensors provide sheet position and velocity signals to a controller which varies the speed of the individual nip drive motors according to an algorithm to prevent cumulative mis-positioning of the sheets and jamming.
摘要:
A compiling unit for a printing system includes a collection tray (124) and a variable-speed compiling system (126) adapted to operate at at least two speeds to thereby receive a sheet of media at a higher speed and register the sheet of media within the collection tray at a lower speed. A control system (108) is adapted to selectively operate the variable-speed compiling system at the at least two speeds. A printing system (100) having a sheet media source, at least one marking engine, such a compiling unit and such a control system is included. A method of compiling sheet media is also included.
摘要:
According to aspects described herein, there is disclosed an apparatus and method for dynamically registering an image relative to a target substrate media in a printing system. The apparatus and method including a marking engine, transport, sensing system and a correction module. The marking engine for generating the image for transfer to the target substrate media. The transport for moving the target substrate media along the path in the process direction to receive the image in a transfer area from the marking engine. The sensing system for detecting a characteristic of at least one other substrate media moved previously by the transport. Also, the correction module for altering the image generated by the marking engine based on at least one signal from the sensing system. The characteristic of the at least one other substrate media being detected from at least two portions of the path, the two portions disposed on opposed sides of the transfer area in the process direction.
