Problems solved by technology

This can lead to signal degradation and ultimately poor jetting performance
In order to protect the signal, the system must use expensive and large service loop cables, which can greatly increase the system cost

Embodiment Construction

[0008] figure 1 A system diagram of a printing system 10 is shown having a dual shuttle system, a first more precise printhead shuttle 14 mounted on a print rail 26 carrying the printheads 12, and a second more precise printhead shuttle mounted on a separate common rail 28. Inaccurate, more likely heavier common shuttle 16. Common shuttle 16 contains the electronics that generate the waveforms used to cause printhead 12 to dispense ink onto printing surface 32 . The shuttles traverse the printing surface 32 while the printheads selectively deposit ink as determined by image data sent from the system controller 22 and formatted by electronics on the common shuttle 16 . The printhead uses the image data to determine which nozzles are connected to the waveform generated by the electronics on the common shuttle. Controller 22 may take the form of a computer or other computing device. It transmits the image data to electronics carried on a common shuttle 16 which generates wavef...

Abstract

The present invention relates to printhead reciprocation with higher precision. A printing system having a printhead shuttle including a printhead mounted on a print rail, a support including support electronics for the printhead mounted on a support rail adjacent and parallel to the print rail a shuttle, and at least one electronic signal-carrying cable connected between the support electronics and the printhead.

Description

technical field [0001] The present disclosure relates to printing systems, and more particularly to printing systems that pass a print head or heads across an image receiving surface. Background technique [0002] Many inkjet printing systems pass the printhead across an image receiving surface, such as paper or cloth. For precise imaging motion, which results in precise ink placement to obtain high quality images, it is desirable to minimize the mass of the printhead and its associated close proximity parts with which the head travels. The close proximity portion usually consists of electronics that generate image forming signals and transmit them to the printheads to cause the printheads to eject ink. [0003] If the electronics were on the shuttle with the printhead, it would add weight which could lead to inaccuracies. If they are located elsewhere in the printing system, such as at fixed locations near the path of the printhead, the inkjet drive waveforms must travel ...
