Abstract: Methods and apparatus provide for automatic fluid ejector alignment and performance evaluation and modification in one or multiple planes. A fluid ejector fires a drop through a drop detection module. A signal indicating drop presence or absence is sent to a computer. The computer analyzes the data, and makes a compensation determination of a preferred method of using the fluid ejector. The compensation determination may include electronically modifying the image data to be printed, physically manipulating the fluid ejector, completely skipping the fluid ejector during printing operations, or in some other way modifying the fluid ejector or image data such that apparent printed image error due to fluid ejector alignment or performance error is reduced.

During translation of the print head relative to the transfer surface, the first contacting member maintains a sliding contact with the first receiving member.

Abstract: A drive assembly for a printer includes an endless loop drive path and guide structure that allows a printhead to operate in either reciprocal or endless loop modes in which the printed traverse both a liner and an arcuate portion of the drive path. This provides a printer architecture in which a printhead may be endlessly driven at a constant speed in one direction to provide multiple print swaths separated spatially. This eliminates the need for decleration/acceleration changes required in reciprocal printer architectures and is capable of increased throughput by defining arcuate turnaround zones that can be traversed by the printhead faster than the time it takes to slow, stop and reverse a conentional reciprocal printhead assembly. This robust printer architecture also allows flexibliity in use of multiple printheads with simultaneous printing, simultanouse both side printing, and duplex capabilities.

Abstract: Methods for automated uniformity assessment and modification of image non-uniformities using an image measurement device capable of determining image reflectance and/or transmitter as a function of position, such as a spectrophotometer, a calorimeter, and/or a densitometer. One or more of these devices scan an image on a substrate, such as a sheet, thereby generating data representing image characteristics, such as, for example, image non-uniformity. The sheet may contain a reference/test pattern including one column, strip or patch intended to have a uniform density. This data generated by the device after the scan of the substrate is analyzed with signal processing algorithms for image characteristics assessment, including image spatial uniformity and compared to reference image characteristics including image spatial uniformity. An image modification profile may be generated to be applied to a marking system to thereby alter subsequent image data and improve image spatial uniformity of the marking system.

Abstract: A system and method that converts legacy and proprietary documents into extended mark-up language format which treats the conversion as transforming ordered trees of one schema and/or model into ordered trees of another schema and/or model. In embodiments, the tree transformers are coded using a learning method that decomposes the converting task into three components which include path re-labeling, structural composition and input tree traversal, each of which involves learning approaches. The transformation of an input tree into an output tree may involve labeling components in the input tree with valid labels or paths from a particular output schema, composing the labeled elements into the output tree with a valid structure, and finding such a traversal of the input tree that achieves the correct composition of the output tree and applies structural rules.

The method generates a halftone line screen having multiple levels, each level having multiple line segments, each line segment having an equal pre-determined number of elements.

The method then assigns threshold values to pixels corresponding to a first element within the multiple line segments of the remaining levels of the halftone line screen according to the first element stochastic fill sequence.
