A system and associated methods are provided for the evaluation of printing systems. Results may be expressed as a set of simple-to-understand alphabetic grades (e.g., A, B, C, D, F). These grades reflect the visual acceptability of prints of the image evaluation document produced by the printing system. Capabilities are provided for query and reporting of data across printing systems and over time for various attributes and factors.

Method for evaluation of printing and imaging systems that grade attributes of an image evaluation document produced by such systems

An apparatus and method for adjusting color and gray balance in a color printer, wherein a multicolored output sheet including a set of printer color balance adjustment instructions for performing color balance adjustments processor is produced by the print engine. A processor provides a color balance judging indicator, from to a scanned test pattern sheet in the case of a copier or from a memory electronically storing a test image. A controller is used to for transmit the set of printer color and gray balance adjustments to the processor.

A method of manufacturing dust-free spheroidized magnetite beads comprising the steps of introducing raw magnetic ore particles in the presence of an inert non-oxidizing carrier gas to a carbon arc plasma flame assembly to which is fed a controlled amount of nitrogen and argon gas, melting the ore particles to form spheroidized droplets thereof, allowing the spheroidized droplets to fall by gravity in a chamber having a controlled atmosphere while at the same time sweeping the inside chamber wall with a vertical flow of air or an inert gas and providing a horizontal curtain of air or an inert gas at a specific location within the chamber to remove dust formed in the process. The droplets are cooled forming beads of ore, which may be used as a xerographic carrier without further processing.
