    摘要： A method and apparatus saves on toner cost and improves productivity for running registration and color process controls in a printer by making dual use of patches for both functions. That is, the small patches normally used only for registration measurement are also used for xerographic process control measurements, thereby eliminating the need for large patches and obtaining registration information and color control information at the same time. The dual use of small patches to measures both registration and color process control is made possible by periodically establishing correlation between the density of large density patches and the smaller registration patches.

    摘要： A process control method for color quality control maintains a preselected developed mass per unit area (DMA) of black solid area by adjusting the development field during run-time operation. In order to estimate the DMA of a solid black control patch, which is outside the sensing range of an infra-red densitometer (IRD), an estimation technique is employed which accounts for system changes due to adjustment of the development field. The estimation technique includes generating two or more test patches, using a patch generator, which have DMA readings within the sensing range of the IRD. The DMA readings and corresponding development voltages of the test patches are sensed and used to calculate a developability curve. The developability curve is projected into a region beyond the sensing range of the IRD. From the developability curve, the DMA of the solid black control patch is estimated and employed in a closed feedback loop to return the system to the preselected DMA by adjusting the development field. Development field control provides faster response to toner density changes than toner concentration control, and thus, results in better color quality control.

    摘要： An apparatus (100) for measuring toner concentration in a developer contained in a developer housing (10) includes a developer sample container (102) that receives a portion of developer extracted from the developer housing (10). A spectrophotometer (112) measures spectrophotometric data for the portion of the developer in the developer sample container (102). A processor (116) estimates the toner concentration based on the measured spectrophotometric data and a pre-determined relationship (118) between the spectrophotometric data and the toner concentration. A method (200) for estimating the toner concentration in a developer comprising a toner and a carrier includes measuring (220) a color characteristic of the developer, comparing (222) the measured color characteristic with a pre-determined relationship between the color characteristic and the toner concentration, and estimating (226) the toner concentration based on the comparing.
