    摘要: An on-line gloss/density meter for an electrostatographic reproduction apparatus in which pigmented marking particle images are fixed to receiver members respectively by application of heat and/or pressure as such receiver members travel along a transport path through a fuser assembly. The on-line gloss/density meter includes at least one light emitter and at least one light collector, respectively mounted in operative association with the transport path so that light from the emitter, reflected from a receiver member, and is detected and a signal corresponding to such reflected light is produced. A guide element is associated with the transport path and directs a receiver member into a predetermined specified location relative to the beam of light. A logic and control unit, responsive to signals from the light collector, precisely controls operating parameters for the electrostatographic reproduction apparatus.

    摘要: A printing system includes a linehead that jets ink onto a moving print media to print a test block and an integrated imaging system positioned downstream of the linehead with respect to a media transport direction. The integrated imaging system includes an opening in a housing for receiving light reflected from a moving print media. A folded optical assembly in the housing receives the reflected light and transmits the light a distance. One or more image sensors, having known color filter arrays, within the housing each receive the light and capture one or more images of the printed test block. An image processing device is connected to the integrated imaging system for receiving pixel data from the one or more image sensors and configured to determine a color of the ink and a density of the printed test block using the pixel data.

    摘要: One or more printers or printing systems are connected to a scanning device. Each printer includes one or more color modules that are used during a printing operation. A printer prints a target for each color module or color channel. The printed targets are then scanned by the scanning device. The printed targets may be rotated to any angle and then scanned by the scanning device. The scanned raster data is processed by a controller to detect non-uniformities in at least one density image and to generate one or more correction profiles for the printer. When an image is to be printed, one or more controllers receive the image data and use the one or more correction profiles to correct or compensate for the non-uniformities during the exposure process.

    摘要: A copier/printer system includes an image scanner for scanning a document and providing, after a compression step, digital image scanning signals, P.sub.1, that may be communicated to a computer system for display and editing or alternatively communicated to a grey level printer having a magnetic tape memory. The computer system may be used to display the scanned image for editing by an operator and is coupled to the printer so that the edited image signals, P.sub.2, which may be the scanned signals and a common page description language to modify its usage, may be printed by the printer. The edited image signals, P.sub.2, may be sent to the printer over a suitable network. The printer includes image processing electronics for transforming the edited data, P.sub.2, into device independent data signals, P.sub.3. Such signals may be received by printers of the same type; i.e., those employing similar process and halftone algorithms. The signals, P.sub.3, are then converted by a look-up table in the printer to device dependent signals, P.sub.4, for printing by the printer. The signals, P.sub.3, are stored in memory which may be recirculated for making multiple copies. The memory medium storing the P.sub.3 signals may be transported or otherwise communicated to other printers of the same type for reproducing the data since the data is in common data signal or device independent form. The memory medium storing the P.sub.3 signals may also store the P.sub.1 and/or P.sub.2 signals for re-editing purposes using the computer and display.

    摘要: A multicolor reproduction is made by uniformly charging a photoconductive member, imagewise exposing that member to create a first electrostatic image, developing the first electrostatic image with a toner of a first color to create a first toner image, preferably uniformly recharging the photoconductive member, imagewise exposing the charged member creating a second electrostatic image, developing the second electrostatic image by the application of toner of a second color to the exposed areas. The process can be repeated for any number of colors. The multicolor image is then transferred in a single step to a receiving sheet. The second and subsequent development steps are carried out by a magnetic brush developing device employing hard magnetic carrier particles that are tumbled through a development zone which tumbling does not adversely affect the prior toner images. Preferably the hard magnetic carrier particles have a coercivity of at least 100 gauss when magnetically saturated, but more preferably a coercivity of at least 1000 gauss when magnetically saturated.

    摘要: An LED printhead includes an optical mask overlying the LED's to balance light outputs therefrom. The transmission density of the mask is adjusted for each LED in accordance with its respective light output to adjust same so that the light outputs from all LED's are the same. The mask comprises a UV fadeable dye whose transmission density is adjusted with a UV laser or other light source while monitoring the light output from the respective LED. The transmission density of the mask may be adjusted by a UV light source provided on the printhead during periods of nonuse of the printhead or the printhead may be removed from the recording apparatus for adjustment.
