Toners of the same color but with different characteristics are stored in the toner cartridges. For example, toners for high image quality (High Grade) with small particle diameter are stored in some toner cartridges and toners for low image quality (Low Grade) are stored in other toner cartridges. In this case, case, the mode of forming images using small particle diameter toner for high image quality using an image forming engine and the mode of forming images using a toner for low image quality using another image forming engine are executed by the image forming apparatus.

Provided is an imaging cartridge with a universal body sculpted to mate with the imaging cartridge-receiving cavity of a plurality of imaging machine models. The universal body of the imaging cartridge enables the cartridge to be used with imaging machines made by different manufacturers, and different imaging machine models made by a common manufacturer. A plurality of recesses is formed in the leading end of the imaging cartridge body that accepts protuberances in an imaging machine's cartridge-receiving cavity and enables the cartridge to mate with a plurality of printers.

This invention provides for a method of page expansion and printing of image data received from a computer. The method includes the steps of receiving a page description from the computer, the page having a bi-level black layer compressed in an EDRL (Edge Delta and Runlength) format and a continuous tone (“contone”) layer, and decompressing the respective layers in parallel. The method also includes the steps of halftoning the contone layer data to a bi-level data and compositing the bi-level black layer over the bi-level data to form an image, and transmitting the image data for printing to a pagewidth printhead arrangement. The method includes operating the printhead according to one of a low-speed nozzle firing mode and a high-speed firing mode, the low-speed firing mode having a firing rate half that of the high-speed firing mode.

The invention relates to a method of printing a compressed image having a bi-level black data layer and a continuous tone (contone) CMYK data layer. The method includes the steps of receiving the image from an image host, expanding the image by decompressing the two data layers in parallel, and halftoning the contone CMYK layer data into a bi-level CMYK data layer. The method also includes the steps of compositing the bi-level black layer over the bi-level CMYK layer to form a composited bi-level CMYK image, and finally printing the composited bi-level CMYK image with a pagewidth printhead onto a print medium.

An image forming apparatus includes a toner cartridge that is configured to be detachably attachable to a main body of the image forming apparatus and stores toner, a cartridge memory unit that is provided in the toner cartridge and stores information on the toner cartridge, an image forming unit that forms a toner image using toner supplied from the toner cartridge, a memory determining unit that determines whether the cartridge memory unit is in a normal state, a count unit that counts an amount of toner consumption consumed for the toner image formed by the image forming unit, and a life determination unit that determines the life of the toner cartridge corresponding to an amount of residual toner remaining in the toner cartridge, wherein the life determination unit shifts its mode between a first life-determination mode in which the life is determined on the basis of a count value of the count unit and a second life-determination mode in which the life is determined on the basis of the toner density of a toner image used as a patch image formed by the image forming unit, on the basis of the result of determination of the memory determining unit.

An inkjet printer includes a body defining a print media path along which print media can pass. A printhead assembly is arranged within the body and includes a printhead which is configured to print upon print media passing along the print media path. A print media feed arrangement is configured to feed the print media along the print media path. Printer controller circuitry is arranged in the body, and is operatively connected to the printhead assembly and print media feed arrangement to control a printing operation carried out by the printhead assembly. A print media input tray is pivotally mounted with respect to the body and can locate the print media in register with the print media path. A user interface is located on the body to enable a user to interface with the printer. The input tray is able to fold with respect to the body to thereby form a protective cover for the user interface.

A printer is provided for authenticating a replaceable ink cartridge. The printer includes a processor. The replaceable ink cartridge can be releasably coupled to the processor and includes a first integrated circuit (IC). A printhead is interfaced to the processor and is configured to print ink supplied from the ink cartridge. A second IC is interfaced to the processor and, together with the processor, can be used to authenticate the first IC and therefore the ink cartridge.
摘要:
A method for image processing data representing a page to be printed includes the step of respectively receiving, in a data processing apparatus, external to a printer, data representing a bi-level black layer and a contone layer of a page to be printed. In the data processing apparatus, a halftoning process is applied to data representing the contone layer to form a bi-level cyan, yellow, magenta, and black (CYMK) layer. In the data processing apparatus, a compositing process is applied to data representing the bi-level black layer to composite the bi-level black layer over the bi-level CYMK layer to form a bi-level CYMK image of the page to be printed. The data representing the halftoned and composited layers is compressed to generate compressed image data. The compressed image data is written to the printer. An expansion process is applied to the compressed image data in the printer to generate data representing the page to be printed. The page is printed with the printer.
