摘要： A printhead having a number of single-dimensional memristor banks is described. The printhead includes a number of nozzles to deposit an amount of fluid onto a print medium. Each nozzle includes a firing chamber to hold the amount of fluid, an opening to dispense the amount of fluid onto the print medium, and an ejector to eject the amount of fluid through the opening. The printhead also includes a number of single-dimensional memristor banks. Each memristor bank includes a number of memristors arranged in a single dimension and a number of serially-connected de-multiplexers to selectively activate a target memristor of the memristor bank. The number of serially-connected de-multiplexers is equal to the number of memristors and an output of at least one de-multiplexer is an input into a subsequent de-multiplexer.

摘要： In an example, a method of managing a nozzle condition test on a printhead includes instructing a printhead to perform impedance measurements on a plurality of nozzles in a first set of nozzles. The method also includes retrieving from the printhead, an impedance measurement result corresponding with each nozzle, where each impedance measurement result indicates a nozzle condition of its corresponding nozzle.

摘要： A print head for use with a printer. The print head includes an input that receives data or commands associated with printing from the printer. A memory component of the print head is connected in communication with the input and is configured to bi-directionally communicate information to the printer via the input. For example, the memory component may be soldered to a circuit of a print head and connected to a data line normally used to communicate print data to the print head. In this manner, the print head may hold configuration information in the memory module for easy upgrades without an additional dedicated communication line. Also, printers may be upgraded, and print heads retrofit, with the memory component without installation of a dedicated input or communication line.

摘要： An inkjet printer comprises a body housing a print engine configured to transport and print upon print media; a cover pivotally mounted relative to the body and able to be pivoted to form a guide which can guide print media to the print engine for printing; a support configured to support the print media guided to the print engine and pivotally mounted relative to the cover so that the support can be retracted between the cover and the body; and a stepper motor for driving a sheet feed roller and a paper transport. The stepper motor drives the paper transport when operated in a forward direction, and drives the sheet feed roller when operated in the reverse direction.

摘要： Provided is a printer controller for controlling a pagewidth printhead. The controller includes an interface for receiving an image having a bi-level black data layer compressed in an Edge Delta and Runlength (EDRL) compression format and a continuous tone (contone) CMYK data layer. Also included is an EDRL expander and a Joint Photographic Experts Group (JPEG) decoder unit for expanding the image by simultaneously decompressing the two data layers in parallel, as well as a halftoner and compositor unit for halftoning the contone CMYK data layer into bi-level CMYK data layer and compositing the bi-level black data layer over the bi-level CMYK data layer to form a composited bi-level CMYK image. The controller further includes a processor and memory arrangement configured to control the interface, the expander and decoder unit, and the halftoner and compositor unit, and further configured to transmit the composited bi-level CMYK image to a memory buffer of the pagewidth printer via a printhead interface.
