摘要： Embodiments of the present disclosure provide a method for estimating usage of a print substance. The method comprises receiving a plurality of pixels of a page to be printed, and generating, for one of the plurality of pixels, a look-up address based on (i) pixel bits of the one of the plurality of pixels, and (ii) pixel bits of one or more other pixels proximal to the one of the plurality of pixels. The method further comprises estimating an amount of print substance deposited on the page at a location associated with the one of the plurality of pixels based on reference to a print substance amount in a table of print substance amounts, wherein the reference to the print substance amount in the table is made using the look-up address.

摘要： A method and apparatus for handshaking using a 2-wire protocol is described. An electronic component may be divided into blocks, with the blocks performing one or more functions. The blocks may be in series with one another to form a pipeline. The blocks may use interface circuitry to transfer information upstream from or downstream to another block. The interface circuitry uses the 2-wire handshaking for the transfer including a transmit readiness wire configured to carry a signal indicative of readiness of the upstream circuit to output data and a receive readiness wire configured to carry a signal indicative of readiness of the downstream circuit to receive the data.

摘要： A device for adjusting the timing of at least one edge of an output pulse created in response to a reference pulse is disclosed. Such a device may include a first memory circuit having two or more first memory cells and a second memory circuit also having two or more second memory cells. The first memory circuit may be configured to periodically sample the reference pulse at the rising edges of a first sample clock while the second memory circuit may be configured to periodically sample the reference pulse at the falling edges of the first sample clock. A combinatorial logic circuit may also be included to produce the output pulse having at least one adjusted edge based on a set of timing instructions and timing information provided by the first and/or second memory circuits.

摘要： An image forming apparatus performs periodic line based image transformation in order to correct for irregularities in a mirror and for mechanical disturbances that may occur during the rotation of the mirror. The irregularities of the mirror and the mechanical disturbances that occur during the rotation of the mirror may be measured at installation or may be measured during an operation of the image formation apparatus. The characteristics of the mirror are stored as configuration data, which is referenced by a direction of rotation. The image forming apparatus adjusts image data according to the configuration data. The adjustment may occur through data manipulation in stored image data. Alternatively, the adjustment may occur through the control of a pixel rate used to modulate the image data into a transmitted laser beam. The image data may be received by a host device or the image data may be generated by a scanner.
