Abstract: Data describing an image to be printed on a print medium is transferred to an ink jet print head. The print head has n number of nozzles in a vertical array for sequentially ejecting vertical columns of ink droplets onto the print medium as the print head scans horizontally across the print medium. The vertical columns of ink droplets ejected during a single pass of the print head collectively comprise a swath of the image. As the data is received from a data source, a required memory space is determined which would accommodate a portion of the data describing a swath of the image to be printed using all n of the nozzles. A current available capacity of a memory device is determined and the amount of image data received from the host is determined. A portion of the data that describes a swath of the image to be printed using a number m of the nozzles is transferred to the memory device. The number m depends on the minimum of the ratio of current available capacity of the memory device to the required memory space needed to accommodate data required to print a swath using all n of the nozzles and the ratio of the image data received from the host to the amount of image data required to print a swath using all n of the nozzles. The portion of the data that describes the swath of the image to be printed using the m number of the nozzles is transferred from the memory device to the print head. The swath of the image is then printed on the print medium using the m number of the nozzles.

Abstract: A clock circuit includes an oscillator for generating a reference frequency signal, and a spread spectrum clock generator cooperating with the oscillator for generating a spread spectrum clock output signal having a fundamental frequency and reduced amplitude EMI spectral components at harmonics of the fundamental frequency. The spread spectrum clock generator preferably includes a clock pulse generator for generating a series of clock pulses, and a spread spectrum modulator for frequency modulating the clock pulse generator to broaden and flatten amplitudes of EMI spectral components which would otherwise be produced by the clock pulse generator. The spread spectrum modulator frequency modulates the clock pulses with specific profiles of frequency deviation versus the period of the profile. Electronic devices including the spread spectrum clock circuit and associated method are also disclosed.

Abstract: Electrical interfaces, addressing schemes, and command protocols allow for communications with memory modules in computing devices such as imaging and printing devices. Memory modules may be assigned an address through a set of discrete voltages. One, multiple, or all of the memory modules may be addressed with a single command, which may be an increment counter command, a write command, a punch out bit field, or a cryptographic command. The commands may be transmitted using a broadcast scheme or a split transaction scheme. The status of the memory modules may be determined by sampling a single signal that may be at a low, high, or intermediate voltage level.

Abstract: A method implemented by a processor of a printer for reducing consumables usage based on job size includes entering different settings for an n-up printing mode in the printer based on job size such that a job size of one page will be printed 1-up, or on a full page, by the printer, a job size of two and three pages will be printed 2-up, or on a half page, by the printer, and a job size of four pages will printed 4-up, or on a quarter page, by the printer and/or entering a threshold setting for a duplex printing mode in the printer based on job size such that a job size below the threshold will be printed in a simplex mode whereas job size at or above the threshold will be printed in a duplex mode. The method also includes enabling user selection of n-up setting or threshold setting for jobs of predetermined size.

Abstract: A boot validation system and method may be used in a computer system to validate boot code before allowing the computer system to execute the boot code. In particular, a secure hash algorithm may be used to compute a hash value of the boot code and the computed hash value may be compared to a preprogrammed hash value stored in a secure non-volatile device. If the hash values match the boot code may be validated and the system may then be allowed to execute the boot code. Once the boot code is validated, the boot code may be executed to validate other code (e.g., firmware) in the computer system. In an exemplary embodiment, the boot validation system and method may be used in an imaging device, such as a printer.
