Abstract: A method of operating a printer analyzes a printed test pattern in a low-contrast printing configuration. The method includes forming a printed test pattern having a plurality of rows of negative marks on an image receiving member, each negative mark in the plurality of rows of negative marks being surrounded by ink from at least a portion of the plurality of inkjets. The method further includes generating scanned image data of the test pattern and identifying a plurality of locations in the cross-process direction for the negative marks in at least one row of negative marks in the scanned image data of the test pattern.

Abstract: An inkjet printer is provided that is configured to store a plurality of pieces of gap information respectively corresponding to a plurality of examined sections discretely arranged along a head moving direction on a recording sheet, each of the plurality of examined sections including a corresponding one portion of top portions and bottom portions on the recording sheet, and calculate interpolation gap information to be interpolated over a whole width in the head moving direction of at least one of a plurality of segments, each of which has a width in the head moving direction defined by two adjacent sections of the plurality of examined sections, based on the stored gap information.

Abstract: A method for reducing horizontal banding in a printed image printed with an inkjet print engine includes printing on a print media sheet a first test patch with a first inkjet printhead being moved by the printhead carrier in a first print direction; printing on a print media sheet a second test patch with the first inkjet printhead being moved by the printhead carrier in a second print direction; determining a first characteristic of the first test patch; determining a second characteristic of the second test patch; comparing the first characteristic of the first test patch with the second characteristic of the second test patch; and selecting, based on the comparing, an initial print direction of the first inkjet printhead for a first printing pass that reduces horizontal banding in generating the printed image.

Abstract: A cleaning device for shoe soles is disclosed. The cleaning device provides a surface having a plurality of bristles designed to engage the sole of a shoe. The bristles are arranged such that one or more groups of bristles are reciprocated over the length of the surface to dislodge and remove debris on the shoe sole. The debris removed from the shoe sole is also directed away from the bristles and surface into a receptacle for later removal. Thus, the cleaning device provides for effortless removal of debris from shoe soles while cleaning any debris dislodged by the bristles.

Abstract: An apparatus for cleaning footwear includes a chamber having a toe area, a heel area, two opposed side areas and a bottom area. In one aspect, the apparatus includes two linearly reciprocating side brushes, wherein one side brush is disposed in each side area, each side brush being movable along a first direction. In another aspect, the apparatus includes two side brushes, the side brushes being linearly movable toward each other and way from each other.

Abstract: In a printer that allows dual-way printing, a test pattern is formed to adjust the print timing with a high accuracy, or more concretely to eliminate a deviation of dots created in the course of a main scan in a backward direction from dots created in the course of the main scan in a forward direction. The test pattern is based on a normal dither matrix. The test pattern includes a plurality of dots that are regularly arranged both in a main scanning direction and in a sub-scanning direction. When the test pattern is printed at an appropriate timing, it is observed as a substantially homogeneous state without unevenness of the density. In case that the dot print timing is deviated, on the other hand, a deviation in dot interval causes unevenness of the density. The deviation of the dot print timing is accurately detected, based on the presence or the non-presence of such unevenness of the density.

Abstract: The present invention provides a cleaning device for shoe soles. The cleaning device includes a housing in which a brush rack assembly and an oscillating device for oscillating the brush rack assembly are housed. The brush rack assembly includes a plurality of brush rods situated in a spaced manner. Each of the brush rods defines a rod from which a multitude of bristles extend. The cleaning device also includes a vacuum assembly for catching and removing dirt removed from the shoe soles. Specifically, the vacuum assembly includes a vacuum device and a reservoir. The brush rack assembly is supported in the reservoir and the reservoir defines a port which extends through the housing and to which the vacuum device is connectable.

Abstract: A clothes washer includes a wash tub in which an agitator is mounted. The agitator includes a blade member which oscillates clockwise and counterclockwise about a vertical axis, a reciprocable member which oscillates with the blade member while reciprocating up-and-down, and a shoe cleaning device mounted on the reciprocable member for oscillation and vertical reciprocation therewith. The shoe cleaning device includes a circular plate carrying a plurality of brushes.

Abstract: Washing device for cleaning a cylinder of a printing machine includes a brush roller formed with bristles and rotatably driven about an axis, the brush roller cooperatively engaging the cylinder, a device for feeding washing fluid to the bristles for self-cleaning the bristles, and a deflection element disposed in a rotational region of the bristles, fixed in position relative to the brush roller and extending along the length of the brush roller, the bristles yieldingly brushing against the deflection element as the brush roller is rotated so as to be bent temporarily and subsequently returned to a straight extended position thereof, the deflection element being formed as a distributor pipe connected to the feeding devices and having outlet openings formed therein for directing the washing fluid radially towards the axis of the brush roller.

Abstract: The present invention relates to shoe sole cleaner 1 comprising a power section 2 and a brush section 3. The brush section is essentially planelike and it includes brush rods. The power section and the brush section are placed at a distance from each other. The power section is provided with a fluid power supply. The brush section includes a vibrating member such as a piston in a piston and cylinder combination. The fluid power supply is connected to the vibrating member by a fluid transmission means such as a pipe 5. The vibrating member is in contact with the brush rods and by means of the vibrating member the brush rods are made to move in a desired back and forth motion. The shoe sole cleaner according to the invention is low in construction so that it fits in the place of ordinary doormats. The cleaner can be extended simply by connecting serveral similar brush sections together as a large shoe sole cleaner.

Abstract: A shoe cleaning apparatus for household use includes a horizontal rotary brush to clean a toe portion of the sole of a shoe, a reciprocating brush to clean a heel portion of the shoe, and a vertical oscillating brush to clean side portions of the shoe. All the brushes are driven by a single motor which, along with the brushes, is mounted in a housing. A shoe rest bar extends across the housing between the rotary brush and the reciprocating brush. A user of the apparatus places an instep of the shoe on his foot on the shoe rest bar and pivots about the bar to vary the degree of engagement between portions of the shoe and the rotary and reciprocating brushes. The rotary brush includes baffles which cooperate with the rotary brush to create an airflow to carry away material removed from the shoe to a filter bag.

Abstract: An automatic washing machine for shoes which has a water tub incorporating a dehydrating tub which is provided with inner brushes which are mounted with shoes and vertically moved, outer brushes which are arranged to come in contact with external surface of shoes and vertically moved in opposite directions to the inner brushes, and driving means for driving the inner and outer brushes; the water tub is provided with a discharging mechanism to discharge water as required from the water tub and with a lifting head section which opens and closes an opening of the water tub at a position above the water tub and the head section is provided with an air nozzle for drying washed shoes to blow air for drying into the dehydrating tub while the opening of the water tub is closed by the head section.
