Abstract: Disclosed are FIFO type methods, systems and apparatus for electronically registering image data relative to a rastering device or other marking device. According to an exemplary method, a FIFO type data queuing configuration is provided, where the length of data memory segments associated with the FIFO are a function of a spatial profile associated with the ink jet rastering device.

Abstract: Provided is a recording medium conveying mechanism including an endless center conveying belt and endless side conveying belts, the endless center conveying belt and the endless side conveying belts being looped over a driving roller to be driven by a motor, a driven roller and a tension roller. The center conveying belt is positioned in a center in a width direction of a recording medium to be conveyed, and the side conveying belts are positioned on opposite sides in a width direction of the center conveying belt, respectively. The center conveying belt includes a material with a high elastic modulus while the side conveying belts include a material with a low elastic modulus, and a biasing member for providing a tension to the center conveying belt and the side conveying belts is provided on a shaft of the tension roller.

Abstract: The present invention provides a recording apparatus including recording heads each including a plurality of nozzle arrays that are arranged so as to overlap, wherein the width with which the overlapping portions of the recording heads for colors that are simultaneously used with a relatively high frequency overlap in an intersecting direction that intersects an array direction of nozzles is smaller than the width with which the overlapping portions of the recording heads for colors that are simultaneously used with a relatively low frequency overlap in the intersecting direction.

Abstract: A method for controlling an image forming apparatus including a head having a nozzle for discharging a liquid droplet; a sub-tank for temporarily storing the liquid supplied to the head; a main tank for storing the liquid; a pump capable of forwardly sending the liquid from the main tank to the sub-tank and reversely sending the liquid from the sub-tank to the main tank; and a sensor for sensing a pressure in the sub-tank is provided. In the method, before sending the liquid forwardly or reversely to achieve a target negative pressure in the sub-tank, a pressure sensing function of the sensor is checked by sending the liquid with the pressure in the sub-tank being at a negative pressure range in which a meniscus of the liquid is maintained. When the pressure sensing function is determined abnormal, a control is performed not to send the liquid by the pump.

Abstract: Certain embodiments provide an image forming apparatus including: a paper feed section; an image forming section; a transport mechanism; a sheet sensor which detects leading and trailing edges of the sheet; a sensor power source which supplies electric power to the sheet sensor; a detecting section which specifies the position of the sheet based on the position of the sheet sensor in a transport path and a detection output from the sheet sensor; and a driving control section which generates a timing signal indicating a first detection period when a leading edge of the sheet is detected and a timing signal indicting a second detection period when a trailing edge of the sheet is detected, turns on the sensor power source in the first detection period and the second detection period, and turns off the sensor power source in a period different from the respective detection periods.

Abstract: Provided is a fluid ejecting apparatus including: a fluid ejecting head; a receiving member which is linear; a support member which supports the receiving member; a support member movement unit which moves the support member between a first position and a second position so that the receiving member is located at a receiving position capable of receiving the fluid ejected from the nozzles at the first position, and the receiving member is located at a retreat position deviating from the receiving position at the second position; and a tensile force changing unit which is capable of changing tensile force changing unit changes the tensile force applied to the receiving member from a first tensile force to a second tensile force smaller than the first tensile force when the support member movement unit moves the support member from the second position to the first position.

Abstract: A small footprint drum inkjet printer having a print head consisting of a number of print head arrays; a substrate carrier preferably in the form of a drum with vacuum orifices therein, a substrate loading cassette capable of movement, relative to the drum, in at least one direction; a substrate unloading cassette capable of movement, relative to the drum, in at least one direction, and a curing radiation source having a reflector which extends along the drum surface.

Abstract: A sub tank receives ink supplied from a main tank through a supply path. The sub tank includes a supply chamber that causes the ink to move toward a nozzle, and a pressure control chamber connected to the supply chamber through a connection part that can open/close. The pressure control chamber includes a pressure resistor that reduces the speed of the ink when the ink pressure rises in the supply path, and a volume changing member that is provided on at least a side of the connection part with respect to the pressure resistor in the ink flow direction, so that pressure in the pressure control chamber can be reduced by reducing the ink speed and increasing the volume of the pressure control chamber.

Abstract: A printing paper seasoning apparatus includes: a loading table on which a plurality of sheets of printing paper are stacked and loaded; a ceiling plate which is disposed above the loading table so as to oppose the loading table for covering over an upper side of a stack of the printing paper loaded on the loading table; an air blowing device which blows air from a side face side into a paper accommodating region formed between the loading table and the ceiling plate which are arranged so as to oppose each other; a side plate arranged in a side face portion of the paper accommodating region; and an exhaust section including openings formed in the side plate, wherein an opening ratio of the exhaust section varies in a vertical direction of the paper accommodating region in such a manner that the opening ratio on a lower side of the exhaust section is smaller than the opening ratio on an upper side of the exhaust section.
