摘要： A print head pump assembly has a piezo element plate having an array of piezoelectric elements, a channel plate having an array of channel regions corresponding to the array of piezoelectric elements, and a valve plate having an array of reed valve pairs corresponding to the array of channel regions. A print head assembly has at least one ink reservoir, an upper routing plate to receive ink from the ink reservoir, a lower routing plate to direct ink out of the print head, and a pump assembly to draw ink from the upper routing plate and deliver ink to the lower routing plate using piezoelectric diaphragms. A method of delivering ink to a print substrate includes providing ink to a low-pressure reservoir of a print head, drawing ink out of the low-pressure reservoir through an upper routing plate using a pump assembly internal to the print head, and pumping ink out of the print head through a lower routing plate using the pump assembly, such that the drawing and pumping processes continuously alternate.

摘要： A printhead wiper assembly includes an elongated member having a first and second wiper, a linkage, and an actuator. The linkage includes a clutch that enables the elongated member to move to a plurality of positions in response to the actuator activating a plurality of times. The sequence of positions enables first wiper and then the other wiper to contact the printhead face to remove purged ink from the face.

摘要： A system and method for adjusting the registration of an image applied to recording media in a printer. The timing of the ejection of ink from an inkjet printhead of the printer is adjusted to maintain proper registration of a first side image to a second side image for duplex printing and y registration within a second side image printing from a first color print unit, such as magenta, to a last print unit, such as black. The location of a leading edge of the first side image deposited on a continuous web of recording media is identified and the timing of ink ejection from printhead nozzles is adjusted to align the second side image to the first side image. Adjustment of the timing of ink ejection reduces or eliminates observable registration errors.

摘要： A leveling and spreading system has been developed that enables the speed and position of the web to be determined from a sensor on a first roller. In a duplex print process, the first roller also reduces a temperature of the media web and an ink image printed in the first side print operation to within a first predetermined temperature range. A second roller modulates the temperature of the media web and ink ejected onto the media web immediately before the web enters the leveling and spreading system to within a second predetermined temperature range to enable uniformity of the ink and web temperatures for spreading the ink in a nip formed with a third roller.

摘要： A method for adjusting the tension of a continuous web of recording media in a printing system. The method includes identifying a tension in the continuous web and adjusting the tension in response to the amount of ink being deposited on the recording media. An offset tension value is determined, stored in memory, and used by a controller to adjust the velocity or tension of the continuous web moving through the printing system to improve the printing of images.

摘要： A system that avoids any stopping or reversing of the web direction in a continuous feed printer, instead maintaining consistent process speed, only requiring a slowing and speeding up of the web to cycle through the PR belt seam. This is done by forming a web loop and then immediately flattening the loop after passage of the seam through the transfer zone that includes two transfer BTR rolls with alternating transfer operations, but simultaneous transfer for short periods. Two vacuum assist rolls, one located between the two bias transfer rolls controls the formation of the web loop. A pair of nip forming rolls upstream of the first transfer station and a second vacuum assist roll downstream of the second transfer station control the size of the loop.
