摘要： In the ink jet printing system described in the specification, a hot melt ink jet printhead having two ink reservoirs is coupled through an ink supply line to a remote hot melt ink supply and a temperature controller is arranged to control the temperatures of the ink in the remote ink supply, the supply line, the ink reservoirs in the printhead and passages leading from the reservoirs to the ink jet orifices at selected temperature levels to inhibit high-temperature degradation of the ink while permitting the ink to be jetted at the desired jetting temperature. In addition, a pressure control system controls the pressure of the ink in the printhead at one or more selected levels to permit the printhead to be used at different orientations and to permit purging of air bubbles and contaminants from the orifice passageways and to supply a relatively high vacuum to a deaerator in the printhead to extract dissolved air from the ink. A check valve in the ink supply line permits the printhead to be positioned at different elevations with respect to the remote ink supply without causing any undesired flow of ink between the reservoir and the printhead.

摘要： In the representative ink supply system described in the specification, continuous circulation of ink in an ink jet head is accomplished by providing two reservoirs connected to each ink jet orifice through corresponding passages so that ink flows continuously from a high-level reservoir past the orifice to a low-level reservoir. The difference between the levels of ink in the reservoirs is maintained relatively constant by inertial pumping during reciprocal motion of the ink jet head or by pressure transfer of ink from one reservoir to the other reservoir. Cross-flow purging of air or debris from the ink jet head is effected by covering the ink jet orifices and applying air pressure to one reservoir to cause ink and any trapped air or debris to flow from the head to the other reservoir. A pump responsive to reciprocal motion of the ink jet head generates a positive air pressure which is applied during purging and a negative air pressure which is applied to a deaerator for removing dissolved air from the ink.

摘要： In the embodiment of the cleaning device described in the specification, a web of paper is movable past the orifice plate of an ink jet head from a supply roll to a take-up roll. The cleaning device has a movable front end portion with two pressure bars positioned to urge the web of paper against two portions of the orifice plate, one portion being in line with the orifices and the other below the orifices. The pressure bar supports are arranged so that the bar positioned in line with the orifices engages the web after the other bar has urged the web against the orifice plate. The cleaning device also collects ink ejected during purging of air from the system and may be positioned to prevent ejection of ink during an internal purging operation.

摘要： In the representative hot melt ink supply system described in the specification, a first hot melt ink supply reservoir maintains ink in molten condition during operation of the system and a second reservoir mounted with an ink jet head on a movable carriage communicates with the first reservoir through a flexible supply line. The ink in the supply line is normally kept in solid condition and, when a reduced level of ink is detected in the second reservoir, the supply line is heated to melt the ink in the line and a pump is actuated to transfer ink from the first reservoir to the second reservoir. To permit use of pigmented inks, each of the reservoirs is heated to provide a thermal gradient therein so as to maintain convective circulation of the ink. An ink circulation path is provided to cause convective circulation of pigmented ink in the ink jet head.

摘要： In the particular embodiment of an ink deaerator described in the specification, an elongated ink path leading to an ink jet head is formed between two permeable membranes. The membranes are backed by air plenums which contain support members to hold the membranes in position. Reduced pressure is applied to the plenums to extract dissolved air from the ink in the ink path. Increased pressure can also be applied to the plenums to eject ink from the ink jet head for purging. Within the ink jet head ink is circulated convectively from the orifice to the deaerating path even when the jet is not jetting ink.

摘要： In the representative embodiments of the invention described in the specification, an ink jet head has a series of aligned arrays of ink jet orifices arranged to project drops of different colored inks in sequence to the same location on a substrate during each scan of the ink jet head adjacent to the substrate. The spacing of the orifices in each aligned array and the speed of the ink jet head during the scanning are arranged so that all the ink drops applied at the same location on the substrate are applied in a time period of no more than about 100 milliseconds and preferably no more than 50 milliseconds. Moreover, to avoid banding the lines produced by successive scans of the head are interlaced so as to produce a periodic frequency of no more than about four lines per millimeter.
