摘要： Disclosed is a hot air circulating system (4) for printing press, which comprises a number of primary air blowers (41) and a number of primary heating devices (42) connected at air suction openings of the primary air blowers. The technical gist of the present solution is as follows: air blowing openings of the primary air blowers (41) are in communication with printing presses (1) through primary air blowing passages (5), primary air suction passages (6) are connected between the primary heating devices (42) and the printing presses (1), and the primary air suction passages (6) are provided thereon with a number of air discharging passages. Through replacing the method in the prior art that increases hot air's temperature with an effective and convenient one that adjusts and increases the amount of circulating air, the hot air circulating system for printing press in the present application improves drying effects on thin films, which effectively reduces losses of thermal energy, thus making the whole equipment more energy-saving; meanwhile, the utilization of large flows of air circulation effectively improves drying effects on thin films, such that printing presses are not required to be added with cooling rollers. In this manner, thin films are prevented from being deformed due to temperature shock, thus improving the rate of finished products; furthermore, the air discharging amount is also effectively decreased, thus reducing pollution caused to production workshops.

摘要： A printer is disclosed herein. The printer has a printhead having a plurality of ink nozzles for ejecting ink, a servicing mechanism for capturing the ejected ink from the ink nozzles, to service the printhead, and a control device coupled to the printhead and the servicing mechanism for regulating the servicing. As part of the regulation, the control device continues feeding a substrate towards the printhead during an idle period. The idle period of the printhead can be a duration when printing on the substrate is suspended. Further, the control device regulates ejection of ink from the ink nozzles towards the substrate during the idle period and operates the servicing mechanism during the idle period. In an example, the servicing mechanism captures the ink before the ink reaches the substrate.

摘要： A printing system including a print engine, a drying module, and a heating module. The print engine applies printing fluid on media. The drying module dries the printing fluid and provides dried printing fluid. The heating module applies thermal energy to the dried printing fluid and transitions the dried printing fluid to a cured printing fluid that has improved durability versus the dried printing fluid.

摘要： In a printer in which an inkjet head is mounted in a carriage, which is movable in a direction intersecting with a conveyance direction of a recording medium, and ink is ejected from the inkjet head to record an image onto the recording medium, there has been a problem in that the recording medium is charged due to friction and separation at the time of conveyance of the recording medium, and ink mist is attracted to a portion charged to have an unexpected pattern to be recorded. In view of this problem, static electricity generated on the recording medium is removed by providing the carriage with an ionizer for generating a positive ion and an ionizer for generating a negative ion and generating the ions at the time of scanning of the carriage. The static electricity can be removed efficiently by arranging on the carriage the ionizers for generating the ions of both polarities, namely, the positive ions and the negative ions.

摘要： An image forming apparatus includes a substrate receiving member, a fluid applicator unit, and an air recirculator assembly. The substrate receiving member may selectively receive a substrate. The fluid applicator unit may selectively eject a first set of drops to the substrate received by the substrate receiving member in a print mode and a second set of drops in a maintenance mode. The air recirculater assembly may direct air to form an air barrier across the print zone to redirect at least one of aerosol and particulates from crossing through the air barrier and onto the substrate, to filter the at least one of the aerosol and particulates to form filtered air, and to form the air barrier with the filtered air.
