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.

摘要： An example of apparatus including an attachment assembly to mate a liquid supply with a reservoir is provided. The apparatus includes an outlet port disposed on the attachment assembly, wherein the outlet port is to dispense liquid from the liquid supply to a receiving port of the reservoir. The apparatus includes a main vent port disposed on the attachment assembly, wherein the main vent port is to receive air from the reservoir as the liquid enters the reservoir. The apparatus includes a plug disposed on the attachment assembly, wherein the plug is to seal a secondary vent when the attachment assembly is mated with the reservoir, and wherein the plug is to break a seal with the secondary vent prior to detachment of the attachment assembly to recover the liquid from the attachment assembly.

摘要： A wiping assembly includes an endless belt and a plurality of rollers about which the belt is mounted. A first roller mounts a first end of the belt adjacent a first end of a belt zone while a second roller is adjacent at an opposite, second end of the belt zone. A third roller mounts a second end of the belt and is located at an intermediate position along a first orientation between the respective first and second ends of the belt zone. The third roller is translatable along the first orientation while the first roller and the second roller are non-translatable along the first orientation. The third roller is biased toward the first end of the belt zone to apply tension on the belt.

摘要： A wiping assembly includes a pair of guide elements located at opposite ends of a headland region of a fluid ejection assembly to extend in a second orientation generally perpendicular to a first orientation through which the opposite ends extend. Each guide element includes at least one first portion and a second portion. The at least one first portion selectively receives biased releasable engagement from a non-wiping portion of a wiping element extending along the first orientation to cause a wiping portion of the wiping element to be in generally parallel relation to, and spaced apart from, the headland region. The second portion causes the non-wiping portion to no longer be in biased releasable engagement against the guide element and causes the wiping portion to be biased in wiping relation against the headland region.
