摘要:
An apparatus is used with an ink jet print head in an ink jet printer. The apparatus includes a print head protector that surrounds a print head. A substantially continuous slot is provided along a perimeter of the bracket and a filter is located in the substantially continuous slot. An inlet in fluid communication with the substantially continuous slot enables a positive pressure air supply to be coupled to the inlet. The air entering the inlet flows through the filter in the slot and the filtered air flows outwardly away from the print head.

An image forming device includes marking material dispensers for disposing an image on an imaging drum surface. The image forming device further includes plural particle removal devices comprising first and second particle removal devices coupled to a vacuum source. The first particle removal device includes a first vacuum port positioned as close as possible to an included image transfer site. The second particle removal device includes a second vacuum port positioned as close as possible to the marking material dispensers. The first and second vacuum ports are positioned proximate to the imaging drum surface to provide respective first and second air flows.

System and method for encapsulating edges of a paper in digital printing systems. A spray applicator can include a set of stationary sprayers with spray nozzles, a set of transfer rollers and an inkjet print head. The stationary sprayers can be positioned at both marginal ends of the paper. The stationary sprayers apply the fluid through the spray nozzles at edges of the moving paper to encapsulate the edges of the paper such that loose paper fibers and debris are bound to the paper. The fluid can be applied when the transfer rollers can pass the moving paper through a printer or printing press. Thus, the system can protect various subsystems of the printer or printing press against contamination due to the loose paper fibers and debris.

A maintenance method for an ink jet imaging device comprises ejecting drops from a plurality of ink jets to successively form a plurality of images on the image receiver. Inter-image intervals between the ejection of drops to form one image in the plurality of images and the ejection of drops to form a successive image in the plurality of images are detected. A plurality of drops is ejected from at least a portion of the ink jets in the plurality of ink jets during at least one detected inter-image interval. The plurality of ejected drops having at least one drop ejecting characteristic selected from: a drop mass for the plurality of drops being greater than a standard drop mass; a drop ejecting frequency for the plurality of drops being lower than a standard drop ejecting frequency; and a substantially sequential drop ejecting pattern for the plurality of drops.

Embodiments herein comprise a compact dust abatement apparatus that includes at least one manifold shaped to fit next to a belt or drum of a printing engine, at least one blower/fan positioned within the manifold, and at least one air duct connected to the manifold. The manifold has a vacuum opening adjacent the belt or drum and an exit opening where the air duct connects to the manifold. The blower is positioned inside the manifold, between the vacuum opening and the exit opening, such that the blower draws air and particles from the vacuum opening toward the exit opening. Thus, the blower creates a vacuum at the vacuum opening. The air duct directs air and particles from the manifold to a location away from the sensitive components. The inclusion of the blower inside the vacuum manifold provides for compactness without sacrificing performance.
