摘要： A catcher design is provided wherein vacuum channels are added to both sides of the catcher to remove ink from the face of the catcher and from the eyelid seal. An additional fluid port on the catcher allows the additional vacuum channels to maintain an increased level of vacuum. A restriction on the catcher line balances the fluid flow between the catcher and the additional vacuum channels. A scoop can be machined into the catch pan to remove fluid from below the catcher face. A manifold can be used to maintain a vacuum source for the catcher throat and the additional channels, while pulling the unprinted ink back to the fluid system. Finally, a wider eyelid seal can allow purge fluid used during shutdown to clear the channels.

摘要： A laminated structure utilizes differential adhesive to achieve high adhesion to a wicking material and low adhesion where removal is desired. The low profile wicking pad is useful in any technology where it is desirable to control excess moisture with a passive device. The wicking device is particularly useful in the field of continuous ink jet printing systems, where the low profile of the device is desirable and the cost reduction makes disposability of the device a reality. In ink jet printing systems, the wicking device improves ink jet printhead performance via ink mist and ink drip elimination.

摘要： A technique for sealing a printhead of an ink jet printer system on startup, opening the seal to print, and opening further on an arbitrary path for service, is provided for by the present invention. The ink jet printhead has an ink drop generator, a catcher located adjacent to the ink drop generator, and a catcher pan located below the catcher. An eyelid seals ink within the printhead on startup of the printer system. An actuator mechanism transmits movement to the eyelid along a predetermined path, having multiple positions for the eyelid. The eyelid is moved between open and closed positions by means of a dc motor. The open position is defined by the actuator means contacting a print position stop. Shifting the position of the print position stop allows the eyelid to open to a service position.

摘要： An inkjet printer has a catcher and eyelid seal for sealing against the catcher during startup and shutdown. A wicking means is provided for removing excess ink from a fluid channel of the catcher having an associated catcher plate, in an area of the eyelid seal. The wicking means is positioned in an area at a bottom surface of the fluid channel, without bridging a height of the fluid channel, above the catcher plate, and in close proximity to the eyelid seal, while maintaining a consistent pressure at an entrance to the fluid channel.

摘要： The method and equipment for detangling individual jets in an ink jet print station utilizes a reservoir containing fluid and a printhead. The printhead has a drop generator, an orifice structure connected to the drop generator for forming numerous jets, a catcher connected to the drop generator; and a charge device secured to the catcher. A fluid supply system is connected between the printhead and the reservoir. A controller and numerous actuators are connected to the drop generator, and adapted to vibrate the drop generator. A fluid pump is connected to the fluid supply line, is operated by the controller, and is adapted to raise the pressure on the drop generator to at least an operating pressure and lower the pressure on the drop generator to a minimal pressure to prevent entanglement of the jets.

摘要： An ink jet printer for depositing ink drops from a plurality of jet drop streams on a print receiving medium includes a print head which generates a plurality of jet drop streams, such streams being positioned in at least one row. The drops are selectively charged and, thereafter, pass adjacent a deflection electrode which extends parallel to and to one side of the row of jet drop streams. A drop deflecting electrical potential is applied to the deflection electrode to produce a drop deflection field which directs the drops into print and catch trajectories. A catcher extends parallel to the row of jet drop streams and on the opposite side of the row from the deflection electrode. The catcher is positioned directly opposite the deflection electrode and receives drops in the catch trajectories, while permitting the drops in the print trajectories to strike the print receiving medium. The catcher includes a plurality of internal catcher cavities and defines a substantially vertical drop catching surface and a drop ingesting slot beneath the drop catching surface. Each of the cavities communicates with an associated portion of the drop ingesting slot. The catcher may include a substantially electrically non-conductive body portion which defines the drop catching surface.

摘要： The use of the lowest all catch voltage for deflecting the charged droplets onto the catcher surface enhances the reliability of the startup sequence for ink jet printers. Going from a state where all of the droplets are hitting in the eyelid seal and catch pan assembly to a state where all of the droplets are deflected and caught on the catcher face will help eliminate the possibility of splatter on the charge plate electrodes and/or the charge short detect level circuitry, ink on top of the eyelid seal, and wicking of ink out of the eyelid.

摘要： A method is provided for transitioning from a lower pressure state to a final operating pressure state. Initially, an eyelid is used to divert ink into a fluid channel associated with the catcher assembly. Pressure of the ink is reduced to a low ink pressure level that will allow the ink to be removed by the fluid channel. Pressure of the ink is increased to at least one incremental step, before reaching a final ink operating pressure. A charge voltage is turned on to deflect ink into catch in a time interval short enough to prevent ink backup between the eyelid and the catcher assembly.

摘要： An ink supply system for supplying ink through the print head of an ink jet printer includes a pump arrangement supplying ink to the print head from a supply tank and, further, plural ink return lines connected between the pump outlet and the pump inlet. Each of the ink return lines includes a flow restriction, with the flow restriction in each line providing a fluid flow impedance which differs from the impedances provided by the other flow restrictions. A valve arrangement controls the connection of the pump outlet to a selected one of the ink return lines, such that the flow rate of ink through the ink supply line to the print head is effectively controlled.
