- pressure control is provided by a vacuum source 30 such as a mechanical pump that applies a vacuum to the headspace 9 over the ink 12 in the reservoir 11.

Channels 44 control stray ink on the nozzle plate that could affect nozzle performance. For example, during ink jetting, ink may end up collecting on the nozzle plate. Over time, ink can form puddles which cause printing errors. For example, puddles near the edge of a nozzle opening can effect the trajectory, velocity or volume of the ejected drops. Also, a puddle could become large enough so that it drips onto printing substrate 20 causing an extraneous mark.

Fig. 2 is a perspective view of a nozzle plate, whileFig. 2A is an expanded view of region A inFig. 2 . -
Figs. 3-3C are cross-sectional views of a nozzle, taken along 3-3 ofFig.2A , illustrating drop ejection. - Referring to
Fig. 1 , aninkjet apparatus 10 includes areservoir 11 containing a supply ofink 12 and apassage 13 leading from thereservoir 11 to apressure chamber 14. Anactuator 15, e.g., a piezoelectric transducer, covers thepressure chamber 14. The actuator is operable to force ink from thepressure chamber 14 through apassage 16 leading to a nozzle opening 17 in annozzle plate 18, causing a drop ofink 19 to be ejected from thenozzle 17 toward asubstrate 20. During operation, theink jet apparatus 10 and thesubstrate 20 can be moved relative to one another. For example, the substrate can be a continuous web that is moved betweenrolls nozzles 17 innozzle plate 18, a desired image is produced onsubstrate 20. - The inkjet apparatus also controls the operating pressure at the ink meniscus proximate the nozzle openings when the system is not ejecting drops. Variations in meniscus pressure can cause variation in drop volume or velocity which can lead to printing errors and weeping. In the embodiment illustrated, pressure control is provided by a
vacuum source 30 such as a mechanical pump that applies a vacuum to theheadspace 9 over theink 12 in thereservoir 11. The vacuum is communicated through the ink to the nozzle opening 17 to prevent ink from weeping through the nozzle opening by force of gravity. Acontroller 32, e.g. a computer controller, monitors the vacuum over the ink in thereservoir 11 and adjusts thesource 30 to maintain a desired vacuum in the reservoir. In other embodiments, a vacuum source is provided by arranging the ink reservoir below the nozzle openings to create a vacuum proximate the nozzle openings. An ink level monitor (not shown) detects the level of ink, which falls as ink is consumed during a printing operation and thus increases the vacuum at the nozzles. A controller monitors the ink level and refills the reservoir from a bulk container when ink falls below a desired level to maintain vacuum within a desired operation range. In other embodiments, in which the reservoir is located far enough below the nozzles that the vacuum of the meniscus overcomes the capillary force in the nozzle, the ink can be pressurized to maintain a meniscus proximate the nozzle openings. In embodiments, the vacuum is maintained at about 0.5 to about 10 inches of water. - Referring to
Figs. 2-2A ,nozzle plate portion 40 includes a plurality ofnozzle openings 42 formed in a substantiallyplanar substrate 41. Also formed insubstrate 41 proximate eachnozzle opening 42 is a cleaning structure in the form of achannel 44.Channels 44 control stray ink on the nozzle plate that could affect nozzle performance. For example, during ink jetting, ink may end up collecting on the nozzle plate. Over time, ink can form puddles which cause printing errors. For example, puddles near the edge of a nozzle opening can effect the trajectory, velocity or volume of the ejected drops. Also, a puddle could become large enough so that it drips ontoprinting substrate 20 causing an extraneous mark. The puddle could also protrude far enough off thenozzle plate 40 surface that theprinting substrate 20 comes into contact with it, causing a smear on theprinting substrate 20. Thechannels 44 collect, localize and direct waste ink. Referring particularly toFig. 2A ,channels 44 completely surround each nozzle opening 42 that is centered onplatform area 43.Channels 44 are connected byradial channels channels 44, forming a network of connected channels that direct and hold stray fluid on the nozzle plate. - Referring particularly to
Fig. 3 , anozzle opening 42 with anadjacent channel 44 is illustrated before drop ejection. Referring toFigs. 3A and 3B ,waste ink 38 deposits onplatform area 43 and is drawn intochannel 44 by capillary forces. Referring toFig. 3C ,waste ink 38 is contained and distributed aboutnozzle opening 42 bychannel 44. Upon encounteringradial channels nozzle opening 42 and into the network of connected channels that direct and hold stray fluid (seeFig. 2 ). When the nozzle plate is oriented vertically, waste ink moves through the network of channels under the influence of both gravity and capillary action, macroscopically in a single direction. When the nozzle plate is oriented horizontally, a vacuum source or wicking material can be used to remove ink from the channels. - The spacing, size and orientation of the channels are selected to control waste ink. In embodiments, the spacing, S, from an edge of the channel to an edge of the nozzle opening is between about 20 % of a nozzle width, WN, or more, e.g., 30 % or more, and about five times the nozzle width or less, e.g., three times the nozzle width or less. The width, WC, and depth, D, of the channel is selected to prevent excessive pooling of ink on the nozzle surface and to allow fluid to be drawn into the space defined by the channel and retained by capillary forces. In embodiments, the channel width is between about twice the nozzle width or less and about 10 % of the nozzle width or more. In particular embodiments, the channel width, WC, is, e.g., about 100 microns or less, e.g., 5-20 microns, and the channel depth, D, is, e.g., about 2-10 microns or more, e.g., 50 microns. In embodiments, the nozzle width WN is, e.g., about 200 microns or less, e.g., 25-100 microns and the spacing S from the nozzle opening to the edge of the channel is, e.g., 40 microns or greater, e.g., 100 microns. In embodiments, the nozzle pitch is about 25 nozzles/inch or more, e.g., about 300 nozzles/inch, the ink drop volume is about 1 to 70 pL and the fluid is pressurized by a piezoelectric actuator. In embodiments, the jetting fluid has a viscosity of about 1 to 40 centipoise and a surface tension of about 20-50 dynes/cm. In embodiments, the jetting fluid is ink. In embodiments, the channels can include a wicking material and/or a nonwetting coating (e.g., TEFLON® fluoropolymer) can be applied to the nozzle plate surface between the nozzle and the channel. The channel network can also be in communication with a vacuum source (not shown). Waste ink can be returned to the main ink supply or to a separate suction system. In embodiments, the orientation of the channel is circular. In other embodiments, the orientation of the channel is sinuous.
- The channels and/or the nozzle opening in any of the above described embodiments can be formed by machining, electroforming, laser ablation, and chemical or plasma etching. The channels can also be formed by molding, e.g., injection molded plastic channels. In embodiments, the channel, nozzle opening, and pressure chamber are formed in a common body. The body can be a metal, carbon or an etchable material such as silicon material, e.g., silicon or silicon dioxide. Forming printhead components using etching techniques is further described in

For example, the deposited droplets may be a UV or other radiation curable material or other material, for example, chemical or biological fluids, capable of being delivered as drops. For example, the apparatus described could be part of a precision dispensing system. The actuator can be an electromechanical or thermal actuator. The cleaning structures can be combined with a manual or automatic washing and wiping system in which a cleaning fluid is applied to the nozzle plate and wiped clean. The cleaning structures can collect cleaning fluid and debris rather than jetted waste ink.
