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： An alignment apparatus and method is provided for attaching and aligning components of an ink jet printhead of a continuous ink jet printer. First and second bonding surfaces are provided on first and second components, respectively, of the ink jet printhead. The first and second components are then aligned and attached. The attaching can be accomplished by applying an adhesive, which may also incorporate a chemical accelerator, or by distributing an adhesive from a central region of the bonding surfaces to create an adhesive bond between the first and second bonding surfaces.

摘要： The present invention provides for an improvement in the removal of fluid from an ink jet printhead. A branched structure having multiple groups of branches creates a flow geometry, with each group of branches having a connecting trunk. The fluid flow is then able to be directed from each plurality of branches down the connecting trunk. Pressure drops at the branching nodes are minimized by directing the flow from the combined branches down the connected trunk. Expansion losses at the branching nodes are minimized by funneling down the flow at the branching nodes, with the trunk having a narrower channel than the combination of the joined branches.

摘要： A printing system using multiple printheads maintains color consistency between the printheads by printing a first color patch (102) with a first color with a plurality of printheads (30) at a first pressure and with a first pixel fill coverage. A second color patch (104) is printed with the first color with the plurality of printheads at a second pressure with the first pixel fill coverage. The print density of the first patch and the second patch is measured for each of the plurality of printheads and the print density for each of the plurality of printheads is compared. A pressure for each of the plurality of printheads is adjusted to compensate for differences in density between the first patch and the second patch for each of the printheads.

摘要： A printhead includes a jetting module, a catcher, a drop deflection mechanism, and a capping mechanism. The jetting module includes an array of nozzles and is operable to form liquid drops from liquid emitted through the nozzles of the nozzle array. The catcher collects some of the liquid drops. The drop deflection mechanism deflects the liquid drops such that some of the liquid drops contact the catcher while other liquid drops are allowed to contact a print media. The capping mechanism includes a capping member located between the nozzle array of the jetting module and the drop deflection mechanism. The capping member has a first position covering the nozzle array and a second position removed from the nozzle array.

摘要： A system and method are provided for cleaning the printhead of a continuous ink jet printing system. A cleaning fluid is introduced and used to flush ink residues and debris from the interior of the drop generator, the exterior of the orifice plate, the charge plate face and the catcher face. This system and method removes dried ink residues and other debris and deposits by providing a cleaning fluid with a low surface tension to dissolve or flush away the unwanted material from the orifices. This is particularly advantageous in that the flushing and rinsing is accomplished without mechanical contact which could abrade or damage the orifices.
