摘要： A cartridge of the type used with a printer is provided for supplying liquid to the printer. The cartridge includes a container that has first through sixth walls and a partition in the form of an inner wall that substantially divides the container into first and second compartments. The partition extends from the third wall to near the fourth wall to form a communication gap between the partition and the fourth wall. The container also has a first opening in the first compartment for allowing air to enter, and a second opening in the first compartment for interfacing with the printer's print head. A stranded material is disposed in the first compartment so that it extends along the first partition to a location between the end of the first partition and the fourth wall. A foam material is disposed in and substantially fills the remainder of the first compartment. The stranded material functions to regulate the internal pressure of the cartridge by selectively providing a low resistance path for air to pass from the first compartment, through the stranded material and the gap, and into the second compartment. This allows the cartridge to supply ink to the print head while keeping the pressure in the cartridge, and thus the vacuum in the print head, substantially constant.

摘要： A refill apparatus for refilling a liquid for a printer includes a printer cartridge housing, a liquid refill bottle and an adapter piece to convert the printer cartridge housing. The printer cartridge housing has an interior compartment and a print head (22) to deliver the liquid to the computer printer. The refill bottle (102) contains the liquid and has a septum (118) covering an opening to deliver the liquid from the refill bottle (102) to the print head in the printer cartridge housing. The adapter piece is placed in the interior compartment of the printer cartridge housing for converting the printer cartridge housing to be connectable with the refill bottle. The adapter piece includes a base (146), a seat (148), a foot (158) and plumbing. The seat (148) is coupled to the base and adapted to connect with the refill bottle (102) of liquid. The foot is coupled to the base and adapted to connect with the printer cartridge housing. The plumbing in the base is coupled to both the seat and the foot to deliver liquid from the refill bottle to the printer cartridge housing, and is also connected with the seat to deliver air to the refill bottle of liquid. The refill bottle is connected to the printer cartridge housing by the adapter piece, and the liquid is delivered from the refill bottle by the plumbing in the adapter piece.

摘要： A drop detection apparatus has a thermosensitive substrate (12) for receiving drops of ink and providing a signal representative of a change in the temperature in the thermosensitive substrate which caused by the ink drops deposited on the thermosensitive substrate. The thermosensitive substrate (12) is made from a pyroelectric material, such as, for example, polyvinylidene fluoride (PVDF) and lead zirconium titanate (PLZT). As a result, a drop detection apparatus (10) has a substantially simplified structure for detecting drops of ink ejected from large numbers of jets. Furthermore, since a drop detection apparatus relies on the temperature difference between the thermosensitive substrate and the drop of ink which is substantially small in size, the drop detection apparatus can be made substantially small in size, therefore suitable for a small sized ink jet apparatus.

摘要： A gas assisted liquid jet apparatus, suitable for use in ink jet printers, includes a transducer housing having a plurality of ink passages and is designed to be used with solid or hot melt ink. The apparatus operates with a compressed air source to provide a laminar air flow through an orifice from where ink is ejected. As a result, ink ligaments and droplets uniformly accelerate toward the printing medium, and the high speed laminar flow reduces friction at the orifice, thus reducing the formation of ink ligaments or satellite droplets. The apparatus may be made by attaching different layered members together. This improves the efficiency and ease of fabrication of multiple array liquid jet apparatus. Because of the layered structure, ink passages and air chambers each may be placed in a selected layered member or in more than one layered member. The location of the ink passages in the same layer or structure, such as the transducer housing, as a heater provides improved heating capabilities. The location of the ink passages in the transducer housing also minimizes the overall width of the apparatus.
摘要翻译：适用于喷墨打印机的气体辅助液体喷射装置包括具有多个墨水通道的换能器壳体，并被设计成与固体或热熔体墨水一起使用。该设备利用压缩空气源进行操作，以提供通过喷射墨水的孔口的层流气流。结果，油墨韧带和液滴均匀地朝着打印介质加速，并且高速层流减小了孔口处的摩擦力，从而减少油墨韧带或卫星液滴的形成。该装置可以通过将不同的分层部件附接在一起而制成。这提高了多阵列液体喷射装置的制造的效率和容易性。由于层状结构，墨水通道和空气室各自可以放置在选定的分层构件中或多个分层构件中。相同层或结构中的油墨通道（例如换能器壳体）作为加热器的位置提供了改进的加热能力。墨水通道在换能器壳体中的位置也使装置的总体宽度最小化。

摘要： UV-blocking hot melt ink jet inks for printing on flexible and other media. A UV-blocking hot melt ink jet ink for flexo-graphic plating comprises a wax, a plasticizer, a UV blocker, and a dye. Such an ink is flexible and durable, gives good printing quality, and is also removable from the flexo plate substrates during the wash out cycle of the flexo-plating process. Another UV-blocking hot melt ink jet ink for printing on silk screens comprises a wax, a fatty acid, a UV blocker, and a dye. Such an ink is readily removable from the silk screen without harming the screen.

摘要： This invention is a printer and a method for printing hot melt ink in which an ink jet (10) is surrounded by an enclosure (60), and including a heater (30) for heating the air within the enclosure (60). The enclosure (60) has an opening so that the heated air can be directed towards a medium (99) for heating the medium (99) prior to ejecting droplets of hot melt ink onto the medium. The ink droplets cool and solidify into a shape having a low contact angle.

摘要： A method of halftoning over a region of output pixels by defining large halftone cells (12) corresponding to regions of contiguous pixels (22) and partitioning the larger halftone cells into smaller halftone cells (24) is disclosed. The number of levels of gray determined by the number of pixels within the larger halftone cell while resolution is defined by the size of the smaller halftone cells within the larger halftone cells. A predetermined level of gray determines the number of pixels to darken within the larger halftone cell, and the pixels are darkened within the smaller halftone cell according to a spot function. The larger halftone cells are partitioned into smaller halftone cells such that the larger halftone cell has exactly one center smaller halftone cell.

摘要： A printer (10) stores print image data in memory (56) as the print image data is used by a print engine (12) to print an image in accordance with the print image data. In one embodiment, separate data buses (17, 46) and separate processors (40, 50) are used to transfer the print image data to the print engine and the memory so that the transfer operations can occur independently and in parallel. In another aspect, the print image data is compressed before it is stored in the memory. In yet another aspect, an overrun condition is detected when the transfer of data to the memory falls behind the transfer of data to the print engine. During the overrun condition, transfer of data to the memory is suspended until after the page has been printed.
摘要翻译：当印刷图像数据被打印引擎（12）使用以根据打印图像数据打印图像时，打印机（10）将打印图像数据存储在存储器（56）中。在一个实施例中，分离的数据总线（17,46）和分开的处理器（40,50）用于将打印图像数据传送到打印引擎和存储器，使得传送操作可以独立地并行地进行。在另一方面，打印图像数据在存储在存储器中之前被压缩。在另一方面，当将数据传送到存储器落在数据传送到打印引擎之后，检测到溢出条件。在超载条件下，暂停数据到内存的传输，直到打印页面为止。
