Description

APPARATUS HAVING FLUID INTERCONNECTS

Background

[0001] Imaging systems, such as printers, copiers, etc., may be used to form markings on a physical medium, such as text, images, etc. In some examples, imaging systems may form markings on the physical medium by performing a print job. A print job can include forming markings such as text and/or images by transferring a print material (e.g., ink, toner, etc.) to the physical medium.

Detailed Description

[0009] Imaging devices may include a supply of a print material located in a print material supply cartridge. As used herein, the term “print material” refers to a substance which can be transported through and/or utilized by an imaging device. In some examples, print material can be, for instance, a material that when applied to a medium, can form representation(s) (e.g., text, images models, etc.) on the medium during a print job. In some examples, print material can be, for instance, ink, three- dimensional print material, cleaning fluids, fluids for chemical analysis, fluids to be included during transportation of the imaging device (e.g., shipping to a customer), etc.

[0010] The print material can be deposited onto a physical medium. As used herein, the term “imaging device” refers to any hardware device with functionalities to physically produce representation(s) (e.g., text, images, models, etc.) on the medium, in some examples, a “medium” may include paper, photopolymers, plastics, composite, metal, wood, or the like.

[0011] The print material supply cartridge including the print material may interface with the imaging device and include a supply of the print material such that the print material may be drawn from the print material supply cartridge as the imaging device creates the images on the print medium. As used herein, the term “print material supply cartridge” refers to a container, a tank, and/or a similar vessel to store a supply of the print material for use by the imaging device. In some examples, the print material supply cartridge can provide print material directly to a print head of the imaging device. In some examples, the print material supply cartridge can supply print material to a fluid interconnect which can provide print material to a print head of the imaging device.

[0012] A print material supply cartridge may be filled, replaced, etc. In some examples, the print material supply cartridge may supply print material to an imaging device and be removed, in some examples, the print material supply cartridge may be interfaced with the imaging device and reside in the imaging device to provide print material when appropriate.

[0013] In some instances, there can be residual print material during the transfer of print material from the print materia! supply cartridge to the imaging device. As used herein, the term “residual print material” refers to print material that is leftover, spilled, dripped, coated, filmed, or sprayed during the transferring of print material, in such an instance, the residual print materia! can be transferred to undesired locations, such as users, space surrounding the imaging device, imaging device parts, etc. Additionally, residual print material can build up within the imaging device and/or contaminate imaging device parts, which may cause damage to the imaging device.

[0014] An apparatus having fluid interconnects, according to the disclosure, can allow for residual print material to be absorbed during and/or after print material transfer. Accordingly, a fluid interconnect having a shutter assembly including a number of print material reservoirs can reduce print material from being transferred to an undesired location within or surrounding the imaging device.

[0015] Figure 1 is a view of an example of an imaging device 100 including an apparatus 102 having fluid interconnects 104-1, 104-2, 104-3, . . ., 104-N consistent with the disclosure. Each of the fluid interconnects 104-1, 104-2, 104-3, . . ., 104-N can be coupled to a print material supply cartridge 106 having a different color. For example, a first fluid interconnect can be coupled to an print material supply cartridge having cyan print material, a second fluid interconnect can be coupled to a print material supply cartridge having magenta print material, a third fluid interconnect can be coupled to a print material supply cartridge having yellow print material, and a fourth fluid interconnect can be coupled to a print material supply cartridge having black print material. However, examples of the disclosure are not so limited. As described herein, each of the fluid interconnects 104-1, 104-2, 104-3, . . ., 104-N can transfer print material from a print material supply cartridge 106 it is coupled to.

[0016] As illustrated in Figure 1, the apparatus 102 can be located within the imaging device 100 such that the apparatus 102 is easily accessible. For example, the apparatus 102 can be accessed upon removal of an access panel 105 disposed on a surface of the imaging device 100. However, examples of the disclosure are not so limited. This can allow for the print material supply cartridge 106 to be attached to one of the fluid interconnects 104-1, 104-2, 104-3, . . ., 104-N so that the print material supply cartridge 106 interfaces with the imaging device 100.

[0017] As described herein, each of the fluid interconnects 104-1, 104-2, 104- 3, . . ., 104-N can include print material reservoirs (e.g,, as illustrated in Figures 2-7) to absorb and wipe away residual print material during and post print material transfer, reducing the amount of print material being transferred to an undesired location within and/or on the imaging device 100. For example, a plurality of print material reservoirs can be positioned within each of the fluid interconnects 104-1, 104-2, 104-3, . . ., 104-N and as print material is transferred from the print material supply cartridge 106 to the imaging device 100, via one of the fluid interconnects 104-1, 104-2, 104-3, . . ., 104-N, the plurality of print material reservoirs can absorb and/or wipe away any residual print material.

[0018] Figure 2 is a section view of an example of an apparatus 202 having fluid interconnects 204-1, 204-2, 204-3, . . 204-N consistent with the disclosure.

As described herein (e.g., in connection with Figurel), each of the fluid interconnects 204-1, 204-2, 204-3, . . 204-N can correspond to a print material supply cartridge having a different color.

[0019] As illustrated in Figure 2, fluid interconnects 204-1, 204-2, 204-3, . . ., 204-N can include shutter assemblies 208-1, 208-2, 208-3, . . ., 208-N. As used herein, the term “shutter assembly” refers to a physical structure that contains parts of the of fluid interconnect and absorbs and/or wipes away residual fluid material as the shutter assembly travels in a vertical direction. For example, each of the shutter assemblies 208-1, 208-2, 208-3, . . ., 208-N can include one of the first print material reservoirs 212-1, 212-2, 212-3, . . ., 212-N to absorb and/or wipe away residual print material during and post print material transfer (e.g., transfer of print materia! from the print material supply cartridge and to the imaging device via a fluid interconnect needle). Additionally, each of the fluid interconnects 204-1, 204-2, 204-3, . . ., 204-N can include one of the third print material reservoirs 214-1, 214-2, 214-3, . . ., 214-N to absorb residual print material during and post print material transfer. Thus, the first print material reservoirs 212-1, 212-2, 212-3, . . ., 212-N and third print material reservoirs 214-1, 214-2, 214-3, . . ., 214-N can reduce the amount of print material being transferred to an undesired location and/or building up within the imaging device.

[0020] Each of the first print material reservoirs 212-1, 212-2, 212-3, . . ., 212- N can be a rigid material, such as a porous plastic material. Each of the third print material reservoirs 214-1, 214-2, 214-3, . . ., 214-N can be a non-woven material, such as a felt material. While not illustrated in Figure 2, each of the shutter assemblies 208-1, 208-2, 208-3, . . ., 208-N can also include a second print material reservoir (e.g., second print material reservoir 316 illustrated in Figure 3) positioned adjacent to the print material reservoirs 212-1, 212-2, 212-3, . . ., 212-N.

[0021] Figure 3 is a section view of an example of a system 320 having a fluid interconnect 304 attached to a print materia! supply cartridge 306 consistent with the disclosure. The fluid interconnect 304 can include a shutter assembly 308 having a first print material reservoir 312 to absorb residual print material during print material transfer, and a second print material reservoir 316 positioned adjacent to the first print material reservoir 312 to absorb residual print material from the first print material reservoir 312.

[0022] As illustrated in Figure 3, the fluid interconnect 304 can include a needle assembly 309 having a fluid interconnect needle 318 to transfer print material from the print material supply cartridge 306 to an imaging device (e.g., imaging device 100 illustrated in Figure 1). Upon attachment of the print material supply cartridge 306, the fluid interconnect needle 318 can become inserted into the print material supply cartridge 306. The print material supply cartridge 306 can apply pressure against a spring 322 of the shutter assembly 308 to cause the shutter assembly 308 to travel vertically along the fluid interconnect needle 318 and switch to a compressed position (e.g., a down position as illustrated in Figure 3). Additionally, when the print material supply cartridge 306 is attached, the fluid interconnect needle 318 can become exposed (e.g., not surrounded) by the compressed shutter assembly 308.

[0023] The fluid interconnect needle 318 can push through a septum 323 to create a fluid connection allowing the transfer of print material. As used herein, the term “septum” refers to a dividing membrane between a first area and a second area. For example, the septum 323 can include a dividing membrane between an outer area of the print material supply cartridge 306 and an inner area of the print material supply cartridge 306, where the outer area makes contact with the fluid interconnect 304 and the inner area contains the print material to be transferred. [0024] The fluid interconnect needle 318 can pierce the septum 323 of the print material supply cartridge 306 to enter the print material supply cartridge 306 and press a sealing member 324, such as a sealing ball, away from the septum 323, This can allow printing material to flow (e.g., transfer) from the print material supply cartridge 306 into an opening (e.g., opening 536 illustrated in Figure 5) of the fluid interconnect needle 318. The fluid interconnect needle 318 can transfer the print material to the imaging device. Upon detachment of the print material supply cartridge 306, the sealing member 324 can be pushed, via a spring 326, back into place against the septum 323 forming a seal.

[0025] As illustrated in Figure 3, the shutter assembly 308 can include the spring 322, where the print material supply cartridge 306 is attached to the fluid interconnect 304, the print material supply cartridge 306 applies pressure against the spring 322 causing the shutter assembly 308 to travel in a vertical direction as illustrated in Figure 3. In other words, the shutter assembly 308 travels vertically (e.g,, in a up/down direction as illustrated in Figure 3) along the fluid interconnect needle 318 when the print material supply cartridge 306 is attached to the fluid interconnect 304. A first print material reservoir 312 and a second print material reservoir 316 positioned within the shutter assembly 308 can absorb and/or wipe away residual print material left on the fluid interconnect needle 318 as the shutter assembly 308 travels vertically along the fluid interconnect needle 318. This may reduce the amount of print material being transferred to an undesired location and/or building up within and/or on the imaging device.

[0028] As illustrated in Figure 3, the first print material reservoir 312 and second print material reservoir 316 can be positioned adjacent to each other within the shutter assembly 308 and can form a ring surrounding the fluid interconnect needle 318 allowing the first print material reservoir 312 and second print material reservoir 316 to absorb and/or wipe away residual print materia! from the fluid interconnect needle 318. For example, the second print material reservoir 316 can be located below the first print material reservoir 312 so that the second print material reservoir 316 can absorb residua! print material absorbed by the first print material reservoir 312. in some examples, the second print material reservoir 316 may absorb residual print materia! from the first print material reservoir 312 so that the first print material reservoir 312 does not become over saturated with residual print material. In some examples, the first print material reservoir 312 may absorb residual print material from the second print material reservoir 316 so that the first print material reservoir 316 does not become over saturated with residual print material.

[0027] In some examples, the first print material reservoir 312 can surround a port (e.g., the tip of the fluid interconnect needle having a hole to transfer print material) of the fluid interconnect needle. Thus, there may be space (e.g., as illustrated in Figures 4 and 6) between the first print material reservoir 312 and the fluid interconnect needle 318 and print material may enter the space between the first print material reservoir 312 and the fluid interconnect needle 318. In such an example, the second print material reservoir 316 may absorb some/all of the print material that enters (e.g., collects in) the space between the first print material reservoir 312 and the fluid interconnect needle 318. The first print material reservoir 312 can be a rigid material, such as a porous plastic material to allow the shutter assembly 308 to travel vertically along the fluid interconnect needle 318 and to prevent material (e.g., fibers) from entering the fluid interconnect needle 318. The second ink reservoir 316 can be a non-woven material, such as a felt material to wipe away and/or absorb print material from the fluid interconnect needle 318.

[0028] As illustrated in Figure 3, the fluid interconnect 304 can also include a third print material reservoir 314 positioned on an inner surface of the fluid interconnect 304. The third print material reservoir 314 may be adjacent to the shutter assembly 308 when the shutter assembly 308 is in a non-compressed position (e.g., when the print material supply cartridge 306 is not attached to the fluid interconnect 304). The third print material reservoir 314 can be a sheet-like non- woven material (e.g., a sheet-like felt material) to absorb residual print material that travels along the shutter assembly 308 during print material transfer. For example, the third print material reservoir 314 can absorb residual print material that is not absorbed or wiped away by the first print materia! reservoir 312 and second print material reservoir 316 during print material transfer.

[0029] As illustrated in Figure 3, the fluid interconnect can include a capillary element 328 positioned adjacent to the third print material reservoir 314. The capillary element 328 can enable the transfer of print material to the third print material reservoir 314. For example, the capillary element 328 can convey the print material from the first print material reservoir 312 and the second print material reservoir 316 to the third print material reservoir 314. The capillary element 328 can be a wicking material, such as a polyester material treated to absorb and wick away (e.g., draw away) print material from the first print material reservoir 312 and the second print material reservoir 316.

[0030] For example, as the shutter element 308 becomes compressed into a down position as illustrated in Figure 3, by the print material supply cartridge 306, the first print material reservoir 312 and the second print material reservoir 316 may come in contact with the capillary element 328. Upon contact, the capillary element 328 can absorb and/or wick away print material from the first print material reservoir 312 and the second print material reservoir 316 and convey the residual print material to the third print material reservoir 314.

[0031] Figure 4 is a section view of an example of a fluid interconnect 404 consistent with the disclosure. As described above, the fluid interconnect 404 can include a needle assembly 409 including a fluid interconnect needle 418 and a shutter assembly 408. The shutter assembly 408 can include a first print material reservoir 412 to absorb residual print material during print material transfer and a second print material reservoir 416, positioned adjacent to the first print material reservoir 412, to absorb residual print material from the first ink reservoir 412 and to remove residual print material from the fluid interconnect needle 418.

[0032] As illustrated in Figure 4, the fluid interconnect 404 can include a longitudinal axis, the shutter assembly 408 can include a longitudinal axis, and the fluid interconnect needle 418 can include the longitudinal axis. The longitudinal axis of the shutter assembly 408 can be coaxial (e.g,, share a common axis) with the longitudinal axis of the fluid interconnect 404. The longitudinal axis of the fluid interconnect needle 418 can be coaxial with the longitudinal axis of the fluid interconnect 404. Similarly, the longitudinal axis of the shutter assembly 408 can be coaxial with the longitudinal axis of the fluid interconnect needle 418. In other words, the longitudinal axes of the fluid interconnect 404, shutter assembly 408, and the fluid interconnect needle 418, respectively, can be coaxial.

[0033] As illustrated in Figure 4, the fluid interconnect 404 can include a fluid interconnect needle 418 to transfer print material from a print material supply cartridge. Upon attachment of the print material supply cartridge, the fluid interconnect needle 418 can become inserted into the print material supply cartridge. The print material supply cartridge can apply pressure against a spring 422 of the shutter assembly 408 to cause the shutter assembly 408 to travel vertically along the fluid interconnect needle 418. As described above (e.g., in connection with Figure 3), the fluid interconnect needle 418 can pierce a septum of the print material supply cartridge to enter the print material supply cartridge and press a sealing member away from the septum. This can allow print material to flow from the print material supply cartridge into an opening of the fluid interconnect needle 418 and be transferred to the imaging device.

[0034] As illustrated in Figure 4, the first print material reservoir 412 (e.g., a porous plastic print material reservoir) and the second print material reservoir 416 (e.g., a felt print material reservoir) can be positioned adjacent to each other. For example, the second print material reservoir 416 can be located below the first print material reservoir 412 so that the second print material reservoir 416 can absorb residual print material from the first print material reservoir 412. [0035] As illustrated in Figure 4, the fluid interconnect 404 can also include a third print material reservoir 414 (e.g., a sheet-like felt print material reservoir) positioned on an inner surface of the fluid interconnect 404 and adjacent to the needle assembly 409. The third print material reservoir 414 can absorb residual print material that is not absorbed or wiped away by the first print material reservoir 412 and second print material reservoir 416 during print material transfer.

[0036] Figure 5 is a section view of an example of a system 540 having a fluid interconnect 504 consistent with the disclosure. As described above, the fluid interconnect can include a needle assembly 509 including a fluid interconnect needle 518 and a shutter assembly 508. The shutter assembly 508 can include a first print material reservoir 512 to absorb residual print material during ink transfer and a second print material reservoir 516 positioned adjacent to the first print material reservoir 512 to absorb residual print material from the first print material reservoir 512 and remove residual print material from the fluid interconnect needle 518. in some examples, the first print material reservoir 512 can absorb residual print material from the second print material reservoir 516.

[0037] As illustrated in Figure 5, the fluid interconnect can include a fluid interconnect needle 518 to transfer print material from a print material supply cartridge. As described above, upon attachment of the print material supply cartridge 506, the fluid interconnect needle can become inserted into the print material supply cartridge 506. Print material can enter the fluid interconnect needle 518, via opening 536, and fluid interconnect needle 518 can transfer the print material to the imaging device.

[0038] As iiiustrated in Figure 5, the shutter assembly 508 can include a spring 522, When the print material supply cartridge 506 is attached to the fluid interconnect 504, the print material supply cartridge 506 may apply pressure against the spring 522 causing the shutter assembly 508 to travel in a vertical direction. [0039] As described above, the shutter assembly 508 can include the first print material reservoir 512 (e.g., a porous plastic print material reservoir), a second print material reservoir 516 (e.g., a felt print material reservoir). Additionally, the fluid interconnect 504 can include a third print material reservoir 514 (e.g., a sheet-like felt print material reservoir). The first print material reservoir 512 may absorb residual print materia! from the fluid interconnect needle 518 and/or from the second print material reservoir 516. The second print material reservoir 516 may absorb residual print materia! from the first print materia! reservoir so that the first print material reservoir does not become over saturated with residual print material and from the fluid interconnect needle 518. The third print material reservoir 514 may absorb residual print materia! that is not absorbed or wiped away by the first print material reservoir 512 and second print material reservoir 516 during print material transfer. [0040] As illustrated in Figure 5, the fluid interconnect 504 can include a capillary element 528 positioned adjacent to the third print materia! reservoir 514. As described above, the capillary element 528 can enable the transfer of print material to the third print material reservoir 514. The capillary element 528 can be a wicking material, such as a polyester materia! treated to absorb and wick away (e.g., draw away) print material from the print material ink reservoir 512 and the second print material reservoir 516.

[0041] For example, as the shutter element 508 becomes compressed into a down position as illustrated in Figure 5, the first print material reservoir 512 and the second print material reservoir 516 may come in contact with the capillary element 528. Upon contact, the capillary element 528 can absorb and/or wick away print materia! from the first print material reservoir 512 and the second print materia! reservoir 516 and convey the residua! print material to the third print material reservoir 514.

[0042] A capillary head (e.g., capillary pressure) of the capillary element 528 may increase as the print material travels deeper into the fluid interconnect 504. For example, an increased capillary head can enable the capillary element 528 to draw print material from the first print material reservoir 512 prior to the first print material reservoir 512 becoming saturated with print material. Additionally, an increased capillary head can prevent the saturation of the first print materia! reservoir 512 and the second print material reservoir 516 until the third print material reservoir 514 is fully saturated. This may reduce the degree of ink exposure in a case where there is unintentional contact with the first print materia! reservoir 512 and/or the second print material reservoir 516.

[0043] Figure 6 is a section view of an example of a fluid interconnect 604 having a non~compressed shutter assembly 608 consistent with the disclosure. As described above, the fluid interconnect 604 can include a needle assembly 609 having a fluid interconnect needle 618 and a shutter assembly 608. The shutter assembly 608 can include a first print material reservoir 612 and a second print material reservoir 616 to absorb and/or wipe away residual print material from the first print materia! reservoir 612 to absorb residual print material during ink transfer.

A third print material reservoir 614 can also absorb residual print material that Is not absorbed or wiped away by the first print material reservoir 612 and second print materia! reservoir 616 during print material transfer [0044] As described above, the fluid interconnect can include a non- compressed shutter assembly 608 when a print material supply cartridge is not attached to the fluid interconnect 604. Similarly, the shutter assembly 608 can include a non-compressed spring 622 when a print materia! supply cartridge is not attached. A non-compressed shutter assembly 608 can provide physical support to the fluid interconnect needle 618 as the shutter assembly, when not compressed, surrounds the entire length of the fluid interconnect needle 618.

[0045] Figure 7 is a section view of an example of a fluid interconnect 704 having a compressed shutter assembly 708 consistent with the disclosure. As described above, the fluid interconnect 704 can include a needle assembly 709 including a fluid interconnect needle 718 and a shutter assembly 708. The shutter assembly 708 can Include a first print material reservoir 712 and a second print material reservoir 716 to absorb and/or wipe away residual print material during print materia! transfer.

[0046] As described above, the shutter assembly 708 can become compressed when a print material supply cartridge is attached to the fluid interconnect 704. For example, the print material supply cartridge can apply pressure against the spring 722 located within the shutter assembly 708 forcing the shutter assembly 708 to travel vertically (e.g., in a downward direction as illustrated in Figure 7) along the fluid interconnect needle 718, Similarly, when the print material supply cartridge is detached, the pressure applied by the print material supply cartridge is removed and the shutter assembly 708 can travel vertically (e.g., in an upward direction) and returns to a non-compressed position (e.g., an up position as illustrated in Figure 6).

[0047] As described above, the first print materia! reservoir 712 and the second print material reservoir 716 can surround the fluid interconnect needle 718. The first print material reservoir 712 and the second print material reservoir 716 can absorb residual print material left on the fluid interconnect needle 718 as the shutter assembly 708 travels vertically (e.g., upward/downward as illustrated in Figure 7) along the fluid interconnect needle 718. A third print material reservoir 714 can also absorb residual print material that is not absorbed or wiped away by the first print material reservoir 712 and second print material reservoir 716 during print material transfer. This may reduce the amount of print material being transferred to an undesired location and/or building up within the imaging device.
