Problems solved by technology
An idle fluid ejector in ejector array 12A may misfire due to fluid drying on printhead 10 adjacent to the idle fluid ejector
Additionally, fluid injectors in injector array 12A that are too close to the sidewall of well 16 may cause fluid to be splashed from the target area if injector array 12A is used during a pass over well 16
[0009] Using a conventional printhead 10 can be an efficient method of filling the wells 16 of a microwell plate, however, many passes of the printhead 10 may be required to achieve large fluid dispensing volumes

Embodiment Construction
[0035] Compared to conventional inkjet printing devices, the disclosed embodiments provide a unique fluid ejection head for dispensing a predetermined amount of fluid into a target area, as set forth in more detail below. One application of the fluid ejection head is to use the digital dispensing device 20 to deposit fluid onto a substrate, such as a microwell plate 18 ( image 3 ) in well 16. For the purposes of this disclosure, the substrate described herein is a microwell plate 18 . However, the devices and methods described herein may be applied to deposit fluids onto any suitable substrate including, but not limited to, glass slides, circuit boards, and the like.
[0036] According to an embodiment of the present disclosure, when the tray 32 containing the microwell plate 18 is moved past the digital dispensing device 20 by the translation mechanism 34 in the Y direction indicated by arrow 36, the fluid ejection head 38 ( Figure 5 ) moves in the X direction as shown by...

A digital dispensing device and method for ejecting one or more fluids into a target area of a substrate, and a fluid ejection head. The digital dispensing device includes: (A) a fluid ejection head for the digital dispensing device, the fluid ejection head having one or more fluid ejector arrays thereon; (B) a fluid ejection head translation device for moving the fluid ejection head over a target area of the substrate in a first direction, where the array of one or more fluid ejectors on the fluid ejection head is oriented parallel to the first direction; and (C) a control device for activating one or more fluid injectors in the one or more fluid injector arrays when the one or more fluid injectors intersect a target area of the substrate.
Description
technical field [0001] The present disclosure relates to methods for precisely dispensing one or more fluids onto or into precise regions of a substrate to perform analysis on samples confined to precise regions of a substrate or to build layers of materials in predetermined regions of a substrate The device and method thereof, in particular to a fluid ejection head, a digital distribution device and a distribution method. Background technique [0002] Devices such as inkjet devices can dispense very small ink droplets (often measured in picoliters) onto a substrate. For inkjet printing applications, the volume of ink deposited is a relatively low quantity, and the volume is not as important as other factors such as color matching and print quality. Typical inkjet printers are limited to depositing about 2 μL / cm 2 to about 3μL / cm 2 . A typical inkjet printhead may have one or more fluid supply vias each associated with a different colored jetting head, where the jetting ...
