Abstract: A microfluidic delivery device and method of dispensing a fluid composition therefrom is provided. The microfluidic delivery device includes a housing electrically connectable with a power source; a cartridge releasably connectable with the housing; and a fan connected with the housing. The cartridge has a reservoir for containing a fluid composition and microfluidic die in fluid communication with the reservoir. The die is configured such that substantially all of the fluid composition exits the microfluidic die in a horizontal direction or downward direction relative to horizontal. The fan is configured to generate air flow that converges with and redirects the fluid composition dispensed from the microfluidic die in an upward direction relative to horizontal.

Abstract: A multi-color ink tank is adapted to replace individual different color ink tanks in a cavity of a given support structure. Elements on the body of the multi-color ink tank have configurations enabling compatibility with the support structure. The elements include empty opposite side portions of the body defining laterally spaced apart bottom openings that adapt the opposite side portions to seat in spaced slots in the cavity over keys therein and an intermediate central recessed region defined between the opposite side portions that adapts the body to straddle an intermediate slot between the spaced slots and a key therein and also straddle partitions in the cavity forming the slots. The elements also include tabs blocking some latches used to releasably lock some individual ink tanks to thereby identify the latch to be used to releasably lock the multi-color ink tank.

Abstract: A multi-color ink tank includes certain features that properly interface with features on a printhead and carrier support structure to operatively seat the ink tank in the carrier support structure in a sealed flow communicative relationship with the printhead. These interface features are spaced apart relative to one another at distances (or dimensions) that ensure the desired seating and sealing of the ink tank in the carrier support structure and thereby the reliable supply of ink for operation of the inkjet printing system.

Abstract: A mono ink tank includes certain features that properly interface with features on a printhead to operatively seat the ink tank in the printhead in a sealed flow communicative relationship with the printhead. These interface features are spaced apart relative to one another at distances (or dimensions) that ensure the desired seating and sealing of the ink tank in the printhead and thereby the reliable supply of ink for operation of the inkjet printing system.

Abstract: An ink tank includes a reservoir body for containing an ink supply. The reservoir body has a top opening. A top cover is attached to the reservoir body to close the top opening. The top cover has an outer surface. The top cover is formed from a molded material. An RFID tag is integrated into the top cover by one of insert molding the RFID tag in the top cover when the top cover is molded or securing the RFID tag in a recessed region of the top cover.
