Slits are cut in a nozzle tape and aligned with encapsulant beads on a printhead. The slits mechanically decouple portions of the tape stuck to the beads from a central portion of the tape stuck to a nozzle plate, and thereby prevent lifting of the tape off the nozzle plate in the event that the tape subsequently contracts. A method of attaching the tape to the printhead aligns blades with the beads on the printhead, so that the blades cut slits in the tape that are aligned with the beads. The tape is then adhesively secured to the printhead, preserving the alignment.
A nozzle tape for an inkjet cartridge is attached to the inkjet cartridge including a head chip, a cartridge body provided with a head chip-mounting portion spaced apart from edges of the head chip by a predetermined extent, and at least one bead member protruded along the edges of the head chip, wherein the nozzle tape is provided with at least one communication portion in fluid communication with a spaced gap between the head chip and the head chip-mounting portion to make the air trapped under the nozzle tape communicate with external air through the communication portion, thereby tightly attaching the nozzle tape to the nozzles, regardless of changes of an external environment.
A nozzle tape covers substantially all of an outlet portion and an electrical contact portion of a print cartridge. At least one hole provided in the portion of the nozzle tape covering substantially all of the electrical contact portion exposes at least one electrical contact formed on the electrical contact portion. When the cartridge is installed in a print device, such as a printer, a partial electrical connection will be established between the exposed electrical contact and a corresponding electrical contact in the print device. The partial electrical connection may be used to convey a signal to an output device, such as a computer. The signal may indicate that the nozzle tape must be removed before the print cartridge will work properly.

A fluid ejection cartridge includes an ejector head having at least one nozzle and a fluid reservoir containing an ejectable fluid, fluidically coupled with the at least one nozzle. The fluid ejection cartridge has a tape that includes a thermoplastic polymer film in contact with and releasably bonded to the nozzles.
A liquid is applied by a bounded-region applicator such as a needle applicator over nozzle holes and over at least a continuous region close to the nozzle holes. The liquid is then cured to a solid before significant flow of the liquid into the nozzle holes. The liquid is chosen to cure to a solid which is sufficiently compliant that it deforms and leaves the nozzle holes under moderate pressure from a human hand or finger without breaking. Depending upon the material in which the nozzles are formed and the size of the nozzle holes, the liquid may be uniquely designed to incorporate resilient moieties or segments to satisfy these factors.
