摘要： Provided is a method of manufacturing a substrate for a liquid discharge head including a first face, energy generating elements which generate the energy to be used to discharge a liquid to a second face opposite to the first face, and liquid supply ports for supplying the liquid to the energy generating elements. The method includes preparing a silicon substrate having, at the first face, an etching mask layer having an opening corresponding to a portion where the liquid supply ports are to be formed, and having first recesses provided within the opening, and second recesses provided in the region of the second face where the liquid supply ports are to be formed, the first recesses and the second recesses being separated from each other by a portion of the substrate; and etching the silicon substrate by crystal anisotropic etching from the opening of the first face to form the liquid supply ports.

摘要： A nozzle ejects a functional liquid having a viscosity of not less than 5 millipascal°second and not more than 20 millipascal°second, onto a substrate. The functional liquid inside a pressure chamber connected to the nozzle is pressurized. A drive voltage having a pull waveform element which causes the pressure chamber to expand from a steady state and a push waveform element which causes the expanded pressure chamber to contract, is generated with a relationship between a slope ?1 representing voltage change per unit time in the pull waveform element, the viscosity ? of the functional liquid, a resonance period Tc of the head, and a slope ?2 representing voltage change per unit time in the push waveform element satisfying (2/Tc) = ?1 = (?/10) and ?2 = ?1.

摘要： An inkjet printer has a printhead cartridge with a pagewidth printhead defining an array of nozzles for ejecting ink onto a media substrate. The printhead cartridge has a fluid coupling in fluid communication with the array of nozzles. The printer also has a cradle for supporting the printhead cartridge such that the array of nozzles is adjacent a media feed path extending through the printer, the cradle having a latch mechanism for retaining the printhead cartridge, an ink reservoir for containing supply of ink and a complementary coupling for fluid communication with the ink reservoir. The fluid coupling and the complementary coupling are configured to establish a sealed fluid connection using mechanical advantage provided by user actuation of the latch mechanism to retain the printhead cartridge in the cradle.
