20090179964 | PRINTHEAD CARTRIDGE INSERTION PROTOCOL - A method of inserting a printhead cartridge in a printer, the printhead cartridge having a printhead with a nozzle face defining an array of nozzles for ejecting ink on to a media substrate fed past the printhead in a media feed direction, by providing a printer with at least three ink tanks for storing the inks of different colour, the printer also having a cradle defining a reference surface for engaging a datum point on the printhead cartridge to support the nozzle face at a precise spacing from a media feed path, a fluid interface in fluid communication with the ink tanks, and a latch for securing the printhead cartridge in the cradle, the latch being movable between an open position where access to the cradle is unobstructed, and a closed position where access to the cradle is obstructed, placing the printhead cartridge in the cradle such that the data point rests on the reference surface while the latch is in the open position, the printhead cartridge having a fluid coupling positioned to align with the fluid interface when placed in the cradle, moving the latch to the closed position to secure the printhead cartridge in cradle, providing a mechanical linkage between the latch and the fluid interface such that the fluid interface sealingly engages the fluid coupling upon moving the latch to the closed position wherein, any force exerted on the printhead cartridge during sealing engagement of the fluid interface and the fluid coupling is not directed to disengage the reference surface from the datum point. | 2009-07-16 |
20090179965 | LIQUID EJECTION HEAD - A liquid ejection head is constituted by a liquid ejection substrate comprising a liquid supply port for supplying liquid, an ejection outlet for ejecting the liquid supplied from the liquid supply port, and ejection energy generating devices for generating energy for ejecting the liquid; and a supporting member having a supporting surface for supporting the liquid ejection substrate and a liquid supply hole for supplying liquid to the liquid ejection substrate, the liquid supply hole communicating with the liquid supply port of the liquid ejection substrate to form a communicating portion, a periphery of which is sealed by a sealant. The liquid supply hole of the supporting member has an opening larger than that of the liquid supply port of the liquid ejection substrate. The support member has an inner wall portion including an edge line portion defined by the liquid supply hole on a side where the liquid ejection substrate is to be disposed. The inner wall portion is covered with the sealant. | 2009-07-16 |
