A printhead assembly for a pagewidth ink jet printer includes an ink storage assembly that defines at least one ink storage chamber. An elongate mounting member is mounted on the ink storage assembly to be in fluid communication with the, or each, ink storage chamber. At least one printhead module is mounted on the mounting member and has a carrier that defines a recess and a printhead chip received in the recess. The recess is in fluid communication with the mounting member so that ink from the, or each, ink storage chamber can be fed to the printhead chip.

A modular printhead is provided for an inkjet printer. The printhead includes an elongate mounting member defining a channel. A plurality of elongate printhead modules is arranged end to end within the channel. Each printhead module has complementary nesting formations at either end so that adjacent printhead modules are nested together. Each printhead module includes an elongate printhead integrated circuit (IC) which is configured to print ink, and is aligned obliquely with respect to the mounting member so that adjacent printhead ICs overlap along the mounting member and provide for continuity of printing on print media which passes across the printhead.
摘要:
A low cost medical humidifier for adding moisture to a patient air flow is disclosed. The humidifier comprises a water reservoir, a disposable evaporative wick containing a heater, a lid containing electrical contacts to engage the heater in the wick and airway connections. The wick heater comprises a PET film with aluminum tracks and a cover layer of PTC resistive ink. The heater is covered with paper to provide a water pathway via capillary flow. There is a capillary path from the water reservoir to the wick. The wick and heater are manufactured with printing and calendaring processes in reel to reel processes.
