Abstract

Disposable printhead cartridges for carriage-type ink jet printers generally comprise a hermetically sealed cartridge containing a quantity of ink under a predetermined pressure and a thermally activated, drop-on-demand printhead integrally bonded thereto. The printhead has a plurality of nozzles connected to a cornmon manifold via capillary fillable ink channels. The manifold is sealingly interconnected to the ink in the cartridge. Such printhead cartridges are removably mounted on a carriage in the printer which is translatable. The carriage traverses back and forth along guide rails during the printing operation. A recording medium is held stationary during the printing of a swath of information by the translating printhead cartridge and is then stepped the distance of the printed swath height at the end of each carriage traversal.
