Abstract
The invention provides a disposable ink cartridge to be installed in an existing all-in-one printhead-ink cartridge to form an assembled segregated printhead-ink cartridge for use in a printer. The all-in-one printhead-ink cartridge has a printhead with a printhead chamber from which any cover and ink-absorbent materials have been removed. The disposable ink cartridge includes an ink cartridge body, an assembly-securement member and a cartridge seal holder. The ink cartridge body further includes a cartridge housing, a cartridge cover, at least one air vent cover, at least one ink-storing foam, at least one ink-filtering foam, at least one sealing member, which are integrated into one indivisible entity fitting into the chamber of the printhead. When the disposable cartridge runs out of ink, what is needed is just to replace the ink cartridge body without replacing the printhead and the assembly-securement member, thus making the originally disposable printhead repeatedly usable.
