Abstract

The figure shows an ink jet printer in which a multiple printhead cartridge assembly 10 is driven along a guide rail 12 by a belt 14 driven by motor 16. Cartridge assembly 10 consists of a first color cartridge 20 having two or more color ink jet cartridges and a second black cartridge 22 detachably connected to cartridge 20 by an electricallmechanical coupler 24. The cartridge assembly is shown parked in a non-printing position such as a maintenance station. For a black-only print operation onto sheet 26, the black cartridge 22 is detached from color cartridge 20 and is moved through a print cycle. For a color printing, the entire assembly 10 is moved through a print cycle. By providing for a separable black printhead for black-only printing, the mass of the assembly 10 is reduced
