Abstract: An improved print-cartridge carriage for ink-jet printers. It contains: (a) a carriage frame having a first recess, a second recess, a pair of spaced L-shaped, and a bearing allowing the carriage frame to be horizontally movable; (b) a gripping spring disposed in the first recess; (c) a pair of spring loaded buttons disposed in the second recess, each of spring loaded buttons has a first bevel surface; and (d) a gripping member having two symmetrically lateral second bevel surfaces. Each of the second bevel surfaces is slidably and respectively engageable with one of the first bevel surface such that the gripping member can be moved relating to the spring loaded buttons and be lifted upwardly when the spring loaded buttons are pressed inwardly.
