Ink (pigment component ink) is jetted toward an ink absorber (34K) from the nozzle (22K) only of a print head (20K), with no ink jetted from print heads (20C, 20M, 20Y). Next, a carriage (24) is moved in an arrow B′ direction to position the print head (20C) directly above a cap (32K), at that time ink (dye component ink) is jetted toward the ink absorber (34K) from the nozzle (22C) only of the print head (20C) to allow the dye component ink to flow into a waste ink tube (36K). Then, ink (dye component ink) is similarly jetted toward the ink absorber (34K) from the nozzle (22M) only of the print head (20M), whereby the pigment component ink is allowed to flow smoothly without clogging a waste ink tube with a stuck, solid pigment component ink.
An ink-jet image-forming apparatus which has a carriage carrying a pigment-printing head for ejecting a pigment ink and a dye-printing head for ejecting a dye ink and reciprocating in a main scanning direction, and which forms an image by ejecting the ink from the pigment-printing head and the dye-printing head onto a recording medium, wherein the ink-jet image-forming apparatus comprises
An ink-jet image-forming apparatus which has a carriage carrying a pigment-printing head for ejecting a pigment ink and a dye-printing head for ejecting a dye ink, and reciprocating in a main scanning direction, and which forms an image by ejecting the ink from the pigment-printing head and the dye-printing head onto a recording medium, wherein the ink-jet image-forming apparatus comprises
A method for cleaning a waste ink tube for flowing a waste ink sucked or ejected from a pigment-printing head, in an ink-jet image-forming apparatus which has a carriage carrying a pigment-printing head for ejecting a pigment ink and a dye printing head for ejecting a dye ink and reciprocating in a main scanning direction, and which forms an image by ejecting the ink from the pigment-printing head and the dye-printing head onto a recording medium, wherein
