Abstract
Even in the case where preliminary ejection is performed by a recording head having an array of pigment ink ejection outlets and an array of dye ink ejection outlets in which a length of the pigment ink ejection outlet array is longer than a length of the dye ink ejection outlet array, deposition of preliminarily ejected pigment ink at a preliminary ejection receiving portion is effectively prevented by providing an inclined surface at the preliminary ejection receiving portion so that ink from the dye ink ejection outlets is received at an upstream position of the inclined surface and ink from the pigment ink ejection outlets is received at a downstream position of the inclined surface in a direction of gravity.
Claims9
An ink jet recording apparatus for effecting recording on a conveyed recording medium by an ink jet recording head having a pigment ink ejection outlet array for ejecting pigment ink and a dye ink ejection outlet away for ejecting dye ink, the dye ink ejection outlet array having a length shorter than that of the pigment ink ejection outlet array, said ink jet recording apparatus comprising:
- a carriage for mounting and moving the recording head;
- a cap for capping ejection outlets of the recording head;
- and
- a preliminary ejection receiving portion disposed opposite to said cap in a recording area with respect to a movement direction of the recording head,
- wherein said preliminary ejection receiving portion has an inclined surface, along a conveyance direction of the recording medium, located so that the dye ink ejection outlet array is disposed upstream from the pigment ink ejection outlet array with respect to a direction of gravity when the recording head is located opposite to said preliminary ejection receiving portion.
