Abstract
A liquid absorbent for ink contains a cellulose fiber, a heat-fusible material, and a flame-retardant material. The absorbent satisfies the relation σ1−σ0≦500, where σ0 [μS/cm] is the electric conductivity of the ink and σ1 [μS/cm] is that of a mixture of 5 g of the ink and 1 g of the flame-retardant material.
Claims9
An ink jet printer comprising:
- a print head that prints on a paper using an ink;
- and
- an ink absorbent that absorbs the ink, the ink having an ink conductivity of σ0 [μS/cm],
- wherein the ink absorbent comprises a cellulose fiber, a heat-fusible material, and a flame-retardant material;
- and
- the flame-retardant material satisfies a relation of σ1−σ0≦500, where σ1 [μS/cm] is an electric conductivity of a mixture of 5 g of the ink and 1 g of the flame-retardant material.

An ink jet printer comprising:
- an ink cartridge;
- and
- an ink absorbent positioned within the cartridge for absorbing a waste ink, the waste ink having an ink conductivity of σ0 [μS/cm],
- wherein the ink absorbent comprises a cellulose fiber, a heat-fusible material, and a flame-retardant material;
- and
- the flame-retardant material satisfies a relation of σ1−σ0≦500, where σ1 [μS/cm] is an electric conductivity of a mixture of 5 g of the waste ink and 1 g of the flame-retardant material.
