Abstract
A printing apparatus that measures a consumption of a colorant during printing, includes a shade level measuring unit that measures a print shade level on a print sheet, a range segment counting unit that counts the number of print sheets falling within each of a plurality of print shade range segments based on the measurement results of the shade level measuring unit, and an output unit that outputs the count results of the range segment counting unit on a per print shade range segment basis.
Claims6
A printing apparatus that measures a consumption of a colorant during printing, comprising:
- a shade level measuring unit that measures a print shade level on a print sheet;
- a range segment counting unit that counts the number of print sheets falling within each of a plurality of print shade range segments based on the measurement results of the shade level measuring unit;
- and
- an output unit that outputs the count results of the range segment counting unit on a per print shade range segment basis,
- wherein the print shade range segments include an intermediate shade range segment in which the consumption of the colorant increases with the print shade level raised, a low shade range segment in which a constant amount of colorant is consumed even with the print shade level lowered, and a high shade range segment in which the consumption of colorant is not increased above a predetermined amount even with the print shade level raised.
A control method of a printing apparatus that measures a consumption of a colorant during printing, comprising:
- measuring a print shade level on a print sheet;
- counting the number of print sheets falling within each of a plurality of print shade range segments based on the measurement results of the print shade level;
- and
- outputting the count results of print sheets on a per print shade range segment basis,
- wherein the print shade range segments include an intermediate shade range segment in which the consumption of the colorant increases with the print shade level raised, a low shade range segment in which a constant amount of colorant is consumed even with the print shade level lowered, and a high shade range segment in which the consumption of colorant is not increased above a predetermined amount even with the print shade level raised.
A control program for causing a computer to perform a control method of a printing apparatus that measures a consumption of a colorant during printing, comprising:
- measuring a print shade level on a print sheet;
- counting the number of print sheets falling within each of a plurality of print shade range segments based on the measurement results of the print shade level;
- and
- outputting the count results of print sheets on a per print shade range segment basis,
- wherein the print shade range segments include an intermediate shade range segment in which the consumption of the colorant increases with the print shade level raised, a low shade range segment in which a constant amount of colorant is consumed even with the print shade level lowered, and a high shade range segment in which the consumption of colorant is not increased above a predetermined amount even with the print shade level raised.
