a counter processor configured to obtain selected one of: a total counter value of the color counter based on the first counter value and the third counter value; and a total counter value of the monochrome counter based on the second counter value and the third counter value, wherein
the counter processor obtains the total counter value of the color counter by multiplying the third counter value with a weighting factor to generate a weighted third counter value and subtracting the weighted third counter value from the first counter value, the total counter value of the color counter being used for determination of a charge fee of the image forming apparatus based on a unit charge fee previously set for the full-color printing mode, and
the counter processor obtains the total counter value of the monochrome counter by multiplying the third counter value with a weighting factor to generate a weighted third counter value and adding the weighted third counter value to the second counter value, the total counter value of the monochrome counter being used for determination of a charge fee of the image forming apparatus based on a unit charge fee previously set for the monochrome printing mode.
2. The image forming apparatus of claim 1, further comprising:
an interface unit configured to receive a user instruction input by a user, wherein a value of the weighting factor is determined according to the user instruction.
3. The image forming apparatus of claim 1, further comprising:
an interface unit configured to receive a user instruction input by a user, wherein the counter processor determines whether to obtain the total counter value of the color counter or the total counter value of the monochrome counter according to the user instruction.
4. The image forming apparatus of claim 1, further comprising:
a display unit configured to display at least one of the total counter value of the color counter and the total counter value of the monochrome counter.
5. A method of managing a charge fee of an image forming apparatus, the method comprising:
counting a number of sheets to be printed in a full-color printing mode using a color counter to generate a first counter value;
counting a number of sheets to be printed in a monochrome printing mode using a monochrome counter to generate a second counter value;
counting a number of sheets to be printed in an economical printing mode to generate a third counter value, wherein the economical printing mode causes the image forming apparatus to form an image with colorant having a number of colors that is less than a number of colors used for the full-color printing mode or with colorant having an amount less than an amount of colorant used for a printing mode in which the economical printing mode is not set;
obtaining selected one of: a total counter value of the color counter based on the first counter value and the third counter value; and a total counter value of the monochrome counter based on the second counter value and the third counter value, wherein
the total counter value of the color counter is obtained by multiplying the third counter value with a weighting factor to generate a weighted third counter value and subtracting the weighted third counter value from the first counter value, the total counter value of the color counter being used for determination of a charge fee of the image forming apparatus based on a unit charge fee previously set for the full-color printing mode, and
the total counter value of the monochrome counter is obtained by multiplying the third counter value with a weighting factor to generate a weighted third counter value and adding the weighted third counter value to the second counter value, the total counter value of the monochrome counter being used for determination of a charge fee of the image forming apparatus based on a unit charge fee previously set for the monochrome printing mode.
6. The method of claim 5, further comprising:
receiving a user instruction input by a user; and
determining a value of the weighting factor according to the user instruction.
7. The method of claim 5, further comprising:
receiving a user instruction input by a user; and
determining whether to obtain the total counter value of the color counter or the total counter value of the monochrome counter according to the user instruction.
8. The method of claim 5, further comprising:
displaying at least one of the total counter value of the color counter and the total counter value of the monochrome counter.
9. A recording medium storing a plurality of instructions which cause a processor, when executed, to perform a method of managing a charge fee of an image forming apparatus, the method comprising:
counting a number of sheets to be printed in a full-color printing mode using a color counter to generate a first counter value;
counting a number of sheets to be printed in a monochrome printing mode using a monochrome counter to generate a second counter value;
counting a number of sheets to be printed in an economical printing mode to generate a third counter value, wherein the economical printing mode causes the image forming apparatus to form an image with colorant having a number of colors that is less than a number of colors used for the full-color printing mode or with colorant having an amount less than an amount of colorant used for a printing mode in which the economical printing mode is not set;
obtaining selected one of: a total counter value of the color counter based on the first counter value and the third counter value; and a total counter value of the monochrome counter based on the second counter value and the third counter value, wherein
the total counter value of the color counter is obtained by multiplying the third counter value with a weighting factor to generate a weighted third counter value and subtracting the weighted third counter value from the first counter value, the total counter value of the color counter being used for determination of a charge fee of the image forming apparatus based on a unit charge fee previously set for the full-color printing mode, and
the total counter value of the monochrome counter is obtained by multiplying the third counter value with a weighting factor to generate a weighted third counter value and adding the weighted third counter value to the second counter value, the total counter value of the monochrome counter being used for determination of a charge fee of the image forming apparatus based on a unit charge fee previously set for the monochrome printing mode.
