US 12,197,143 B2 · Image forming apparatus and information processing device

Abstract

An image forming apparatus includes an image forming unit configured to form an image with toner, a halftone processor configured to convert image data by performing halftone processing, a first determining unit configured to determine a first toner consumption amount for each page based on the image data, a second determining unit configured to determine a second toner consumption amount for each page based on the converted image data, a print percentage calculator configured to calculate a print percentage for one page based on the first toner consumption amount, a notifying unit configured to notify a remaining amount of the toner of the image forming unit based on the first toner consumption amount of a page of which the print percentage is larger than a threshold and the second toner consumption amount of a page of which the print percentage is equal to or smaller than the threshold.

Dependent claims

An image forming apparatus comprising:

a halftone processor configured to convert image data by performing halftone processing;
an image forming unit configured to form an image with toner based on the image data converted by the halftone processor;
a first determining unit configured to determine a first toner consumption amount for each page based on the image data before conversion by the halftone processor;
a second determining unit configured to determine a second toner consumption amount for each page based on the image data after conversion by the halftone processor;
a print percentage calculator configured to calculate a print percentage for one page based on the first toner consumption amount;
and
a notifying unit configured to notify of a remaining amount of the toner of the image forming unit based on the first toner consumption amount of a page of which the print percentage is greater than a threshold and the second toner consumption amount of a page of which the print percentage is equal to or less than the threshold.

4 more elements

An information processing device which is communicably connected to a printer configured to form an image with toner based on image data, the information processing device comprising:

a halftone processor configured to convert image data by performing halftone processing and transmit the image data to the printer, wherein the printer forms the image based on the converted image data transmitted from the halftone processor;
a first calculator configured to calculate a first toner consumption amount for each page based on the image data before performing the halftone processing by the halftone processor;
a second calculator configured to calculate a second toner consumption amount for each page based on the converted image data;
a print percentage calculator configured to calculate a print percentage for one page based on the first toner consumption amount;
and
an outputting unit configured to output a remaining amount of the toner of the image forming unit based on the first toner consumption amount of a page of which the print percentage is greater than a threshold and the second toner consumption amount of a page of which the print percentage is equal to or less than the threshold.
