Embodiment Construction

[0022] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0023] Such as figure 1 A method for accurately measuring toner consumption shown, a method for accurately measuring toner consumption, includes the following steps:

[0024] Step S1, calculate the toner consumption required to print 100% coverage of a piece of paper, and store it as the standard toner consumption p;

[0025] Step S2, obtaining the content to be printed, and calculating the percentage of the area to be covered by toner in the area of ​​the entire paper surface in the content to be printed on each side;

[0026] Step S3, multiplying the percentage calculated in step S2 by the standard toner consumption stored in step S1 to obtain the toner consumption P of the content to be printed on each side;

[0027] Step S4, accumulating the toner consumption of the content to be printed on each side to obtain the total toner consumption ΣP of thi...

Abstract

The invention relates to a method for accurately metering powdered ink consumption, a control system and a laser printer, and belongs to the technical field of laser printers. The method for accurately metering toner consumption, which comprises the following steps of: S1, calculating the toner consumption required for printing 100 percent of a paper surface, and storing the toner consumption as standard toner consumption p; s2, obtaining to-be-printed content, and calculating the area percentage of the area needing to be covered by the powdered ink in each surface of the to-be-printed contentin the whole paper surface; s3, multiplying the percentage calculated in the step S2 by the standard toner consumption stored in the step S1 to obtain the toner consumption P of the to-be-printed content on each side; and S4, accumulating the toner consumption of the to-be-printed content on each side to obtain the total toner consumption sigma P of the printing. The laser printer toner cartridgesolves the problems of inaccurate metering of the toner in the laser printer toner cartridge, large waste and environmental pollution.

Description

technical field [0001] The invention relates to a method for accurately measuring toner consumption, a control system and a laser printer, belonging to the technical field of laser printers. Background technique [0002] A laser printer is a non-impact output device that combines laser scanning technology and electronic imaging technology. Its working principle basically goes through seven processes: charging, exposure, development, transfer, power elimination, cleaning, and fixing. (Also known as toner), is the powdery substance used for imaging and fixing on paper in laser printers. It is mainly stored in the toner cartridge of the toner cartridge. When it is almost used up, the printed content will fade and affect the user experience. , so it is necessary to measure the consumption of the toner, and prompt the user to replenish or replace it before it is exhausted. [0003] At present, laser printers generally measure toner by counting the number of prints, but in fact, ...
