Description

Handle box page output and page or leaf powder consumption pick-up unit and detection method

Technical field

A kind of pick-up unit and the detection method thereof used when the present invention relates to the electronic photographicing image forming device and making with handle box.

Background technology

The electronic photographicing image forming device comprises laser printer, duplicating machine etc., handle box is and the collaborative work of electronic photographicing image forming device, to print the vitals to the medium as the carbon dust of toner, simultaneously, handle box also is a carbon dust container, consumable container has great market demand in other words conj.or perhaps.

It now is example with the laser printer, principle of work to electronic photographicing image forming device and the closely related part of the present invention is summarized as follows, each sheet medium---printer paper is finished to printing from entering printer, generally need through three sensors, one is to add paper sensor, another is the development paper sensor, and another is the photographic fixing paper sensor.After one stacker is opened and is put into the printer paper storing box, height or weight by paper are opened the photoelectricity shadow shield, the photosensitive tube conducting provides a low level signal for the CPU of printer, and CPU detects paper in the paper storing box, after last paper uses up in the paper storing box, the shadow shield of photoelectric sensor resets, and blocks light path again, and photosensitive tube ends, and providing high level signal to printer cpu, CPU detects does not have paper.

The development paper sensor is identical with the principle of work that adds paper sensor with the principle of work of photographic fixing paper sensor, just when printing for many, they to what printer cpu provided are, is the pulse signal in cycle with every paper and every two pieces of paper gap by sensor, and they have identical cycle, frequency and amplitude.

The work of handle box divides roughly as followsly to the process in downstream from the upstream by photosensitive drums, charging roller charged to photosensitive drums before this; Laser beam in the printer scans photosensitive drum surface and forms the image latent image area; The magnetic roller feeds to latent image area with the carbon dust in the toner; The carbon dust of latent image area is passed to transfer roll; Cleaning device is with carbon dust clearing residual on the photosensitive drums and send in the waste powder hopper of handle box, so far finishes a work period, carries out the charging of next cycle again.

In the manufacture process of handle box, in accordance with regulations, every manufacturing is a collection of all will be inspected by random samples this batch, comprising according to the STM-1856 standard-required, " E " letter of test coverage 5% promptly, is printed " E " letter standard testing page or leaf with a handle box on printer, consumed until carbon dust, this batch processing box of sampling statistics whenever can only print how many standard pages and every page consumption powder what.

At present, for finishing this detection requirement, handle box for different model, the detection of each sample box need expend 1 to 4 working day, expend thousands of to Zhang Jiezhi up to ten thousand, in addition, to the consumable accessory in the electronic photographicing image forming device, consume also quite big as fuser, paper-sheets rolling wheel, paper-feed roll etc.

Summary of the invention

Fundamental purpose of the present invention is to provide a kind of pick-up unit of handling box page output and page or leaf powder consumption that is used to detect;

Another object of the present invention is to provide a kind of page or leaf output and page or leaf powder consumption pick-up unit that need not medium, the recyclable utilization of carbon dust;

A further object of the present invention is to provide a kind of detection method of handling box page output and page or leaf powder consumption that detects.

For achieving the above object, technical conceive of the present invention is one and adopts the printer emulation paper feed, do not have the scheme that carbon dust was printed and collected to paper.Promptly adopt a pulse signal generator, it is exported a low level all the time and gives electronic photographicing image forming device CPU as adding the paper signal, and respectively to electronic photographicing image forming device CPU output development paper pulse signal and photographic fixing paper pulse signal, CPU is just obtaining under the situation of above-mentioned signal together not having normal printing under the paper state with handle box.Write down the total number of pulse in above-mentioned arbitrary pulse signal by a pulse count signal device again, thereby realize statistics total printing " paper " quantity.In the electronic photographicing image forming device, install a carbon dust gathering-device additional, it is arranged on the upstream of handle box cleaning device, be used for collecting before carbon dust enters the handle box waste powder hopper, owing to be that no paper is printed, be not subjected to the pollution of paper surface fiber, dust in the carbon dust of collecting, can use repeatedly.

Detection method provided by the invention comprises:

The pulse signal control circuit that will have impulse meter is connected to the input end of electronic photographicing image forming device CPU, and signal comprises that is exported low level paper signal, a development paper pulse signal and the photographic fixing paper pulse signal of adding all the time in the arteries and veins;

Install a carbon dust gathering-device additional at described electronic photographicing image forming device transfer roll or handle box photosensitive drums place;

With the handle box to be measured described electronic photographicing image forming device of packing into;

Start described electronic photographicing image forming device and described pulse signal control circuit, the consumption in the handle box to be measured is intact;

From the data that impulse meter provides, obtain count value, obtain a page output, and then converse a page powder consumption;

From the carbon dust gathering-device, reclaim carbon dust.

By above scheme as seen, the technical scheme that the present invention provides need not just can carry out with paper the detection of page output and page or leaf powder consumption, can also be to the carbon dust recycling, under the prerequisite of same realization testing goal, save a large amount of paper and carbon dust, greatly reduce the detection cost.
