Abstract
The invention provides a method for preventing a development roller from being polluted. The method includes the following steps: step one, blowing carbon powder on the surface of the development roller cleanly; step two, reversing the development roller for 1/3 circle, using the cleanly-blown surface of the development roller for cleaning carbon powder on the edge of a doctor blade during rolling, and enabling no residual carbon powder to exist between contact surfaces of the development roller and the doctor blade; step three, blowing the carbon powder on the surface of the development roller cleanly again; step four, repeating step one to step three for at least twice; step five, providing a special release paper; and inserting the release paper in the space between the doctor blade and the development roller, with the smooth side of the release paper facing the development roller and the rough side facing the doctor blade; step six, reversing the development roller, enabling the release paper to roll into the space between the development roller and the doctor blade for a certain depth, and enabling no residual carbon powder to exist between the development roller and the doctor blade which are then completely separated. According to the method for preventing the development roller from being polluted, the development roller and the doctor blade are separated by the release paper and have no residual carbon powder between; accordingly the development roller can be prevented from being polluted. The method for preventing the development roller from being polluted has the advantages of being simple to operate, practical, and capable of being popularized widely.
Description
Technical field
The present invention relates to the printing consumables field, especially relate to a kind of contaminated method of developer roll that prevents.
Background technology
Enterprise uses to terminal client through the good toner cartridge of production line production at present, and toner cartridge has a lay-up period.This lay-up period comprises: enterprises is deposited → transportation → terminal client toner cartridge the depositing of toner cartridge → transportation → sole distributor.This lay-up period is short then one to two months, and is long then more than half a year.Environmental factor during this time can be brought influence in various degree to toner cartridge.Particularly generally all contact with each other and push phenomenon between attrition component and attrition component in the toner cartridge, the toner cartridge of many different models holds dare not accept various environmental changes and long-time extruding, thereby defective occurs because of the difference on the attrition component, directly influences print quality.
Improving storage condition and traffic condition can not head it off, and the defective that extruding produces can not get solving; Just directly increased cost and change attrition component, can not accomplish the end in view.
Summary of the invention
In view of this, be necessary, provide a kind of and prevent to avoid powder delivery cutter and the mutual extruding of developer roll to make developer roll contaminated, thereby influence the method for print quality to the problem of mentioning in the background technology.
The objective of the invention is to realize through following technical scheme:
A kind of contaminated method of developer roll that prevents, it may further comprise the steps:
The first step, the carbon dust that developer roll is surperficial blow clean;
Second step, discharged-area development roller 1/3 circle, the one side of utilizing developer roll to be blown clean is become a cadre the carbon dust on the powder delivery cutter edge of a knife only, makes noresidue carbon dust between developer roll and the powder delivery cutter surface of contact;
The 3rd goes on foot, developer roll surface carbon dust is blown clean again;
The 4th step, three steps at least twice of the repetitive operation first step to the;
The 5th goes on foot, provides a special-purpose barrier paper, and this barrier paper is inserted between powder delivery cutter blade and the developer roll, and smooth one of barrier paper faces developer roll coarse and faces the powder delivery cutter blade;
The 6th step, discharged-area development roller make barrier paper change between developer roll and the powder delivery cutter blade certain depths over to, developer roll is separated with the powder delivery cutter fully and make noresidue carbon dust between the two.
The 6th step, the described degree of depth that barrier paper is changed between developer roll and the powder delivery cutter blade can be selected the 1-5mm scope, preferred 2mm.
Compared to prior art, the invention has the advantages that: the present invention makes developer roll separate with the powder delivery cutter with barrier paper and makes noresidue carbon dust between the two, thereby realizes preventing the contaminated purpose of developer roll; The present invention is simple to operate, practicality, and generalization is strong.
Description of drawings
Fig. 1 is the cross-sectional view of the embodiment of the invention.
Embodiment
The contaminated method of developer roll that prevents that the embodiment of the invention provides may further comprise the steps:
The first step, the carbon dust that developer roll is surperficial blow clean;
Second step, discharged-area development roller 1/3 circle; The one side of utilizing developer roll to be blown clean is become a cadre the carbon dust on the powder delivery cutter edge of a knife only; Purpose is to make noresidue carbon dust between developer roll and the powder delivery cutter surface of contact; As shown in Figure 1, the powder delivery cutter comprises powder delivery cutter knife rest 11 and is installed in the powder delivery cutter blade 12 on the powder delivery cutter knife rest 11;
The 3rd goes on foot, developer roll surface carbon dust is blown clean again;
Twice of the 4th step, three step of the repetitive operation first step to the;
The 5th step, as shown in Figure 1 provided a special-purpose barrier paper 3, and this barrier paper 3 is inserted between powder delivery cutter blade 12 and the developer roll 1, and smooth one of barrier paper 3 faces developer roll 1 coarse and faces powder delivery cutter blade 12;
The 6th step, as shown in Figure 1, discharged-area development roller 1, the degree of depth that barrier paper 3 is changed between developer roll 1 and the powder delivery cutter blade 12 is 2mm, developer roll 1 and powder delivery cutter is separated fully do not have directly that extruding contacts and make the purpose of noresidue carbon dust between the two thereby reach.
Three steps twice of the repetitive operation first step to the described in the 4th above-mentioned step also can be that the repetitive operation first step to the three goes on foot three times or more times.
The above-mentioned described degree of depth that barrier paper is changed between developer roll and the powder delivery cutter blade of the 6th step can be selected 1-5mm scope, preferred 2mm.
The above embodiment has only expressed several kinds of embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
