Background technology
Toner cartridge is the common construction store of laser printer, but toner cartridge is during use, carbon dust as in toner cartridge most
Important developer, but generally filling carbon dust 100% can not be consumed all, from the point of view of different toner cartridge structures, be had more than
10% carbon dust is left in toner cartridge bin.During toner cartridge regenerates, due to the manufacture craft of brand-new carbon dust and old carbon dust
With the difference of materials, under relatively uniform matching condition, different printing effects can be presented;Enterprise of the same trade was regenerating
It is general using directly all with changing the way of brand-new carbon dust in journey, the direct waste treatment of old carbon dust progress, this measure causes substantial amounts of
The waste of recycling resource, the pollution of the environment also resulted in.For this at present urgent need develop one kind can by brand-new carbon dust and
The technique that carbon dust is used in mixed way is reclaimed, under the conditions of with other each part match, even better than brand-new carbon dust can be reached
Print quality.
And current carbon dust preparation technology can't accomplish to prepare the higher carbon dust of purity, it is therefore desirable to processing technology
It is improved.
The content of the invention
For defect of the prior art, it is an object of the invention to provide a kind of regeneration work of printer waste carbon powder
Skill.
A kind of regeneration technology of the printer waste carbon powder provided according to the present invention, the printer waste carbon powder
