Description
Technical Field
The invention relates to the technical field of electrophotographic imaging, in particular to a large-capacity powder box.
Background
The existing powder box wastes a lot of space due to the fact that a larger gap is formed between the developing box and the drum box and the size of the handle is large, and meanwhile due to the limitation of the whole structure of the powder box and the space of a printer, the space of a powder cabin of the powder box is smaller, the capacity of accommodated carbon powder is low, and the yield of printing pages is lower. When the end user uses up the carbon powder in the powder box, the photosensitive drum of the powder box can also continue to use, other parts in the powder box can also continue to use, if the powder box is discarded, unnecessary waste of parts such as the photosensitive drum and the like can be caused, and the user also needs to buy a new powder box again, so that the use cost of the end user is higher.
The existing powder box expands the capacity of a powder bin by additionally arranging a carbon powder replenishing bin, so that the printing page yield of a product is enlarged. However, in the process of increasing the capacity of the powder bin, because the area of the original waste powder bin is not increased, the increased waste carbon powder printed after the powder bin is increased can continuously enter the waste powder bin, and the small-capacity waste powder bin can accommodate the waste carbon powder amount generated under the same printing page number in the powder bin with large capacity, so that the waste powder in the waste powder bin can not be continuously printed after reaching a certain amount, and the waste powder in the waste powder bin can also cause the internal waste powder to agglomerate when being too much.
In addition, the present powder box that does not have waste powder is through with waste powder storehouse and powder storehouse intercommunication to make the waste powder in the waste powder storehouse obtain cyclic utilization, with reduce cost, however, at the printing in-process, impurity such as wastepaper on the paper can glue on the sensitization drum, when remaining carbon powder is cleared up waste powder storehouse by clean scraper, impurity also can be brought into waste powder storehouse, waste powder has the end ash on the printing paper face when repeated printing, prints the decline of quality. In addition, the electrical property of the carbon powder may change during the working process, and after the waste powder with the changed electrical property enters the powder bin, the carbon powder in the powder bin is agglomerated due to the attraction between the positive and negative charges, so that the printing is influenced.
