The waste powder collecting assembly 4 further comprises a conducting wire 43 and a charge regulator 44, the cleaning blade 42 is made of conductive materials such as conductive polyurethane and conductive metal, the cleaning blade 42 is fixedly connected and electrically connected to the conducting wire 43, and the other end of the conducting wire 43 is electrically connected to the charge regulator 44, so as to control the condition of the cleaning blade 42 adhering charges through the charge regulator 44, in this embodiment, the charge regulator 44 can control the cleaning blade 42 to adhere positive charges and negative charges, and can also be grounded to remove any kind of charges carried on the cleaning blade 42, so as to switch the condition of the adhering charges of the cleaning blade 42 according to actual requirements.
When the cleaning blade 42 is grounded, the cleaning blade 42 can eliminate the charges carried by the waste powder when contacting the photosensitive drum 21, so that the waste powder can smoothly fall into the waste powder bin 41 without being influenced by the charges; at present, the laser printer usually adopts a mode of irradiating the photosensitive drum 21 by a discharge lamp to eliminate residual charges on the photosensitive drum 21, and the cleaning blade 42 can also play a role of eliminating the residual charges on the photosensitive drum 21 under the condition of grounding, so that the structure of the laser printer is convenient to simplify; on the other hand, the cleaning blade 42 may also perform the function of attracting the excess toner by carrying an electric charge opposite to that of the excess toner to perform the effect of cleaning the excess toner on the photosensitive drum 21 in another form, and the user may select the cleaning mode according to the actual demand.
The implementation principle of the embodiment is as follows: when printing is performed using a printer cartridge employing a waste toner collection assembly, paper 100 is fed from the paper supply assembly into the paper 100 path, toner is printed onto the surface of paper 100 via photoreceptor drum assembly 2, and then paper 100 is moved to fuser assembly 12, where the toner melts and forms a solid image on paper 100.
After the transfer work of the photosensitive drum 21 is completed, toner still remains on the surface, and the remaining toner is mixed with impurities such as dust, paper dust, and the like, and when the remaining toner rotates along with the photosensitive drum 21 to abut against the cleaning blade 42, the remaining toner is scraped by the cleaning blade 42 and falls into the waste toner bin 41, so that the purpose of discarding the toner containing the impurities is achieved.
