Of course, when the chip is mounted on the developing frame 200, the user may also select to use the chip 2 on the photosensitive drum frame 100, increasing the user's selectivity.
When no chip is arranged on the chip mounting position of the developing frame 200, the chip fixing seat 3 is only required to be mounted on the frame body 1, then the developing frame 200 is mounted on the developing frame mounting position 12 on the frame body 1, the developing frame 200 and the photosensitive drum frame 100 are assembled to form a processing box and then are mounted on the printer body together, at the moment, the electric connection part on the printer body is contacted with the chip 2 on the photosensitive drum frame 100, and the printer body recognizes the processing box through the detection wheel on the developing frame 200 and the chip 2 on the photosensitive drum frame 100.
Therefore, no matter whether a chip is arranged on the developing frame 200 or not, the developing frame can be matched with the photosensitive drum frame 100, the universality of the photosensitive drum frame 100 is strong, the use and the operation are simple and convenient, and the economy is good; and when there is a chip on the developing frame 200, the user can also select a chip to be used (select to use the chip on the developing frame 200 or select to use the chip 2 on the photosensitive drum frame 100), and the user's choice is more.
