Embodiment Construction
[0024] Embodiments are described below with reference to the drawings.
[0025] Such as figure 1 As shown, the process box 1 includes a waste toner bin 2 and a powder bin 3; the waste toner bin 2 is provided with a photosensitive drum 7, a charging roller 11 and a cleaning blade 15; the toner bin 3 is provided with a developing roller 9 and a powder outlet knife 13 ; A laser port 16 is formed between the waste toner bin 2 and the powder bin 3 . The photosensitive drum 7 has a photosensitive drum steel shaft 7a, the developing roller 9 has a developing roller steel shaft 9a, and the charging roller 11 has a charging roller steel shaft 11a.
[0026] During the working process of the electrophotographic imaging device, the process cartridge is installed on the electrophotographic imaging device, and the photosensitive drum steel shaft 7a is connected with the electrodes on the electrophotographic imaging device, and finally grounded. The steel shaft 9a of the developing roller ...

The invention relates to detection equipment for anti-pollution paper of a process cartridge. The process cartridge comprises a photosensitive drum, a primary charge roller and a developer roller. Thedetection equipment for the anti-pollution paper is characterized by comprising a switch, an indicator light, a first support plate, a second support plate as well as a primary charge roller conductive contact, a photosensitive drum conductive contact and a developer roller conductive contact which are arranged on the first support plate, wherein the second support plate is arranged on the side,corresponding to the first support plate, of the detection equipment; a motor I, a photosensitive drum drive shaft and a connecting rod connected with the motor I are further arranged on the detectionequipment, and the other end of the connecting rod is connected with a piston; a detection component I and a detection component II are further arranged on the detection equipment for the anti-pollution paper; the detection component I is connected with the primary charge roller conductive contact and the photosensitive drum conductive contact; the detection component II is connected with the developer roller conductive contact and the photosensitive drum conductive contact. With adoption of the equipment, the anti-pollution paper is detected more conveniently and more rapidly while the process cartridge cannot be damaged.
Description
technical field [0001] The invention relates to an electrophotographic imaging device, such as a process box used on a laser printer, a copier or a facsimile machine; more specifically, the invention relates to a detection method and a detection device for whether the anti-pollution paper on the process box is installed in place. Background technique [0002] The processing cartridge of the prior art includes a photosensitive drum, a charging roller, and a developing roller; however, during the transportation and storage of the processing cartridge, the charging roller and the developing roller are in contact with the photosensitive drum for a long time, causing the charging roller and the developing roller to contaminate the photosensitive drum. drum. Therefore, the process method of the existing process box is to place the anti-pollution paper between the photosensitive drum and the charging roller or between the photosensitive drum and the developing roller through the to...
