What are the copier accessories?

Copier accessories 1. Charging parts (high voltage generator, electrode frame and motor wire): evenly charge the surface of the photosensitive drum.

Copier accessories 2. Exposure parts (scanning exposure lamp, reflector and lens): make the surface of the photosensitive drum form an inverted potential latent image of the image according to the original image.

Copier accessories 3. Developing parts (developer, high voltage generator): convert the potential latent image on the surface of the photosensitive drum into toner image.

Copier accessories 4. Paper feeding parts (motor and paper take-up wheel): the motor drives the paper take-up wheel to feed the copy paper into the machine to prepare for the next step of transferring the toner image on the drum surface to the paper.

Copier accessories 5. Transfer parts (high voltage generator, electrode holder and motor wire): the surface of the copy paper is evenly charged opposite to the toner charge through the transfer electrode to transfer the toner image on the photosensitive drum to the copy paper.

Copier accessories 6 Separating parts (high voltage generator, electrode holder and motor wire): since the surfaces of the copy paper and the photosensitive drum are charged and have opposite polarity, it is difficult for the copy paper to be separated from the photosensitive drum during the copy process. Therefore, separation measures need to be taken to successfully separate the copy paper completing the copy from the drum. Earlier copiers used mechanical separation, but it is easy to jam; current copiers are Current separation is adopted. The separation current contains high-frequency AC and fixed DC components.

Copier accessories 7. Cleaning parts (cleaner): clean the residual toner on the surface of the photosensitive drum to prepare for the next copy. All copiers cannot transfer the toner on the surface of the photosensitive drum completely to the copy paper through transfer. Therefore, there is residual toner on the surface of the drum. If it is not cleaned, the quality of future copies will be affected.

Copier accessories 8. Fixing parts (fixing hot stick, pressure stick and heater): the toner image on the copy paper is fixed on the copy paper through fixing for easy storage. If it is not fixed, the image on the copy paper will fall off as soon as it is touched. (therefore, fixing requires a certain temperature and pressure)

Copier accessories 9. Power dissipation part (full exposure lamp): remove the residual potential on the surface of the photosensitive drum to prepare for future copying. Otherwise, the copy will have residual image or bottom ash.

Copier accessories 10. Edge erasing parts (inter image edge erasing lamp): the copies have gaps in the front end, front and rear sides, rear end or reduced part, so it is necessary to remove the unnecessary surface potential of the photosensitive drum through the inter image edge erasing lamp.
