Step 2 Laser exposure process Forms an electrostatic latent image on the photosensitive drum. Step 3 Developing process Makes an electrostatic latent image visible. Step 4 1st transfer process Forms an image by synthesizing on the transfer belt a mono- chrome (YMCK) visible image from each photosensitive drum. Step 5 2nd transfer process Transfers an image on the transfer belt to paper. Step 6 Separation process Separates paper from the transfer belt after completion of the transfer of the toner. Sub step 1 Drum cleaning Removes toner adhered on the surface of the photosensitive drum after completion of the primary transfer.
Sub step 2 Pre-charging exposure Removes residual potential on the surface against the photosen- sitive drum after completion of drum cleaning. Sub step 3 Transfer belt cleaning Removes toner adhered on the surface of the transfer belt after completion of the 2nd transfer. Sub step 4 2nd transfer roller L cleaning Remove toner adhered on the 2nd transfer roller L after comple- tion of the 2nd transfer. Sub step 5 Toner collection Collects toner that has been removed through the drum cleaning and the transfer belt cleaning. (Not shown in the drawing below.)
