Detailed Description
IMAGE PROCESS
Charging
Voltage of -1540V is applied to charging roller from HVPS and the drum surface is charged with approximately -900V.
Exposure
19
Laser scanning is performed to the image printing area and the surface electric potential of scanned area drops to about -300V to form ‘Latent Image’.
Development
Images are formed on the drum surface by attaching the charging toner with approximately
-550V via development roller and Doctor blade on the latent image area formed by laser
from exposure stage.
Transfer
20
Images are formed by toner transfer on the drum surface from the Development stage and when paper passes, +2000V of electricity applied to the transfer roller pulls the image forming toner particles on drum surface to form unsettled images on the paper.
Cleaning
Remaining toner on the drum surface after transferred to paper gets trimmed by cleaning blade before getting into charging roller and gets collected in the used toner collecting space.
