Page 266: Print Process
Chapter 10 Machine Overview 10.1 Print Process 10.1 Print Process 10.1.1 Outline of Print Process In this device, the print process consists of the seven basic steps to form a toner image on the drum surface, transfer the toner image to paper, and fix (fuse) the transferred image to paper. While the drum surface repeats steps 1 to 5 and 7, paper passes through steps 4 to 6.
Page 267: Explanation Of Print Process
Chapter 10 Machine Overview 10.1 Print Process 10.1.2 Explanation of Print Process [Charge] This steps discharges BCR (Bias Charge Roll) in the Drum/toner cartridge to charge the drum surface (external surface of the optical electric-conductor) with even minus power. - BCR, that is a conductive roller, comes into contact with the drum, and receives the discharge voltage from the HVPS.
Page 268 Chapter 10 Machine Overview 10.1 Print Process [Exposure] This step scans the drum surface charged with minus power by laser beams, and forms a latent electrostatic image on the drum surface. - Laser beams are radiated according to print data sent from the printer controller. When print data instructs the system to print black pixel dots, laser beams are output;...
Page 269 Chapter 10 Machine Overview 10.1 Print Process [Developing] This step draws toner on an invisible latent electrostatic image on the drum surface and forms a visible toner image on the drum. - This device uses dry-type one-component magnetic toner. Toner is supplied from the toner room to the magnet roll adjacent to the drum surface in the Drum/toner cartridge by the agitator.
Page 270 Chapter 10 Machine Overview 10.1 Print Process [Transfer] This step transfers a toner image generated on the drum surface onto paper using the BTR (Bias Transfer Roll) in the BTR ASSY. - The BTR, that is a conductive roller, comes into contact with the drum, and receives the high voltage from the HVPS.
Page 271 Chapter 10 Machine Overview 10.1 Print Process [Fusing] This step dissolves toner on paper and fixes a toner image on paper by pressure. - The toner image transferred from the drum is so fine than it is destroyed only by slightly touching it by fingers.
Page 272 Chapter 10 Machine Overview 10.1 Print Process [Cleaning] The cleaning is divided into three types: physical drum cleaning, electric drum cleaning, and electric BTR cleaning. - Physical drum cleaning This system removes the remaining toner on the drum surface. The remaining toner on the drum surface without being transferred in the [transfer] step is scratch-removed by the cleaning blade coming into contact with the drum surface.

Chapter 10 Machine Overview 10.2 Print Data Flow 10.2 Print Data Flow Print data, that is sent from the printer controller, changes to print image through the following flow: Latent electrostatic image on drum Host (electric signal) Printer controller (electric signal) Toner image on drum (visible image) PWBA MCU (electric signal) Toner image on paper...
