Chapter 22-7F-2-72.4.1.2 Print Process 0013-7399/ i-SENSYS LBP5360 / i-SENSYS LBP5300The principle of the image formation is described here.The print process can be broadly divided into 5 blocks with 10 steps. A toner image is formed on paper as it goes through each process.The following is the blocks and the steps of print process and the diagrammatic sketch.1. Electrostatic latent image formation blockTo form an electrostatic latent image on the photosensitive drum.Step 1: Pre-exposureStep 2: Primary chargingStep 3: Laser beam exposure2. Development blockTo make the electrostatic latent image visible on the photosensitive drum surface with the contact development method.Step 4: Development3. Transfer blockTo transfer toner image on the photosensitive drum onto paper.Step 5: AttractionStep 6: TransferStep 7: Drum separationStep 8: ETB separation4. Fixing blockTo fix the toner image on paper.Step 9: Fixing5. Cleaning blockTo clean the residual toner on the photosensitive drum.Step 10: Drum cleaningVideo DataATTTRDEVPRIPREEXPETBBkYCMFixing unitLaser/Scanner unit Laser beamPrimary exposure LEDMemory tag Attraction rollerTo developingbladeTo developingrollerVideocontrollerPCBDC controller PCB High-voltagepower supply PCBVIDEOsignalsTo primarycharging rollerBL
