Exposing
One polygon motor ( 6 facet )
Single beam LD (1ea)
LD wavelength : 785nm
Polygon motor rpm : 23747.5
LSU energy : 0.25uJ/cm^2
OPC exposed potential : -50V
1. Exposing is implemented by laser striking on to OPC with uniform potential
2. Laser beam is modulated according to image to be printed that is from PC
3. Latent Image is formed on OPC, which is developed with toner
Developing
Non-magnetic, mono component
Non-contact development
Developing bias : DC + AC
AC peak to peak : 1.5 ~ 2.0kV
Mass on developing roller : 550 ~ 600ug/cm^2
Toner coulomb : 15 ~ 20uC/g
Roller diameter : 10mm
Roller resistivity : 10^5 ~ 10^6 ohm-cm
Process speed ratio : 1.2 (OPC=1.0)
Color order : Y -> M -> C -> K
1. Only latent image formed by exposing process is developed with toner
2. AC + DC Voltage is being used to develop toner into latent image on OPC because non-contact
developing method is adopted
3. Y, M, C, and K Images are sequentially developed onto OPC and transferred onto Intermediate
Transfer Belt (hereafter ITB) to form a color image on ITB
4. Toner Bottles are used to supply toner into developer compartment
5. Toner level is being sensed to control toner supply from toner bottle to developer
Transfer 1
Multi-pass transfer
Indirect transfer
Transfer voltage : 0.5 ~ 2.0kV (controllable)
Roller diameter : 14mm
Roller resistivity : ~ 10^7 ohm-cm
Belt resistivity : 10^9 ~ 10^11 ohm-cm
Environment sensing by Y-transfer roller
Transfer unit life : 50K images
1. Developed Image on OPC is transferred onto ITB by T1 Process
2. T1 Voltage is positive which attract toner to ITB
3. 4 times of T1 process is required to make a color image on ITB, which means multi-pass process
4. ITB has a hole as a fiducial mark for timing. Engine control for color image is synchronous with it,
ITB Home Sensing Signal
