becomes the electrostatic latent image.
2. Developing Block
- Step 4: Development [4]
By putting toner to the electrostatic latent image on the surface of the photosensitive drum, turning the image visible. Black toner/color toner of this machine
executes the toner projection development with non-magnetic 2 components development.
3. Transfer Block
The purpose of this block is to transfer the toner image on the surface of the photosensitive drum to a sheet via ITB.
- Step5: Pre-transfer Charging [5]
Although the toner layer of 4 colors are formed on the ITB when executing full color print, potential of each toner varies. Thus, by applying the specified
bias when developing each color, uniform the potential on the toner layer formed on the ITB and increase the efficiency of the primary transfer.
- Step 6: Primary Transfer [6]
By applying the positive charge from the back of the ITB, transfer the toner on the surface of the photosensitive drum to the ITB.
Execute the procedure ti each color (Y,M,C,BK)
- Step 7: Secondary Transfer [7]
Transfer the toner on the ITB belt to a sheet.
- Step 8: Separation [8]
Separate the sheet from the ITB belt.
4. Fixing Block
- Step 9: ITB Cleaning [9]
Fixing the non-fixed toner on a sheet to the sheet with heat and pressure.
5. ITB Cleaning Block
- Step 10: ITB Cleaning [10]
After the secondary transfer, execute the ITB cleaning by contacting the brush roller to the ITB to remove the residual toner on it.
The brush roller attracts the residual toner. The residual toner collected with the brush roller is passed to the bias roller and scraped with the cleaning blade.
The scraped residual toner is collected to the waste toner case placed at the back of the machine with the waste toner delivery screw.

6. Cleaning Block in Secondary Transfer Block
- Step 11: Secondary Transfer Outside Roller Cleaning [11]
Remove the patch image on the ITB or the residual toner on the secondary transfer outside roller, and execute cleaning.
The roller brush that contacts to the secondary transfer outside roller attracts the residual toner.
The residual toner collected with the brush roller is passed to the bias roller, and then, is scraped with the cleaning blade and collected to the waste toner case.
