The machine uses an indirect electrostatic method, and is constructed as shown below
F-6-2
The machine's image formation processes can be divided into the following 5 blocks (7steps):
F-6-3
[1] Latent Image Formation Block
Step 1 primary charging (AC + negative DC)
Step 2 laser beam exposure
[2] Developing Block
Step 3 development (AC + negative DC bias)
[3] Transfer Block
Step 4 transfer (positive DC)
Step 5 separation (grounding)
[4] Fixing Block
Step 6 fixing
[5] Drum Cleaning Block
Step 7 drum cleaning
