1.1 Print System and Transfer System
Fig.4-7 shows the basic structure of the print system having the OPC belt as the main
part and the transfer system having the transfer drum as the main part. Color printing is
achieved by actuating in sequence each process in the print system and transfer system.
4 cycles of actions 1 to 6 are required to form a full 24 bit color image on the transfer
drum, only one cycle of actions 7, 8 and 9 is required to transfer the image to the paper
from the transfer drum ready for fixing by actions 10 and 11.
