Chapter 2 Operation Description
OKIPAGE 6e, OKIPAGE 6ex consists of a Main Control PCB, a power supply/sensor board, a PostScript
board (OKIPAGE 6ex), an operator panel and an electrophotographic process mechanism.
The soft operator panel is used for operation and status display of OKIPAGE 6e and OKIPAGE 6ex.
The operator panel is used for operation and status display of OKIPAGE 6ex.
The OKIPAGE 6e and OKIPAGE 6ex receive data via the host I/F, these then decode, edit and store the
data in memory. Bit map image data is successively transferred to the LED head in one dot line units.
OKIPAGE 6e block diagram is shown in Figure 2-1.
OKIPAGE 6ex block diagram is shown in Figure 2-2.
