OPERATION DESCRIPTION
The OKIPAGE 4w Plus/4m consists of a main control board, a high-voltage power supply board,
a power supply unit, and an electro-photographic processor. The OKIPAGE 4w Plus/4m receives
print data from a higher-level interface and sequentially stores it in memory. The OKIPAGE 4w
Plus/4m decodes and edits the received data while storing print data from the interface in
memory. It sequentially transfers the edited data to the LED head for each dot line. The electro-
photographic processor then prints the data on sheets of paper.
The display of the higher-level host is used for device operation and status display.
Figure 2-1 is the block diagram of the OKIPAGE 4w Plus/4m.
