2. OPERATION DESCRIPTION
The OKIPAGE 4w consists of a main control board, a high-voltage power supply board, a power
supply unit, and an electro-photographic processor. The OKIPAGE 4w receives print data from
a higher-level interface and sequentially stores it in memory. The OKIPAGE 4w 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.
