Chapter 2 Operation Description
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.
