2. OPERATION DESCRIPTION
OKIPAGE 12i consists of a main control board, a power supply/sensor board, an operator panel,
an electrophotographic process mechanism, and revision for illumination of LED head.
The main control board receives data via the host I/F, it then decodes, edits and stores the data
in memory. After completing the editing of a single page of data, it references the font memory
and generates bit image data, which is transferred to the LED head in one dot line units.
Through the electrophotographic process mechanism, the data is printed on the paper.
The operator panel is used for operations and status display.
