2. OPERATION DESCRIPTION
OVERVIEW
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.

2.1 Control Board
The control board consists of a single chip CPU, Program & Font ROM's, one or two DRAMs, an
EEPROM, a host interface circuit, and a mechanism driving circuit.
Single Chip CPU
The single chip CPU is a custom CPU (32-bit internal bus, 16-bit or 32-bit external bus, 25.54 MHz
clock with input frequency from a 12.27 MHz clock) which incorporates the RISC CPU and its
peripheral devices, and has the following functions:
Built-in device Function
Chip select controller Control of ROM, DRAM and I/O device
Bus controller
DRAM controller
DMA controller Transfer of image data from DRAM to video output port
Parallel interface controller Control of Centronics parallel interface
Video output port Control of LED head
LED STB output port
Timer Generation of various control timing
Monitoring of paper running and paper size
Serial I/O port Control of operator panel, EEPROM, and options
I/O port Input and output of sensor and motor signals
Program and Font ROM
The Program & Font ROM store the PCL5e emulation program and various types of fonts.
Mask ROM is used for a Program & Font ROM. The mounting location of this Program & Font ROM
varies depending on the type of ROM (for the mounting location see 7.2).
Operation Description 2 - 4 OKIPAGE 6e/6ex
Service Manual, P/N 59276401
DRAM
The DRAM is a resident memory (OKIPAGE 6e: 1MB/OKIPAGE 6ex: 2MB) used as a buffer, and
it stores edited data, image data, DLL data and macro data.
EEPROM
1,024 bit-Electrically Erasable PROM (EEPROM), is loaded with the following kinds of data:
Parallel Interface
Parallel data is received from the host system via parallel interface which conforms to the
Centronics specification. IEEE 1284 Bi-directional parallel is supported.
• Menu data
• Various counter data (Page counter, Drum counter)
• Adjusting parameters (LED head drive time, print start position, paper feed length)
