Chapter 2 Operation
Operation Description
OKIPAGE 10e 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.
OKIPAGE 10e block diagram is shown in Figure 2-1.

Chapter 2 Operation
2.1 Main Control Board
The main control board consists of a single chip CPU, two program/font ROMs, four DRAMs, an EEPROM, a host
interface circuit, and a mechanism driving circuit.
(1) Single chip CPU
The single chip CPU is a custom CPU (32-bit internal bus, 32-bit external bus, 28.24-MHz clock, with input frequency
from a 7.06-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.
Serial interface controller Control of RS-232C serial interface.
Video output port
Controls LED head.
LED STB output port
Timer Generation of various control timing
Monitoring of paper running and paper size.
I/O Port Input and output of sensor and motor signals.
(2) Program and Font ROMs
The Program and Font ROMs store the equipment program and various types of fonts. Mask ROM is used as Program
and Font ROMs. The mounting locations of these Program and Font ROMs vary depending on the type of the ROMs.
(3) DRAM
The DRAM is a 4MB resident memory on the main control board that stores edited data, image data, DLL data and
macro data.
(4) EEPROM
4Kbit Electrically Erasable PROM (EEPROM), is loaded with the following kinds of data:
Menu datal
Various counter data (page counter, drum counter)l
Adjusting parameters (LED head drive time, print start position, paper feed length)l
(5) Parallel Interface
Parallel data is received from a host system via parallel interface which conforms to the IEEE 1284 specification.

Chapter 2 Operation
2.2 Power Supply/Sensor Board
The power supply/sensor board consists of an AC filter circuit, a low voltage power supply circuit, a high voltage power
supply circuit, heater drive circuit, and photosensors.
(1) Low Voltage Power Supply Circuit
This circuit generates the following voltages.
Output voltage Application
+5 V Logic circuit supply voltage.
+38 V Motor and fan drive voltage and source voltage for high-voltage supply.
+ 8 V RS-232C line voltage.
- 8 V RS-232C line voltage and PS board supply voltage.
(2) High Voltage Power Supply Circuit
This circuit generates the following voltages required for electrophotographic process from +5 V, according to the control
sequence from the main control board. When cover open state is detected, +5 V supply is interrupted automatically to
stop the supply of all high-voltage outputs.
Output Voltage Application
CH -1.3 KV Voltage to be applied to charge roller.
DB -265 V/+300 V Voltage to be applied to a developing roller.
SB -500 V/ 0 V Voltage to be applied to a sponge roller.
CB +400 V/+3.5 KV Voltage to be applied to a cleaning roller.
TR +500 V to +3.5 KV/-1100 V Voltage to be applied to a transfer roller. (Variable)
(3) Photosensor
The photosensor mounted on this power supply/sensor board monitors the status of paper being fed through the printer
during printing.
The sensor layout diagram is shown in Figure 2-2 below.
Figure 2-2
Sensor Function Sensing State
Inlet sensor 1 Detects the leading part of the paper and gives the
monitor timing for switching from hopping operation
to feeding operation. Monitors paper feeding
situation and paper size based on the paper arrival
time and running time.
Inlet sensor 2 Detects the paper width. ON: A4 or larger.
Paper sensor Detects the leading portion of the paper. Monitors
paper feeding situation.
Output sensor Monitors paper feeding and size according to the
time of arrival to and leaving past the sensor.
ON: Paper exists.
OFF: No paper exists.
OFF: Smaller than A4.
ON: Paper exists.
OFF: No paper exists.
ON: Paper exists.
OFF: No paper exists.
Toner sensor Detects the lack of toner. - - - - -
