1. OUTLINE

This manual has been written to provide guidance for troubleshooting of the OKIPAGE8p Printer
(primarily for its printed circuit boards), on an assumption that the reader is knowledgeable of the
printer. Read the maintenance manual for this printer if necessary.

Note:

1. High voltage power supply board and power supply unit containing a high voltage power
supply is dangerous. From the viewpoint of the safety standards, the local repairing of a
defective board is not allowed. Thus, the objects to be locally repaired as a result of
troubleshooting are switches.

2. TOOLS

For troubleshooting the printer, the tools listed below may be needed in addition to general
maintenance tools.

Oscilloscope Frequency response 100 MHz or higher

Soldering iron A slender tip type, 15-20 watts

3. CIRCUIT DESCRIPTION

3.1 Outline

The circuit of OKIPAGE8p consists of a main control board, a main high voltage power supply
board, a sub-high voltage power supply board and a power supply unit. The block diagram is
shown in Fig. 3-1. The main control board controls the reception and transmission of data with
a host I/f and processes command analysis, bit image development, raster buffer read. It also
controls the engine and high voltage outputs.

(1) Reception control

The main control board has one parallel I/F port which is compliant to the IEEE 1284
specification.
The parallel I/F port can specify the following item when set by the control panel:

I-PRIME: Enabled/ Disabled

(2) Command analysis processing

The OKIPAGE8p printers support PCL5e (Hewlett Packard LJ6P compatible).
An edit task fetches data from the receive buffer, analizes commands, and reconstructs the
data in such a way that print data are aligned from up to down and from right to left; then it
writes the resultant data into a page buffer with such control data as print position coordinate,
font type, etc. added.

(3) Font Processing

When one page editing is finished, a developing task makes an engine start and fetches data
from the page buffer synchronizing with a printing operation; then it developes the fetched
data to a bit map as referring to data from a character generator, and writes the resultant data
into the raster buffer (of band buffer structure).

(4) Raster buffer read

As controlling the engine operation, an engine task sends data from the raster buffer to the
LED head.

(5) High voltage control (main, sub)

The high voltage control circuit in the CPU.

The high voltage power supply board generates high voltage outputs, and have sensors, LED for
display.
The power supply unit generates +26VDC output, +5DC output.

3.4 EEPROM Control

The BR93LC46A on the main control board is an electrical erasable/programmable ROM of 64­bit x 16-bit configuration. Data input to and output from the ROM are bidirectionally transferred
in units of 16 bits through I/O port (EEPRMDT-P) in serial transmission synchronized with a clock
signal from the CPU.

The EEPROM operates in the following instruction modes.

3.5 Centronics Parallel Interface

The CPU sets a BUSY-P signal to ON at the same time when it reads the parallel data (PDATA1­P to PDATA 8-P) from the parallel port at the fall of PSTB-N signal. Furthermore, it makes the store
processing of received data into a receive buffer terminate within a certain fixed time and outputs
an ACK-N signal, setting the BUSY-P signal to OFF.

3.7 LED Head Control

An LED correcting head, which is capable of correcting the illumination of the LED for each dot,
is being used in this printer. LED illumination correction function of 16 steps is carried out by using
an EEPROM which is installed in the LSI that maintains the LED illumination correction values,
and an LED correction drivers (MSM6731BWAF or MSM6732BWAF) together as a pair.

The LED correcting head consists of the correction control LSI (MSM6730WAF), LED drivers
(MSM6731BWAF or MSM6732BWAF), and an LED array.

First line printing

The printing operation is carried out in the following sequence. First, the printing data DATAI3
through DATAI0 are stored, sequentially shifted, in the shift registers of the LED drivers, by the
printing data synchronous clock, CLOCKI. Then the printing data stored in shift registers are
latched by the high level pulse of LOADI. The latched printing data turns the LEDs on by STRB1I­N through STRB4I-N and actuates printing.

(2) Motor drive control

Time T0 to T3 determines the motor speed, while the phase different direction between
phase signals DMPH1-P and DMPH2-P determines the rotation direction. DMON-N signal
control a motor coil current. According to the polarity of the phase signal, the coil current flow
as follows:

1) +26V → SW1 → motor coil → SW4 → resistor → earth

2) +26V → SW3 → motor coil → SW2 → resistor → earth
The drop voltage across the resistor is input to comparator, where it is compared with a

reference voltage. If an overcurrent flows, a limiter operates to maintain it within a certain
fixed current.

(3) Electromagnetic clutch control

Mechanical operation mode is switched by the combination of the clutch status and the
direction of motor rotation.

3.9 Fuser Temperature Control

For the temperature control by heater control, the variation in the resistance of the thermistor is
A/D converted in LSI and the resultant digital value is read and transferred to the CPU. The CPU
turns on or off the HTON-N signal according to the value of the signal received from LSI to keep
the temperature at a constant level.
Immediately after the power is turned on, the thermistor is checked for shortcircuit and
breakdown. If the thermistor is shorted, the A/D converted value shows an abnormally high
temperature, so that the shortcircuit can be detected. If the breakdown of the thermistor occurs,
the A/D converted value shows the normal temperature. In this case, the thermistor breakdown
can be detected by the sequence shown at the end of this section. If the heater is overheated,
5V supply is turned off when the resistance of the thermistor is detected to be exceeding the
predetermined value.

3.11 Cover Open

When the cover is opened, a cover open microswitch is opened. This makes a CVOPN-N signal
low, thereby the CPU detects that cover is open. Furthermore, opening the cover stops applying
a +5V power to the high voltage power supply part, resulting in stopping all high voltage outputs.
