1. OUTLINE

This manual has been written to provide guidance for troubleshooting of the OKIPAGE4w Plus 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 P/N M-521426 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 and fuses.

2. TOOLS

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

3. CIRCUIT DESCRIPTION

3.1 Outline

The circuit of OKIPAGE4w Plus consists of a main control board, a 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 and transmission control

The main control board has one parallel I/F port which is compliant to the IEEE 1284 specification. An interface task stores all data received from the host into a receive buffer first, and returns the printer status upon request of the host.

(2) Command analysis processing

The OKIPAGE4w Plus printer has the following emulation mode.

Hiper-W: OKI original

An edit task fetches data from the receive buffer, analizes commands, and sets I/O registers.

(3) Raster data processing

The decompression circuit in the CPU expands the compressed data and stores the data into the raster buffer.

(4) Raster data transfer

The LED head control circuit in the CPU sends the data stored in the raster buffer to the LED head.

(5) High voltage control

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 +24VDC output, +5DC output.

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

When a paper form is made to arrive at the data write position on print start, the sending of data to the LED head starts as synchronized with the page synchronous signal/line synchronous signal (CPU internal signal).

Bit image data developed on the raster buffer in the CPU are DMA-transferred to the register of a video interface controller (CPU built-in) and then sent to the shift register of the LED head in a serial transmission synchronized with the VCLK-P signal by the VD0-P signal.

When 1-dot line data (2560 bits) is completely shifted, it is latched by means of the VLD-P signal, causing LEDs to be driven by the VSTB1-N through VSTB4-N signals in different timing for each signal.

Some of LED heads have 2496 dots rather than 2560 dots. The controls regarding the number of dots are adjusted to the LED head installed when the printer is shipped from the factory.

(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-P signal control a motor coil current. According to the polarity of the phase signal, the coil current flow as follows:

1) +24V → SW1 → motor coil → SW4 → resistor → earth, or,

2) +24V → 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

The temperature change in a heat controller is converted into the electric potential TEMP corresponding to the change in the resistance value of a thermistor, and the resultant potential is fed back to the control circuit. The CPU performs ON/OFF control of the HEATON-P signal to keep the heat roller temperature constant in accordance with the state at which the thermistor voltage (TEMP) is read into directly by the AD converter of the CPU. THCHK-N signal is fixed to “0”. When the paper thickness is set on the menu of the host, the temperature is adjusted to the targeted thickness accordingly.

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.
