1. OUTLINE

This manual has been written to provide guidance for troubleshooting of the OKIPAGE 10e Printer (primarily for its printed circuit boards), based on the assumption that the reader has a thorough knowledge concerning the printer. Read the maintenance manual for this printer, if necessary.

Notes:

1. The power supply board 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. Replacement of CPU (MHM2029) is not recommended. If CPU is found to be defective, board replacement is suggested.

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 main control board controls the reception of data transferred through a host I/F and processes command analysis, bit image development, raster buffer read. It also controls the engine and the operator panel. Its block diagram is shown in Fig. 3-1 .

(1) Reception control

The OKIPAGE 10e Printer can be equipped with one I/F port by adding an RS232C I/F option board in addition to the Centronics I/F on the main control board. Either of the two I/F ports which receives data first can be used automatically. The other I/F port outputs a busy state signal. The parallel I/F port can specify the following item when set by the control panel:

I-PRIME: Enabled/Disabled

The serial I/F port can specify the following item when set by the control panel:

Flow control : DTRHI/DTR LO/XONXOFF/RBSTXON Baud rate : 300/600/1200/2400/4800/9600/19200 (Baud) Data bit : 7/8 (bits) Minimum busy time : 200/1000 (ms) Parity : NONE/ODD/EVEN

An interface task stores all data received from the host into a receive buffer first.

(2) Command analysis processing

The OKIPAGE 10e Printer support PCL6 (Hewlett Packard LJ6P compatible). An edit task fetches data from the receive buffer, analyzes 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.

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

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 of a memory 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 HDCLK-P signal.

When 1-dot line data (2496 bits) is completely shifted, it is latched by means of the HDLD-P signal, causing LEDs to be driven by means of the STB1-N to STB4-N signals in 4-time division.

Time T0 to T3 determines the motor speed, while the difference of phase direction between phase signals DMPH1-P and DMPH2-P (RMPH1-P and RMPH2-P) determines the rotation direction. DMON1-N and RMON-N signals control a motor coil current. According to the polarity of the phase signal, the coil current flow as follows:

1) +38V → SW → motor coil → SW → resistor → earth, or,

2) +38V → SW → motor coil → SW → resistor → earth The voltage drop across the resistor is input to comparator, where it is compared with a

reference voltage. If an overcurrent flow occurs, a limiter operates to maintain it within a certain fixed amount of current.

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 IC2 and the resultant digital value is read and transferred to the CPU. The CPU turns on or off the HEATON-N signal according to the value of the signal received from IC2 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.

* The values V1 and V2 vary according to setting mode.

(Standard temperature)

When Vt rises to V2 or more, the heater is turned off (by setting HEATON-N signal to LOW). When Vt drops to V1 or less, the heater is turned on (by setting HEATON-N signal to HIGH). In this way, the temperature can be kept within the predetermined range.

41266201TH Rev.1 21 /

For heater breakdown detection, the heater must first be turned on. When a temperature rise which corresponds to the switching on of the heater does not occur, then a heater breakdown is detected. To shorten the breakdown detection time, the following circuit is used. Immediately after the power is turned on, the thermistor is checked and THERM-CMP signal is turned on to turn the resistor Q44 on. The reading resolution is increased through the variation of the thermistor resistance value.

If, for whatever reason, temperature control fails and the temperature rises abnormally, the abnormal high temperature detection circuit shown below forcibly cuts the power supply to the fuser.

(1) Low voltage power supply

An AC power from an inlet is input to a transformer via fuses, AC switch and noise filter and then lowered to a 32 VAC power and a 10 VAC power. The 32 VAC power is converted to a +38 VDC output through a rectifying/smoothing circuit. A +5 VDC output is derived from the resultant +38 VDC power through a regulation circuit. The 10 VAC power is converted to a +8 VDC output and a -8 VDC output through a rectifying/smoothing circuit.

(4) High-voltage power supply circuit

This high-voltage power supply circuit receives the high-voltage generation timing control command that is transmitted in serial through the power supply interface from the control section. It decodes this command by LSI (IC2) and outputs high-frequency pulses to the corresponding high-voltage generating circuits through pins 11, 12, 13, 14 and 15 of LSI (IC2). It supplies +5V to each high-voltage generating circuit as the source voltage. When the cover is open, the supply of +5V is interrupted to interrupt all the high-voltage outputs. The relationship between the high-frequency pulse output pins and the high-voltage outputs is shown in the following table.

3.13 Option Tray Control

The kinds of option trays, High capacity Second Paper Feeder and Multi purpose Feeder can be connected to the printer. The trays are distinguished by two digit ID numbers.

The option trays and the printer communicate with each other through bi-directional clock synchoronized serial interface. The printer always sends a command first, then each option tray interpret it. Because the command contains an ID, the selectes option tray takes approriate actions, then sends back a reply. The command and reply are transmitted back and forth on OPTSD-P signal line by synchronizing OPTSCLK-N clock signal which is sent by the printer. The printer knows the timing when it outputs the clock for the reply by sensing OPTSDR-N signal which is turned to zero by the option tray when it is ready for the reply.

The option tray’s paper feeding action is triggered by a command sent by the printer. When the tray delects a signal on OPTPSIN-N signal line, which indicates the paper reaches a input sensor in the printer, the tray stops the paper feeding after carrying out the paper feeding according to the predetermined steps which have been downloaded from the printer at power-up time.

Status of the option trays such as no paper cassette, paper out and cover open, are informed to the printer though a reply in response to a status inquiry command.
