1. OUTLINE

This manual has been written to provide guidance for troubleshooting of the OKIPAGE 6e Series 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.

Notes:

1. The power supply board (OLER/OLHR) 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 (MHM2029K) 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 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 through 3-4.

(1) Reception control

The control board has one centronics parallel I/F port. 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 OKIPAGE 6e series printers have the following emulation modes.

Laser Jet Series IVP : Hewlett Packard OKIPAGE 6e/6ex

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.

3.6 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.

3.9 LED Head Control

(1) For OKIPAGE 6e 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 by the HDDTO-P signal.

When 1-dot line data (2560 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.

(2) For OKIPAGE 6ex

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 together as a pair.

The LED correcting head consists of the correction control LSI, LED drivers, and an LED array.

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 STRB1I-N through STRB4I-N and actuates printing.

Time T0 to T3 determines the motor speed, while the phase different direction between phase signals DMPH1-P and DMPH2-P (RMPH1-P and RMHPH2-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) +30V → SW → motor coil → SW → resistor → earth, or,

2) +30V → SW → motor coil → SW → 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.

3.11 Fuser Temperature Control

For the temperature control by heater control, the variation in the resistance of thethermistor 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 short circuit and breakdown. If the thermistor is shorted, the A/D converted value shows an abnormally high temperature, so that the short circuit can be detected. If the breakdown of the thermistor occurs, the A/D converter 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 t o setting mode.

(Standard temperature)

When Vt rises to V2 or more, the heater is turned of (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.

- 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 THERMCMP signal is turned on to turn the transistor 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.

The 28 VAC power is converted to a +30 VDC output through a rectifying/smoothing circuit. A +5 VDC output is derived from the resultant +30 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.

(3) High voltage power supply

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 12, 13, 14, 15 and 16 of LSI (IC2). It supplies +38V 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 highfrequency pulse output pins and the high voltage outputs is shown in the following table.

3.16 Option Tray Control

Two kinds of option trays, Second Tray and Multi purpose Feeder, can be connected to the printer individually or at same time by daisy chain. The trays are distinguished by two digit ID numbers. Fig. 3-10 shows the connection and the block diagrams.

The option trays and the printer communicate with each other through bi-directional clock synchronized serial interface. Fig. 3-11 shows its time chart, the printer always sends a command first, then each option tray interpret it. Because the command contains an ID, the selected option tray takes appropriate actions, then sends back a reply. The command and reply are transmitted back and forth on OPTSDP 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 detects 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. Fig. 3-12 shows the time chart.

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.
