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 repairedas 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 issuggested.

2. TOOLS

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

Tool Remarks

3. CIRCUIT DESCRIPTION

3.1 Outline

The control board controls the reception of data transferred through a host I/F and processes commandanalysis, 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 controlThe 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 processingThe 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 datain such a way that print data are aligned from up to down and from right to left; then it writesthe resultant data into a page buffer with such control data as print position coordinate, fonttype, etc. added.

(3) Font ProcessingWhen one page editing is finished, a developing task makes an engine start and fetches datafrom the page buffer synchronizing with a printing operation; then it developes the fetched datato a bit map as referring to data from a character generator, and writes the resultant data intothe 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 LEDhead.

3.8 Operator Panel Control

The operator panel consists of the following circuits.

1) BU5148S (LSI)

This LSI is connected to a clock synchronous serial port of the CPU. It controls switch data input,LED data output and LCD data input/output according to the commands given by the CPU. TheCPU sends the 2-byte (16-bit) command (SSTXD-P) together with the shift clock signal (SSCLK-N) to the LSI and then makes a predetermined input/output control if the command decodedby the LSI is found to be a normal command.

On receiving a command sent from the CPU, the LSI, synchronizing with the serial clock of thecommand, returns a 2-byte command response to the CPU.

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 tothe LED head starts as synchronized with the page synchronous signal/line synchronous signal (CPUinternal signal).

Bit image data developed on the raster buffer of a memory are DMA-transferred to the register of avideo interface controller (CPU built-in) and then sent to the shift register of the LED head in a serialtransmission 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.

(3) Drive control

Time T0 to T3 determines the motor speed, while the phase different direction between phasesignals 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 thephase 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 referencevoltage. 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 thethermistoris A/D converted in IC2 and the resultant digital value is read and transferred to the CPU. TheCPU turns on or off the HEATON-N signal according to the value of the signal received fromIC2 to keep the temperature at a constant level.

Immediately after the power is turned on, the thermistor is checked for short circuit andbreakdown. If the thermistor is shorted, the A/D converted value shows an abnormally hightemperature, 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 breakdowncan 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 thepredetermined value.

The temperature control is described below.

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.

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

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

Fan motor stop: • The motor immediately stops when an engine error or a fan error occurs.

• The motor stops 20 minutes after the occurrence of a paper jam, size error,or fuse error.

• The motor stops in the power save mode as below.

3.14 Cover Open

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

3.15 Power Supply Board

(1) Low voltage power supplyAn AC power from an inlet is input to a transformer via fuses, AC switch and noise filter andthen lowered to a 28 VAC power and a 10 VAC power. The 28 VAC power is converted toa +30 VDC output through a rectifying/smoothing circuit. A +5 VDC output is derived from theresultant +30 VDC power through a regulation circuit. The 10 VAC power is converted to a +8VDC 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 controlcommand 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 correspondinghigh-voltage generating circuits through pins 12, 13, 14, 15 and 16 of LSI (IC2). It supplies +38Vto each high-voltage generating circuit as the source voltage. When the cover is open, the supplyof +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.

3.16 Option Tray Control

Two kinds of option trays, Second Tray and Multi purpose Feeder, can be connected to the printerindividually 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 synchronizedserial interface. Fig. 3-11 shows its time chart, the printer always sends a command first, then eachoption tray interpret it. Because the command contains an ID, the selected option tray takes appropriateactions, 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 knowsthe timing when it outputs the clock for the reply by sensing OPTSDR-N signal which is turned to zeroby 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 traydetects a signal on OPTPSIN-N signal line, which indicates the paper reaches a input sensor in theprinter, the tray stops the paper feeding after carrying out the paper feeding according to the prede-termined steps which have been downloaded from the printer at power-up time. Fig. 3-12 shows thetime chart.

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