  • Page 13 OPERATION DESCRIPTION The OKIPAGE 8p/8w consists of a main control board, a high-voltage power supply board, a power supply unit, and an electro-photographic processor. The OKIPAGE 8p/8w receives print data from a higher-level interface and sequentially stores it in memory. The OKIPAGE 8p/8w decodes and edits the received data while storing print data from the interface in memory.

  • Page 15: Main Control Board

    LED head, a main motor, and an electromagnetic clutch. (1) One-chip CPU • OKIPAGE 8p The one-chip CPU is a custom CPU (32-bit internal bus, 16-bit external bus, 28-MHz clock). This CPU has the functions listed in the table below.
  • Page 16 (2) Program ROM Program ROM contains a program for the equipment. EPROM is used as program ROM. When mask ROM in the one-chip CPU explained in (1) above is valid, the EPROM is not mounted. (For details on short wiring setting, see Section 7.2.) (3) DRAM DRAM is used as resident memory.
  • Page 17: Power Supply Unit

    Power Supply Unit The power supply unit supplies +5 V and +26 V to the main control board according to 230 VAC / 120 VAC. Output voltage Application +5 V Used to generate a logic circuit and a high voltage. +26V Used to drive the motor and electromagnetic clutch.
  • Page 18 (2) Sensors The high-voltage power supply board consists of the high-voltage power supply circuit that supplies power to the electro-photographic processor system and the photosensor that detects a paper feeding system and toners. Figure 2-2 shows the sensor layout drawing. Exit roller Outlet sensor Heat roller...
  • Page 19: Electro-Photographic Processor

    Electro-Photographic Processor The electro-photographic processor prints out the image data to be sent from the main control board on sheets of paper. Figure 2-3 shows the layout drawing of the electro-photographic processor. (1) Image drum unit The image drum unit makes a toner adhere to the formed electrostatic latent image with static electricity.
  • Page 20 2 - 8...
  • Page 21 (3) Pulse motor (Main) This pulse motor of 48 steps/rotation is two-phase excited by the signal from the main control board; it performs feeding control by switching normal rotation to reverse rotation or vice versa and turning on/off the electromagnetic clutch. The relationship between the main motor, electromagnetic clutch, resist gear, drum gear, hopping roller is shown in the table below and on the subsequent pages.

  • Page 23: Electro-Photographic Process

    Electro-Photographic Process (1) Electro-photographic process The electro-photographic process is outlined below. 1 Charging The surface of the OPC drum is charged negatively and uniformly by applying the DC voltage to the CH roller. 2 Exposure Light emitted from the LED head irradiates the negatively charged surface of the OPC drum.

  • Page 27 (3) Charging Charging is performed by applying DC voltage to the charge roller that is in contact with the surface of the OPC drum. High- voltage Charge roller power supply OPC drum (4) Exposure Light emitted from the LED head irradiates the negatively charged surface of the OPC drum. The surface potential of the irradiated surface attenuates to form the electrostatic latent image corresponding to the image signal.
  • Page 28 (5) Development The electrostatic latent image on the surface of the OPC drum is changed to a visible toner image by applying a toner to it. Development is performed in the contact part between the OPC drum and developing roller. 1 The sponge roller negatively charges a toner and applies it to the developing roller.
  • Page 29 (6) Transfer The transfer roller is composed of conductive sponge material. This roller is set so that the surface of the OPC drum and sheets of paper will adhere closely. A sheet of paper is placed on the surface of the OPC drum and the positive charge opposite to the negative charge of a toner is applied from the reverse side by the transfer roller.
  • Page 30 (7) Fusing The transferred unfused toner image is fused to a sheet of paper because heat and pressure are applied when it passes between the heat roller and back-up roller. The Teflon-coated heat roller contains a 400 W heater (Halogen lamp) that heats the heat roller.
  • Page 31: Paper Jam Detection

    Paper Jam Detection The OKIPAGE 8p/8w monitors the paper status when the power supply is on and during printing. In the following cases, the OKIPAGE 8p/8w interrupts the printing process as a paper jam. Printing can be recovered by opening the cover, removing the jammed paper, and closing the cover.

    (2) The basic rotation cycle of the toner sensor is as follows: T time Basic rotation cycle of toner sensor 2.5 sec. Toner low time t1 > 0.6 sec. Toner full time 0.6 sec. > t1 > 0.14 sec. Cover Open Opening the stacker cover turns off the microswitch on the high-voltage power supply board to suspend +5 V supply to the high voltage power supply.
  • Page 35: Detecting Id Existence

    Detecting ID existence In this model, a micro switch may be activated, applying a high voltage to the machine under a state where the cover is slightly opened. In this case, there is a fear that, when a user insert his hand through the opening, he may be shocked unless an ID has been installed.

    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: High voltage power supply board and power supply unit containing a high voltage power supply is dangerous.
  • Page 130: Circuit Description

    CIRCUIT DESCRIPTION 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.

    EEPROM Control The BR93LC46A on the main control board is an electrical erasable/programmable ROM of 64- bit 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.
  • Page 136: Centronics Parallel Interface

    Centronics Parallel Interface The CPU sets a BUSY-P signal to ON at the same time when it reads the parallel data (PDATA1- P 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.

    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.
