  • Page 27: Main Control Board (Board-Fff)

    Page: 11 Service Guide OKIPAGE 18/18n Chapter 2 Operation Description 2.1 Main Control Board (BOARD-FFF) The main control board consists of a one-chip CPU, LSI, program/font ROM's, DRAM's, EEPROM, host interface circuit, and a mechanism driving circuit. (1) One-chip CPU The one-chip CPU is a custom CPU (32-bit internal bus, 32-bit external bus, 120-MHz clock) that incorporates an RISC CPU and its peripheral devices, and has the following functions.
  • Page 28 Centronics bidirectional parallel interface RS232C interface OKI HSP interface (Option) The single effective interface or the automatic interface select mode can be selected using the menu. If the busy state of the printer continues for a long time period, the buffer near-full control releases the busy status at constant intervals even if the host side is busy so not to cause the interface time-out at the host side.
  • Page 29 (For the electrical/ physical characteristics of the interface, see APPENDIX B) (c) OKI HSP interface (Option) This interface (slot) is an OKI unique universal interface that provides the platform to connect option boards (including those supplied by third party venders) such as the LAN connection expansion board and SCSI expansion board.

  • Page 40 Page: 16 Service Guide OKIPAGE 18/18n Chapter 2 Operation Description 2.3.3 Process operation descriptions (1) Hopping Hoppings from the first tray and the front feeder are effected by a single hopping motor in the mechanism shown below. Turning the Hopping motor in direction a (CW) drives the 1st Hopping Roller. Turning the Hopping motor in direction b (CCW) drives the Front Hopping Roller.
  • Page 41 (a) Hopping from the 1st Tray 1 Hopping Rotating the Hopping Motor in direction a (CW) drives the 1st Hopping Roller and the Sub Roller then pick up a sheet of paper in the 1st tray. The Main Motor is always driven in direction c (CCW) on printing. After the paper is fed approx.
  • Page 42 Roller idles freely by escaping the Planet Gear. 5 Printing starts after the paper turns off the Write Sensor. (b) Hopping from the Front Feeder 1 Hopping The Front Feeder Plate is normally locked at the lower position by the Release Lever activating the Micro Switch. The top of the FF Cam which is attached to the end of the Front Hopping Shaft is normally located in the upper position (0 to 30 degree : home position).
  • Page 43 5 Printing starts after the paper turns off the Write Sensor.
  • Page 44 (2) Feeding After finishing hopping, the pulse motor dedicated for driving the registration roller rotates to drive the registration roller. The registration roller advances the paper until it comes out of the registration roller. When the leading edge of the paper causes the paper sensor to turn on, the printing is started synchronously. Although Gear D is always rotating due to an all-time rotation of the main motor in direction c, the registration roller...
  • Page 45 would not rotate because the clutch (registration) is turned off. After completion of hopping, turn on the clutch (registration) to drive the registration roller. The registration roller will drive the paper until the paper has passed. (3) Charging Charging is effected by applying a DC minus voltage to the charge roller that is in contact with the image drum surface.
  • Page 46 1 As the toner supply roller rotates while rubbing on the developing roller, a friction charge is generated between the developing roller and the toner, allowing the toner to be attracted to the developing roller. (The developing roller surface is charged positive and the toner, negative.) 2 The toner attracted to the developing roller is scraped off by the doctor blade, forming a thin coat of toner on the developing roller surface.
  • Page 47 (7) Fusing After the end of the transfer, the unfused toner image is fused on the paper under heat and pressure as it passes between the heater roller and the back-up roller. The heater roller with a Teflon coating incorporates a 750W heater (Halogen lamp), which heats the heat roller.

  • Page 49 The block diagram of the LED correcting head is shown below. (1) Both sides wire-bonding head In OKIPAGE 18/18n, the correction control of LED head is executed directly by the CPU. The procedure is as follows (i) LED head is set to the correction control read mode and all correction data stored in EEPROM within the correction control LSI are read by CPU, and stored temporarily in the memory.

  • Page 51 (i) LED head is set to the correction control read mode and all correction data stored in EEPROM within the correction control LSI are read by CPU, and stored temporarily in the memory. (ii) Next, LED head is set to the correction control direct mode and the correction data stored temporarily in the memory is transferred directly to the LED driver.
  • Page 52 (ii) Transfer of correction data to head driver correction data The LED driver corrects the LED illumination by controlling the LED current. The LED illumination can be set in 16 steps, with 7 steps in the direction of illumination increase in relation to the standard value, and 8 steps in the direction of decrease.
