Page 14: Main Control Board (Pcr Pcb)
Page: 8 Service Guide - OKIPAGE 8c Chapter 2 Operation 2.1 Main Control Board (PCR PCB) The control board consists of a CPU (NR4700) block, a memory control LSI block, an interface control LSI block, a DRAM block, an EEPROM block, a mask ROM block, and an interface block.
Page 16 Functional Block Diagram of Main Control Board The CPU is a 64-bit RISC architecture processor (provided y NKK). It inputs a frequency of 50 MHz and runs at 100 MHz. It transfers data to a from memory at 50 MHz. Mask ROM The mask ROM block consists of four 16 Mbit (1M x 16 bits) chips and its total size is 8M bytes.
Page 17 Host interface The printer has the following interfaces to the host. Centronics bi-directional parallel 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 as not to cause interface time-out at the host side.

Page 26: Electrophotographic Processing Mechanism
Page: 12 Service Guide - OKIPAGE 8c Chapter 2 Operation 2.4.1 Electrophotographic processing mechanism Electrophotographic processed - Each process of the electrophotographic processing mechanism is outlined below. (1) Paper pickup - This process causes the roller to give a DC voltage to the paper, resulting in a negative charge.
Page 27 A DC voltage (0V to 2KV) is applied to the driven roller A, to create a positive charge on the lower surface of the paper. The kept in charged paper is electrostatically attracted to the pickup roller. The paper is in close contact with the conveying Belt and moves steadily.
Page 28 (2) The toner blade scrapes away excess toner from the developing roller, leaving a thin film of toner on the surface of the developing roller. (3) The toner is attracted to the latent image on the surface of the image drum, where the image drum contacts the developing roller.
Page 29 (8) Cleaning - The toner which remains on the (OPC) Image Drum without being fused is scraped by a cleaning blade and discarded in the waste toner tank.

Page: 13 Service Guide - OKIPAGE 8c Chapter 2 Operation 2.4.2 Paper running process How paper moves through the OKIPAGE 8c is shown in the Paper Route Diagram. Y=Yellow; M=Magenta; C=Cyan; K=Black...
Page 32 (1) Paper hopping and transfer and up/down movement of pinch roller 2 Paper is hopped and delivered by the mechanism shown below. This mechanism is driven by a single pulse motor. The pulse motor turns in the arrow direction (a) and drives the hopping roller in the direction of "b". The hopping roller drives the resist roller.
Page 33 b) Conveying (1) After paper hopping is completed, the pulse motor turns right (in the direction of "b") to drive the resist rollers 1 and 2. The resist rollers feed the paper until the Form sensor turns on. Although the one-way gear A is also driven, the hopping roller does not turn because of the one-way clutch.
Page 34 (2) The hopping operation of the front feeder and the up/down operation of the pinch roller 2 are performed by a single pulse motor.
Page 35 When the pulse motor of the front feeder turns right (in the direction of "A"), the front hopping roller turns left (in the direction of "b") to drive the cam. This cam moves up an down the pinch roller 2. The one-way clutch gears are made to turn only in a present direction by means of the one-way clutches.
Page 36 (b) Front feeding hopping (1) The pulse motor of the front feeder turns right (in the direction of "a") to drive the hopping roller. The paper feeds until the Entrance sensor 2 is activated. Although the one-way clutch gear B is also rotating, the pinch roller 2 does not drive the up/down cam (because of the one-way clutch).
Page 37 (c) Conveying (1) After paper hopping is completed, the pulse motor turns right (in the direction of "b") to drive the resist rollers 1 and 2. The resist rollers feed the paper until the Form sensor turns on. (2) Although the one-way gear A is also driven, the first hoping roller does not turn (because of the one-way clutch).
Page 38 (2) Up/down movement of the image drum unit and rotation of the image drum. The up/down movement of the image drum unit and the rotation of the image drum are performed by a mechanism shown below. (See Figure 2.6-a). This mechanism is driven by a single pulse motor.
Page 39 Upward Movement of Image Drum Downward Movement of Image Drum (3) Lubrication and cleaning of fixing, ejecting, and heat rollers.
Page 40 The fixing roller, the ejecting roller, and the heat roller are lubricated and cleaned by a single pulse motor. When the heat roller pulse motor turns right (in the direction of "a"), the heat roller and the backup roller turn left (in the direction of "a") to fix a toner image onto the paper. At the same time, three ejection rollers turn right (in the direction of "a") to eject the paper.

Page 46: Transfer Control According To Environmental Changes
Transfer Control according to Environmental Changes Room Temperatures and Relative Humidities) OKIPAGE 8c measures the room temperature and humidity. It uses a room temperature sensor and a room humidity sensor. An optimum transfer voltage is calculated, using the obtained environmental conditions.
Page 47: Form Jam Detection
Chapter 2 Operation 2.8 Form Jam Detection OKIPAGE 8c checks for a paper jam when the page printer is powered on, and during printing. When a paper jam is found, the OKIPAGE 8c immediately stops the printing process. To recover the printer, open the cover, find and remove the jammed paper, then close the cover.
Page 48: Cover Opening
2.9 Cover Opening When the upper, side, or front cover of the OKIPAGE 8c is opened, the Cover open microswitch turns off, the voltage of 32V to the high-voltage power supply is shit off, and all high-voltage outputs are shut off.
