Page 26: Operation
Service Manual for OKIPAGE 14ex Page: 11 Chapter 2 Operation Operation Description OKIPAGE 14ex consists of a main control board, a power supply/sensor board, an operator panel, an electrophotographic process mechanism, and revision for illumination of LED head. The main control board receives data via the host I/F, it then decodes, edits and stores the data in memory. After completing the editing of a single page of data, it references the font memory and generates bit image data, which is transferred to the LED head in one dot line units.
Page 29: Main Control Board
Service Manual for OKIPAGE 14ex Page: 12 Chapter 2 Operation 2.1 Main Control Board The main control board consists of a single chip CPU, two program/font ROMs, four DRAMs, an EEPROM, a host interface circuit, and a mechanism driving circuit. (1) Single chip CPU The single chip CPU is a custom CPU (32-bit internal bus, 32-bit external bus, 32-bit external bus, 49.766-MHz clock, which incorporates the RISC CPU and its peripheral devices, and has the following functions:...

Service Manual for OKIPAGE 14ex Page: 16 Chapter 2 Operation 2.3.2 Electrophotographic Process The electrophotographic processing is outlined below. The electrophotographic printing process is shown in Figure 2-4 (see below). 1 Charging The surface of the image drum is charged uniformly with a negative charge by applying the negative voltage to the charge roller. 2 Exposure Light emitted from the LED head irradiates the negatively charged surface of the image drum.

Page 43: Process Operation Descriptions
Service Manual for OKIPAGE 14ex Page: 17 Chapter 2 Operation 2.3.3 Process Operation Descriptions (1) Hopping and Feeding Hopping and feeding motions are actuated by a single registration motor in the mechanism as shown below: The registration motor turning in direction "a" drives the hopping roller. The registration motor turning in direction "b" drives the registration roller. The registration and hopping gears have one-way bearing, so turning any of these gears in the reverse direction will not transmit the motion to the corresponding roller.
Page 44 (b) Feeding 1 When hopping is completed, the registration motor turning in direction "b" (counter-clockwise direction) drives the registration roller to advance the paper (in this case, the hopping gear also turns, but the hopping roller is prevented from turning by the one-way bearing). 2 The paper is further advanced in synchronization with the print data.
Page 45 (2) Charging Charging is actuated by the application of the DC voltage to the charge roller that is in contact with the image drum surface. The charge roller is composed of two layers, a conductive layer and a surface protective layer, both having elasticity to secure good contact with the image drum. When the DC voltage applied by the power supply exceeds the threshold value, charging begins.
Page 46 forming an electrostatic latent image associated with the image signal. The image drum is coated with an underlayer (UL), a carrier generation layer (CGL), and carrier transfer layer (CTL) on aluminum base. The organic photo conductor layer (OPC), comprising CTL and CGL, is about 20 mm thick. The image roller surface is charged to about -750 V by the contact charge of the charge roller.
Page 47 The positive carriers moved to the CTL combine with the negative charges on the image drum surface accumulated by the contact charge of the charge roller, lowering the potential on the image drum surface. The resultant drop in the potential of the irradiated portion of the image drum surface forms an electrostatic latent image on it.
Page 48 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. 3 Toner is attracted to the exposed portion (low-potential part) of the image drum at the contact of the image drum and the developing roller, making the electrostatic latent image visible.
Page 49 (5) Transfer The transfer roller is composed of conductive sponge material, and is designed to get the image drum surface and the paper in a close contact. Paper is placed over the image drum surface, and the positive charge, opposite in polarity to that of the toner, is applied to the paper from the reverse side. The application of a high positive voltage from the power supply to the transfer roller causes the positive charge inducement on the transfer roller surface, transferring the charge to the paper as it contacts the transfer roller.
Page 50 (6) Fusing When the transfer is completed, the toner image is fused to the paper by heat and pressure as the paper with unfused toner image passes between the heater roller and the back-up roller. The heater roller with Teflon coating incorporates a 400W heater (Halogen lamp), which generates heat. A thermistor which is in contact with the heater roller regulates the temperature of the heater roller to a designated temperature in the menu, depending on the thickness of the paper (tray 1&2: light=165°C, medium light=170°C, medium=175°C, medium heavy and heavy=195°C/manual feeding and power envelope feeder: light=175°C, medium light=180°C, medium=185°C, medium heavy=190°C, heavy=195°C, transparency = 160°C).
Page 51 (7) Cleaning When the transfer is completed, the residual toner left on the image drum is attracted to the cleaning roller temporarily by static electricity, and the image drum surface is cleaned.
Page 52 Changes in bias voltage applied to each roller move the attaching toner off the roller to the image drum and return it to the developer. Copyright 2000, Oki Data, Division of OKI America, Inc. All rights reserved. See the Oki Data Business Partner Exchange...
Page 53: Revision Of Led Head Illumination
Service Manual for OKIPAGE 14ex Page: 18 Chapter 2 Operation 2.3.4 Revision of LED Head Illumination 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.

Page 59: Toner Low Detection
Service Manual for OKIPAGE 14ex Page: 21 Chapter 2 Operation 2.6 Toner Low Detection Device The Toner Low Detection device consists of a stirring gear which rotates at a constant rate, a stirring bar and a magnet on the stirring bar. The stirring bar rotation is driven by the link to the protrusion in the stirring gear.
Page 60 Operation during Toner Low state When the stirring bar reaches the maximum height, it falls to the minimum height due to its own weight, since there is no resistance provided by the toner on the other side. Because of this, the time interval during which it is in encounter with the magnet of the sensor lever becomes longer. By monitoring this time interval, Toner Low can be detected.
