Page 60: Hopping
Page: 50 Service Guide OF1000 Chapter 2 Principles of Operation 2.5.02 Hopping Hopping loads paper from the paper cassette. During the hopping operation, the registration motor turns in a clockwise direction. This motor drives the hopping roller, which in turn advances the paper until the inlet sensor 1 switches ON.
Page 61: Feeding
Page: 51 Service Guide OF1000 Chapter 2 Principles of Operation 2.5.03 Feeding Feeding transports paper through the printer. After the completion of hopping, the registration motor turns in a counter-clockwise direction. This counter-clockwise motion drives the registration roller and advances the paper. The hopping gear turns, but the one-way bearing does not allow the hopping roller to turn.
Page 62: Charging
Page: 52 Service Guide OF1000 Chapter 2 Principles of Operation 2.5.04 Charging Charging applies -1.3 Kvdc to the charge roller. The charge roller contacts the image drum surface. The charge roller has two layers: a conductive layer and a surface protective layer. The surface layer is flexible, which assures proper contact with the photosensitive drum.
Page 63: Exposing
Page: 53 Service Guide OF1000 Chapter 2 Principles of Operation 2.5.05 Exposing The image drum has four layers. · Carrier Transfer Layer (CTL) · Carrier Generation Layer (CGL) · Underlayer (UL) · Aluminum Base The CTL and CGL make up the organic photo conductor layer (OPC), which is about 20 micrometers (m m) thick.
Page 64 (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 part of the image drum surface forms an electrostatic latent image on it. The surface potential on this irradiated part of the image drum is approximately -100 vdc.
Page 65: Developing
Page: 54 Service Guide OF1000 Chapter 2 Principles of Operation 2.5.06 Developing The electrostatic latent image formed on the image drum surface is developed into a visible image. Developing takes place when contact is made between the image drum and the developing roller.
Page 66 NOTE: The toner supply roller and the developing roller are supplied with the bias voltages required during the developing process. The toner supply roller is charged to -450 vdc. The developing roller is charged to -300 vdc. Copyright 1997, Okidata, Division of OKI America, Inc. All rights reserved. See the OKIDATA Business Partner Exchange (BPX) for any updates to this material.
Page 67: Transfer
Page: 55 Service Guide OF1000 Chapter 2 Principles of Operation 2.5.07 Transfer The transfer roller is made of a conductive sponge material. The roller keeps the paper in constant contact with the image drum. Paper is placed over the image drum surface. A positive charge (opposite in polarity to the toner) is applied to the paper from the reverse side.
Page 68: Fusing
Page: 56 Service Guide OF1000 Chapter 2 Principles of Operation 2.5.08 Fusing After transfer, the toner image is fused to the paper by heat and pressure. The paper passes between the fusing roller and the pressure roller. The fusing roller has a teflon coating and contains a 400 watt halogen lamp.
Page 69: Cleaning
Page: 57 Service Guide OF1000 Chapter 2 Principles of Operation 2.5.09 Cleaning The image drum is cleaned at the end of transfer. The residual toner on the image drum is attracted to the cleaning roller, which has a + 400 vdc static charge.
Page 70: Printing
Page: 58 Service Guide OF1000 Chapter 2 Principles of Operation 2.5.10 Printing Refer to the Printing Process Diagram Printing is accomplished as follows. · Approximately - 1.3 Kvdc is supplied to the charge roller. This causes the drum to charge to approximately - 750 vdc.
Page 71: Sensors And Switches
Page: 59 Service Guide OF1000 Chapter 2 Principles of Operation 2.6 SENSORS AND SWITCHES 2.6.01 Paper Jam Detection Paper jam detection monitors the location of paper when the printer is powered ON and during printing. If any of the following jams are present, the printing process is interrupted and the message PAPER JAM will be displayed on the LCD.

Page 74: Paper Inlet Jam
Page: 62 Service Guide OF1000 Chapter 2 Principles of Operation Paper Inlet Jam This jam occurs when either of the following conditions occur. · When the printer is powered ON, paper is at inlet sensor 1. · After the hopping operation is attempted three times, the leading edge of the paper does NOT reach inlet sensor 1.
Page 75: Paper Feed Jam
Page: 63 Service Guide OF1000 Chapter 2 Principles of Operation Paper Feed Jam This jam occurs when either of the following conditions occur. · The paper does not pass over the paper sensor within a pre-determined period of time. · The leading part of the paper does not reach the outlet sensor within a pre-determined period of time after the paper has passed over the paper sensor.
Page 76: Toner Low Sensor
Page: 64 Service Guide OF1000 Chapter 2 Principles of Operation 2.6.02 Toner Low Sensor The toner well of the image drum cartridge contains a toner agitator. Whenever the image drum rotates, the toner agitator attempts to turn. A spring clip in the bottom of the toner well (along with the proper amount of toner) holds the agitator at the bottom of the well.
