Page 46 Page: 36 Service Guide OF2200/2400/2600 Chapter 1 Principles of Operation 1.5.02 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. The registration gear turns, but the one-way bearing does not allow the registration roller to turn.
Page 47 1.5.05 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 48 1.5.06 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. As the toner supply roller rotates, toner is absorbed into the sponge type roller material. A charged particle will be attracted to a particle having a MORE POSITIVE charge than its own.
Page 49 The exposed portion of the image drum contains a more positive charge than the development roller (-100 vdc vs -300 vdc). Therefore, toner is attracted to the exposed areas of the image drum, making the electrostatic latent image visible. NOTE: The toner supply roller and the developing roller are supplied with the bias voltages required during the developing process.
Page 50 · A + 1 Kvdc charge is applied to the transfer roller. This causes the toner image to be transferred to the receive paper. · Heat and pressure cause the toner image to become fused to the receive paper. The 150 degree Centigrade fusing temperature is attained by turning a 400 watt halogen lamp ON.

Page: 37 Service Guide OF2200/2400/2600 Chapter 1 Principles of Operation 1.6 SENSORS AND SWITCHES 1.6.01 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 53: Paper Inlet Jam
Page: 38 Service Guide OF2200/2400/2600 Chapter 1 Principles of Operation Paper Inlet Jam This jam occurs when either of the following situations 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 54 Page: 39 Service Guide OF2200/2400/2600 Chapter 1 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 55 Page: 40 Service Guide OF2200/2400/2600 Chapter 1 Principles of Operation 1.6.02 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.
