In the first step, the Primary Charge roller (PCR) places a uniform negative DC Bias voltage on the OPC drum surface. The amount of the negative DC Bias placed on the drum is controlled by the printer’s intensity setting. This process is part of the latent Image formation block.

In the second step, (also part of the latent Image formation block), the laser beam is fired onto a rotating mirror (called the scanner). As the mirror rotates, the beam reflects into a set of focusing lens. The beam then strikes the OPC’s surface, which neutralizes the negative charge on the drum and leaves a latent electrostatic image on the drum. The laser unit actually fires 2 beams. The service manual talks about the second bean being used to erase residual charges, but not if it also helps to write the image.

The amount of the negative DC Bias placed on the drum is controlled by the printer’s intensity setting. This process is part of the latent Image formation blockSUMMIT The third step developing block is where the toner image is developed on the drum by the developing section, or supply cham- ber, which contains the toner particles. The toner is held to the magnetic roller sleeve by the stationary magnet inside the sleeve, and a DC bias voltage supplied by the high voltage power supply. This DC bias voltage is controlled by the printer’s density set- ting, and causes either more or less toner to be attracted to the drum. This in turn will either increase or decrease the print den- sity. Both the Primary Charge roller and magnetic roller DC Bias voltages are controlled by the printer’s density setting. The amount of toner on the magnetic roller sleeve is also controlled by the rubber Doctor blade, which uses pressure to keep the amount of toner on the magnetic roller sleeve constant. This blade also causes a static charge to build up on the toner, which helps keep the coating of toner even, and allows easy transfer to the OPC drumSUMMIT In the sixth step fusing block the image is then fused on to the paper by the fuser assembly, which is comprised of the upper fixing film assembly and the lower fuser roller. The paper passes between a heated upper fixing film assembly and a soft lower rubber roller. The upper heated element then melts the toner into the paper. The fixing film assembly consists of a Teflon sleeve with a ceramic heating element inside. These fusers are a bit different in that they have a Brush which has a DC Bias charge on it to help keep the film cleanSUMMIT REQUIRED TOOLSSUPPLIES NEEDED 5.
