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 clean.

In the seventh step (Drum cleaning block) the OPC drum is cleaned. On average, approximately 95% of the toner is trans- ferred to the paper during the print cycle. As the drum rotates during printing, the remaining 5% of the toner that is on the OPC drum is cleaned off the drum by the wiper blade. It is then guided into the waste chamber by the recovery blade, and stored in the waste chamber.

Step 8 is where the residual charge is eliminated. Here is where there is a major difference from previous HP car- tridges/printers. In all previous PCR based cartridges, the Primary Charge Roller places an AC voltage across the drum surface that erases any residual charges left on the drum sur- face.

These machines use the new second laser beam to eliminate the residual charges. This drum charge elimination is only turned on during the last rotation period of the drum.

With the higher speeds of these new machines, my guess is that using the PCR to erase the residual charges was not effi- cient at these speeds... This new laser process is.

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.
