CARTRIDGE THEORY
SUMMIT
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
SUMMIT
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 drum
SUMMIT
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

10. Remove the drum 12. Remove the two screws from the wiper blade
11. Remove the PCR
SUMMIT
16. Clean the PCR with your standard PCR cleaner
SUMMIT
19. Install the drum small gear side first onto the drum axle pin
24. Remove the MRS assembly
SUMMIT
Remove the two screws, spring and the holder
25. Remove the two doctor blade screws and the doctor blade. Note the clear plastic strip that covers the DB screws. Slide the screwdriver under the strip. Be careful not to damage the strip

SUMMIT
28. Note also the new heavy duty style magnetic roller contact. This when combined with the new larger diameter of the roller, allow the cartridge to run at the higher speeds that these machines are capable of
SUMMIT
30. Unlike the HP-4300 series where there are three separate mixing blades in the toner hopper. These cartridges just use one large mixing blade inside the toner hopper
SUMMIT
34. Remove the right side small bushing from the magnetic roller sleeve and install it onto the holder. Make sure the tab on the bushing aligns with the slot in the holder
SUMMIT
36. Install the MRS drive gear
SUMMIT
40. Install the right side end cap and five screws
