Dr. Blade

The Doctor Blade has mainly two functions:- To regulate the amount of toner available on the magnetic developer roller, and help tribioelectrically charge the toner so that it properly develops the image on the OPC drum. Their surface finish, hardness and dimentional accuracy are all critical to proper functioning

Primary Charge Roller (PCR)

The main function of the PCR is to charge the OPC by breaking down the air gap formed in the nip areas of both sides of the PCR.The PCR rolls on the OPC surface to transfer the charge to the OPC surface. PCR applies a uniform negative charge (-600V to -720V DC) on the surface of the drum. If this charge is not uniform and even, toner is attracted to the desired areas of the drum. A poorly charged drum can streak or background shade.

Develloper Roller

The Develloper roller is the crucial link in the imaging system since it brings toner to the drum so an image can be transferred to the page. If the developer roller is not replaced when worn or damaged cartridges may show light print, backgrounding, or heavy banding.
