CTG 40X5852AFT Compatible Charge Roller

[Music] the primary charge rollers pcr are used in many printers and copiers they are multi-layered rubber roller with conductive properties to be charged easily and evenly by the applied voltage you can find it above the drum it erases the charge of printed image from the drum surface then it applies an uniform negative DC bias voltage the laser writes the images on the drum discharging the areas that will receive the toner the toner is attracted to the discharged areas of the OPC only and is repelled by the charged regions of the drum background can arise if a defective PCR do not charge up the drum sufficiently to repel all toner some unwanted toner make it onto the white area and produces the so called background in a print the mechanism of the charging process is ionization of air in the gap between the PCR and the drum these charges will jump over to the drum of this ionization pr
