The primary charge roller is a cylinder composed of a metal core and conductive rubber. Its main function is to bring a uniform charge to the drum core to absorb toner, and to eliminate the residual potential on the drum core. The primary charge roller is a new environmentally friendly charging method that reduces the generation of ozone, charges evenly, and is noise-free. It is widely used in laser printers and is also used in low-speed copiers. The voltage of the laser printer charging roller is -600V to -700V, and there are also positive charging ones. Charging electrode wires can charge at a higher level, generally between 6000V and 8000V. […]

1. Different implementation principles The biggest difference between chip-based toner cartridges and chip-less toner cartridges lies in the different implementation principles. The chip design of the toner cartridge adopts smart chip technology. The chip has a built-in program that automatically adjusts printer parameters through real-time monitoring and feedback of printer status, toner cartridge status and other information to achieve better printing results. The chipless toner cartridge does not have a built-in smart chip. It works directly between the printer controller and the toner cartridge driver. The traditional control circuit controls the work of the toner cartridge based on modes and signals, and cannot automatically adjust and optimize the printing effect. […]

1. Store detailed toner cartridge information (facilitates printing and identification of all toner cartridge models) 2. Display the print volume of the toner cartridge instead of controlling the print volume 3. Display area information (some printer manufacturers design different chip codes for different areas) 4. Failure to authorize the printer and toner cartridge passes a. Must respond accurately to printer requests b. Use the correct encryption method c. Respond within the specified time 5. Manage toner information according to printer requirements a. The printer determines the remaining amount of toner and writes the information to the chip b. The chip feeds back this information when the printer needs it 6. […]

1. There are sticky substances on the drum core, such as grease, etc. Solution: Wipe the drum core with a clean soft cloth 2. The powder is not filled in properly. Solution: Fill the powder carefully and don’t add too much at one time 3. Poor toner quality Solution: Choose good quality toner 4. There is a problem with the waste toner scraper (such as scratches, aging, etc.) Solution: Replace corresponding accessories 5. There is a problem with the powder bin scraper Solution: Replace corresponding accessories 6. The drum core is damaged Solution: Replace corresponding accessories Attached is a schematic diagram for replacing the toner cartridge OPC（Organic Photoconductor）:
