Many printer toner cartridges do not actually use up the toner in the laser printer selenium when they are replaced. Some toner is often left in the waste toner box or toner box. If it is not cleaned, we will add toner. With the original toner, it may form a blocky solid due to incompatibility. Therefore, we must clean the original toner cartridge before adding the toner. When cleaning, first pour out the toner in the waste toner box and the toner cartridge, and then use a brush to gently remove the toner remaining on the edge of the toner cartridge.

We can use a leather tiger or a hair dryer to clean the waste toner where the brush can't clean. After cleaning the toner in the toner cartridge, we also need to use a brush to clean the toner around the toner cartridge. After cleaning the waste toner in the toner cartridge and the waste toner box, we will also clean up the waste toner on the charging roller and magnetic roller. Let’s take the cleaning of the charging roller as an example to introduce the cleaning method. When cleaning the charging roller, first find the fixing screws of the charging roller (usually on both sides of the charging roller), and use a screwdriver to unscrew the screws. Carefully remove the charging roller from the toner cartridge. Generally, both ends of the charging roller are equipped with plastic gears. Before wiping, we must remove the gears at both ends of the charging roller.
