No. Toner refilling made according to the instructions will never harm your printer. Developed countries support the toner cartridge refill process to encourage recycling to protect the environment. Sometimes, we encounter questions from consumers whether toner will damage my printer. These questions are partly due to the original printer services’ desire to direct consumers to purchase original toner / additives. Each laser printer should be maintained at certain intervals, and after a certain number of prints, some parts that have expired should be replaced. This is the case even if the original toner is used, even if the toner is refilled.
