1. First take out the toner cartridge
2. You can use a toner vacuum cleaner to clean the residual toner inside the printer. The price of a toner vacuum cleaner is about 300 US dollars, but the cleaning effect is far better than that of ordinary vacuum cleaners.
3. On the other hand, a soft cloth can be used to remove laser toner particles, and a soft cloth can be used to remove particles that are not removed by the toner vacuum cleaner.
4. Clean the crown wires, which are special wires used to transmit static electricity inside the printer. Static electricity is used to attract toner to the paper, but the precipitation of dust will affect the efficiency of static electricity use (especially for some old-fashioned laser printers). Users can use a cotton cloth to gently wipe off the dust, but please do not use alcohol or other solvents, which will affect the effect of the printer. Generally, in old-fashioned laser printers, the crown wire is exposed inside the printer. If they are not found, their location is indicated in the printer manual.
5. Next, you can re-insert the toner cartridge into the computer and start the printer to check whether the printer can still work normally after cleaning.
