Screw off the cap of the toner bottle of corresponding color and tear off the sealing film--- make the toner cartridge stand upright with the perforated end turning adown (and lean against the stent)and insert the toner-guide tube of corresponding color into the toner extraction hole provided on the valid toner cabinet---open the corresponding toner control valve (the toner control valve can be opened in advance)---open the cover the toner refilling container---pull the machine switch upward and open the corresponding accelerator switch and insert the toner bottle jack into the toner refilling container so as to let the toner flow into the toner refilling container and toner cabinet (if the toner is obstructed, it is appropriate to pinch the toner bottle with hand to force the air inside the bottle to rush downward, so as to impel the toner to flow down or insert the stainless steel pin into the toner refilling container to stir the toner)---pull the toner refilling tube out when there is no waste toner flowing out from the toner cartridge, close the switch of accelerator and pull the machine switch in the middle position,pull out the refilling tube and wipe up with soft cloth and insert it into its original place---seal off the waste toner extracting orifice with adhesive tape (two layers of adhesive tape should be provided, the maximum bore diameter of the first layer is around 20 mm, and the second layer should extend from the edge of the first layer by 15mm)

With regard to color toner cartridge, it is applicable to repeat above procedures.
