(2) Remove the setscrew (BT3x8, 1 piece) to remove the plate.
(3) Remove the waste toner feeder PU from the frame.
NOTE:
• One end of waste toner feeder PU is supported by the hole inside the frame.
• In this instance, as the waste toner may leak from the toner feeder part in the pipe, prepare
the waste toner tray to prevent the waste toner from falling on the floor.
• Clean the inside of the machine, if any stain, with the vacuum cleaner that is for the toner
only.
• It would be better to apply a grounding wire to the vacuum cleaner to prevent static
charge.
• Vacuum the toner remained in the waste toner feeder pipe.
