Samsung ProXpress SL-M3820, SL-M4020 - Replacing the Imaging Unit

  caution:
  • Do not use sharp objects such as a knife or scissors to open the imaging unit package. They might scratch the surface of the imaging unit.
  • Do not touch the green area of the imaging unit. Use the handle on the imaging unit to avoid touching this area.
  • To prevent damage, do not expose the imaging unit to light for more than a few minutes. Cover it with a piece of paper to protect it if necessary.
