Samsung ProXpress SL-M3820, SL-M4020 - Replacing the Toner Cartridge

This document explains how to replace the toner cartridge. When a toner cartridge has reached the end of life, the machine will stop printing. A toner cartridge has almost reached its estimated cartridge life when:
  • The status LED and the toner-related message on the display indicate when the toner cartridge should be replaced.
  • The computer’s Samsung Printing Status Program window appears on the computer telling you when the cartridge is empty.
  note:
  • Shake the toner cartridge thoroughly, as it will increase the initial print quality.
  • Illustrations may differ from your printer depending on its options or models. Check your printer type.
  caution:
  • To prevent damage to the toner cartridge, do not expose it to light for more than a few minutes. Cover it with a piece of paper, if necessary.
  • Do not touch the green area of the toner cartridge. Use the handle on the cartridge to avoid touching this area.
  • Do not use sharp objects such as a knife or scissors to open the toner cartridge package. They might scratch the drum of the cartridge.
  • If toner gets on your clothing, wipe it off with a dry cloth and wash clothing in cold water. Hot water sets toner into fabric.
