Samsung ML-4550, ML-4551 Laser Printers - Replacing the Toner Cartridge

This document explains how to replace the toner cartridge in your printer. When a toner cartridge has reached the end of life, the printer will stop printing.
  note:
  • Before opening the top cover, close the output support first.
  • Do not touch the green underside of the toner cartridge. Use the handle on the cartridge to avoid touching this area.
  • 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.
  • If toner gets on clothing, wipe it off with a dry cloth and wash it in cold water. Hot water sets toner into fabric.

  4. Locate the sealing tape at the end of the cartridge and carefully pull the tape out of the cartridge. Discard the tape after you have removed it.
      caution:
    Be sure to keep the tape straight when pulling it out of the cartridge. Do not cut the tape. If the tape is not removed correctly, the cartridge cannot be used.
      note:
    The tape should be longer than 60 cm when removed correctly.

    The tabs on the sides of the cartridge and the corresponding grooves inside the printer will guide the cartridge into the correct position.
