How does the Samsung ML-2010D3 toner drum work?
It is important to know that the Samsung ML-2010D3 compatible black toner cartridge comes with its OPC drum unit included, rollers, toner, and seal. As we stated in the title we are going to focus on the job of the drum unit today.
Just as much as the toner is essential to see the image on the paper, the drum has the duty to set it there. It might sound a bit complicated but it is highly enlightening (especially because it actually uses laser beams, get it? Ok techie joke, its Monday madness). The following is the process step by step:
1) First the beam of the Samsun ML-1610 printer’s laser strikes the photoreceptive drum, etching a reverse image of the document or image to be printed. The light causes the area on the drum it strikes to take on a negative charge.
2) Then the drum continues to roll and as it approaches the toner hopper, the positively-charged toner particles stick to the image drawn by the laser and stays there until it contacts the paper.
3) After the toner is drawn from the drum because the paper, having passed under a "corona wire" has a stronger negative charge. The paper is prevented from sticking to the drum because soon after the paper contacts the drum, it passes over another corona wire which gives it a positive charge.
4) The next step is that the drum rotates under a "discharge lamp" which is a very bright light. This removes the image drawn on the drum by the laser by giving that area of the drum a total negative charge.
5) Finally the drum then rotates under a corona wire of its own where it receives a total positive charge and is ready to be drawn upon by the laser once again.
So taking into consideration the importance of the drum while we are in the printing process then you understand why your paper says to your printer each time you send the print command: “Beam me up Scotty”
