How to Refill Samsung SCX4100 Laser Printer Cartridge

A new laser printer cartridge can cost you $40 - $100, depending on the brand and condition of the cartridge. Although the cost of printing 1 page is only 2 cents (assuming each cartridge can give you 3000 pages in normal quality as the manufracturer claims), you can save even more on printing by refilling your cartridge.

Here is an instruction of refilling my Samsung SCX 4100 laser printer. Most laser printer refill processes are similar, unless your laser printer is the one that has a chip that needed to be reset.

Things You'll Need

• Refill Toner Kit (toner and glove)
• Screw Driver

Instructions

1. Buy the refill powder (search "toner refill" online). Yeah, for laser printer, what you need is ink powder, not liquid. The price of the toner refill varies, depending on the weight of the refill. The refill package usually comes with a bottle of ink powder, a pair of gloves, and an instruction.

2. 

   Get your old cartridge out of the printer, and remove 5 screws. Screws locations are shown in the picture below

3. Open the cartridge cover and pour the powder out. Roughly estimate the amount of the old power, as you will need to determine how much new power is needed to pour back into the cartridge.

4. There is a refill hole (blocked by a cap) located at the rear of the cartridge. Remove the cap from inside of the cartridge and reattach the cartridge cover to its original position. Put the 5 screws back firmly.

   Pour the refill powder in cartridge via the hole. Remember just feed the cartridge 70 - 80% full. Last step -- put the cap back.

Tips & Warnings

• First, don't touch the drum (the green part) on your cartridge.

• Second, don't fully refill the cartridge, only make it 70% or 80% full.

• It is highly recommended to do the process in the places like garage or balcony, because the ink powder will leak out no matter how carefully you process the proccedure.
