Refill your Samsung SCX-4100 series cartridge
Before use, familiarise yourself with the safety data on page 4 & 5.
Take maximum care when using a screwdriver as a lever. Use precautions such as gloves and eye-
protection to guard against injury due to accidental slippage.
Starter cartridge is different
When you buy a new machine, it arrives with a so-called “starter cartridge” that has a lot less toner
than the original cartridge you buy later. It also has a smaller toner compartment, so you can only
refill it with 30g of toner – about half of the amount that will fit into the bought Samsung cartridge.
How to spot the “fade-out point”
There’s no toner low signal from the machine. We were left to deduce that the cartridge was empty
as the image started to fade out vertically down the page, which normally happened from the right
side of the page. Taking the cartridge out and shaking it at the first fade out allows about another 60
pages to be printed before the fade out appears again.
Vertical fade-out that can be cured by shaking the cartridge, but then returns shortly afterwards, is
the tell-tale symptom of there being no toner left. If you want to be clinically precise, the weights of
the cartridges with no toner in are:
Starter cartridge empty weight 621g Original cartridge empty weight 676g

You might find that the stirrer blade confuses you. It’s a strip with
windows bonded to the same shaft that connects the two worm
gears. Pay no real attention to it. Focus on the worm gears being
just covered and the level being short of the foam gasket as
explained above. With the stirrer blade in play, the correct level
looks something like this.
7. CARE! A full bottle holds 3 times the toner you want to pour
in. Go little by little, stopping to even out the toner by shaking
the cartridge from side to side.
8. Hold finger firmly over end of spout, shake bottle for 10 seconds.
9. Slowly spread a layer of toner along length of compartment.

We’re aiming for a toner level that just covers those worm gears
so we can’t see any of their teeth. Here’s the right fill level:
you’ll see the toner level is just short of a foam gasket.
