Toner Cartridges for the Samsung SCX-4021S

When it's time to replace your Samsung SCX-4021S toner then look no further than our range of cartridges and maintenance products on this page. Not only will you find our prices incredibly low but everything comes with free next day delivery included in the price you see.
The Samsung SCX-4021S accepts a black toner cartridge with the reference MLT-D101S and this will allow you to print somewhere in the region of 1,500 pages.
While our prices are cheap for the original Samsung toner, the most popular option for the SCX-4021S is our own brand compatible toner. Not only do you get a much lower price but we guarantee the quality with our amazing 3-year warranty. This covers the toner cartridge and your printer.

You can trust TonerGiant.

TonerGiant has been selling Samsung printer consumables since 2006 and in this time we have earned a reputation for outstanding service. In fact we've won several customer service awards and also have great feedback on independent review websites, including Feefo.
So when you're ready to order toner for your Samsung SCX-4021S, choose TonerGiant and we'll deliver much more than printer cartridges.

Order before 5:30 pm on any working day and so long as the products are in-stock, your order will be delivered on the next-working-day.
How long do the toner and drum last on the SCX-4021S?
The toner cartridge (MLT-D101S) lasts around 1,500 pages at 5% coverage. The drum (inside the imaging unit) typically lasts around 9,000–10,000 pages before print quality declines.
Why is my Samsung SCX-4021S printing very faint, light, or “washed-out”?
This usually happens when the toner, drum, or print settings need adjustment. Remove the toner cartridge and gently shake it side-to-side to redistribute toner evenly. Make sure Toner Save Mode is turned off and print density is set to “Dark.” Wipe away any loose toner or dust inside the printer using a dry, lint-free cloth. If prints are still pale, replace the MLT-D101S toner cartridge from a reputable supplier such as TonerGiant.co.uk. Low or old toner is the most common cause.
