You can ONLY use DELL replacement toner.

Printer works great but a huge negative is it will only accept DELL replacement toner. If you use an off brand "compatible" toner it will not reset after toner replacement. This is not clearly stated and very deceptive.

I purchased this toner as it stated that it was for the Okidata B431D printer. It worked for a while and then after a month the print quality deteriorated rapidly. I started getting streaks in my printing. I called Okidata support and they informed my that the toner in this replacement cartridge was not designed for this printer and it has ruined my drum. I have to replace the drum. Apparently because I purchased a Non-OEM toner, the warranty is void. I have to buy a new drum which is ~$200.00.

Very annoying printer overall.

The set up for WIFI was pretty difficult.

The quality of color prints is good.  The quality of black and white is overall very good which is why I gave it 2 instead of one star.

They really try to nickle and dime you.  If any of the 4 expensive cartridges are out you cannot use the printer.  Even if you have plenty of black toner and you just want to print black and white.  If the Dell program senses low ink on any cartridge it will not allow you to print in any color...

Original printer toner lasted about 130 pages. Thought it was an issue with new printer sample toner. Bought this cartridge and replaced yellow only from the pack and printed about another 130 pages and strangely this new "GREENBOX" yellow cartridge ran out. Not sure if it is the printer issue or the ink, I am not printing any pictures or just some regular text mostly B&W. The original B&W cartridge has about 50% and the rest of the colors has about 70%, strangely running out on yellow only. When I call dell they say unless you use dell cartridge we cannot say there is an issue with the printer. in 5 months printer about 260 pages.

Don't buy this.  Buy the original Dell toner instead.  I just installed the toner cartridge today.  It leaks the toner all over my printed sheets.  I have cleaned the roller to no avail.  In the past I've had this problem with re-filled cartridges, but this is the first time with a new cartridge.

I bought this replacement for my Dell 1710.  It installed and just printed fine, initially. Then, the printer lights came on and the printer stopped printing - indicating a toner problem. I contacted the company and they said it needed to unplug the printer and wait a few minutes, then plug it in again.  I did that and it worked for a while, then stopped working again, same thing: toner problem.

I have to do this restart routine every 5-20 pages I print. Major hassle.
Not worth the savings.

This review will be in the format of comparing this product to its Samsung OEM (original equipment manufacturer) equivalent.
(Samsung's printer/toner compatibility chart can be found here: [...])

PRINTER PURCHASED FOR:
Samsung ML-2010 Mono Laser Printer

OEM TONER CARTRIDGE EQUIVALENT:
Samsung ML-2010D3 Black Toner

REASON FOR PURCHASE:
I originally purchased this product because my printer was acting up. Occasionally, when I starteded a print, the printer would take in half of a page, then jam and stop, and I would have to restart the printer and try again. Therefore, I figured changing the toner cartridge may solve the issue.

PRICE (AS OF 11/21/2016):
This product is only $35.76 and comes with TWO toner cartridges. Samsung lists JUST ONE OEM toner cartridge for $114.99 on their website.

AVAILABILITY:
This product can be purchased with one click directly directly from Amazon. Samsung states that their OEM toner cartridge can only be purchased from several local stores listed on their website, not online. For many of these stores, the OEM toner cartridge is out of stock. Having to contact several local stores about the availability of Samsung's OEM toner cartridge is extremely inconvenient and time-consuming.

YIELD:
This product has a 3,000 page yield - the same as Samsung's version of this toner cartridge. I am unable to compare my personal yield between this product and Samsung's OEM toner cartridge because... 1) I only used this product for about two weeks prior to purchasing a new printer... and 2) I was not keeping track of the yield of the Samsung OEM toner cartridge that was originally in my printer.

QUALITY:
I did not notice any quality difference between this product and Samsung's OEM toner cartridge. Both toner cartridges produces the same color richness with no smearing.

WARRANTY:
This product has at least a 12 month warranty! I was unable to readily find warranty information specifically for Samsung's OEM toner cartridge on either Samsung's or the local stores' websites.

THE ONLY DOWNSIDE:
I replaced the ML-2010 printer with a M2825DW, which takes a MLT-D116L toner cartridge. I don't believe that this product is compatible with my new printer, which is extremely unfortunate.

SUMMARY:
I can confidently say that this product is the best choice out of all other compatible toner cartridges AND Samsung's OEM toner cartridge. Compared to many other compatible toner cartridges, this product is definitely the cheapest. Compared to Samsung's OEM toner cartridge, this product...
- IS ALMOST 6.5 TIMES CHEAPER!!!
- has the exact same specs
- doesn't fall short on quality
- has a much faster and more convenient purchasing process

Unfortunately, replacing the toner cartridge did not solve the issue I was having with my previous printer, but nonetheless this product was excellent! It was definitely compatible with my printer and I had no issues with the product itself whatsoever. In the future, once my new printer requires a replacement toner cartridge, I will surely purchase an INK E-SALE one.

I installed the black toner cartridge thinking it was compatible with the dell 3100cn. It installed ok, but made a mess in the printer and ran out of toner ink within a week. It also came up with a error to reseat the toner cartridge several times. It would work for a little while before the error kelp coming back. I had to order another toner cartridge from dell.

Terrible replacement toner that caused my printer to jam all the time

As the title says, this is not a good replacement toner. I used other after the market toners before. This one is by far the worst. It caused my printer to jam almost all the time in the first week of use and I now have to order another toner.

Not good. (Review is for all colors + black). They work, but print quality is horrible. Very washed out and uneven prints. Why bother with these?  Dell branded work great of course, as well as another brand found here (3 letters beginning with the 2nd vowel). Note: for either 3rd party brand, I do not enable the (non Dell toner) printer option.

No problems with this re-manufactured toner cartridge. Works well. Just like the Dell except costs a lot less.

The page does a poor job of describing what this item is and does.

I just bought a Samsung CLP-300 printer, and read in the manual about the Samsung Waste Toner Collector (CLP-W300A) and what it does.

One of these (the collector) comes with a new CLP-300 series printer.  This is a bottle that fills as you print, with toner that is taken from the toner cartridge cylinders, but not used during the printing process.  Samsung seems to have had a good idea doing it this way rather than having it accumulate in some inaccessible space within the unit.

The Toner Collector also has what appears to be an optical port on the side (most likely to enable the printer to tell when it is full).

The documentation that comes with the printer specifies the Toner Collector needs to be replaced when full, which (it seems) they expect after printing between 1250 and 5000 pages (at 5% saturation for color and B/W print, respectively).  Failure to replace A FULL Waste Toner Collector results in stoppage of printing.

I don't see any reason not to simply dump the toner and clean out the supplied collector when it gets full, except that that could turn out to be a messy job, and it may be simpler to plunk down the 10-15 bucks to just buy a new one.

In summary:  this Waste Toner Collector is an internal part of the Samsung CLP-300 series printer, found just inside the front access panel, and it is easily removed and replaced.

We are not happy with it the toner is expensive and it stopped working at 1 year not worth the money and not the quality we expect from Dell.

Plan on buying a new toner about every week.  It will only print about 1-2 reams before it has to be replaced.  And they are very expensive toner replacements.

This didn't work for my printer and it leaked yellow toner all over.  It also was NOT manufactured by Dell.  I feel this is misleading.

The wireless setup didn't work. Only way to fix it was to turn it off, and restart for it to recognize the wifi connection. tried new modem with it and same thing(my notebooks all pick up my wifi modem just fine) . Also The starter toner was almost empty when i received it. I only tried the black and white prints yet the starter ink said it's was almost out on color toners and blk toners! It also doesn't allow you to override low toner message. HUGE HASSLE to return this HUGE, heavy printer only to have to find a new printer now. I will have to think twice before buying dell.

The printer does everything it says it can do and the wireless was super easy to set up. Unfortunately the toner runs out so much faster than the pages quoted on the box and at $75 and over for each high yield cartridge, this is unacceptable. Also they have features in place that do not permit you to refill their cartridges, and do not allow you to use off brand toner. They are selling $5 worth of toner for over $75, and it turns out its not even the full amount, and now your impact on the environment is about as bad as the impact on your wallet. I assume they are getting away with it because the printer will re-order when you need more (so you always have it on hand). I have always loved Brother printers because in the past they worked well, inexpensively, and forever, but it turns out times have changed. They should rename their company to Big Brother.
