CanonGenuine 128 Black Toner Cartridge Compatible with MF4450, MF4770n, MF4570 Series, MF4800 Series, D530, D550, L100, L190

This cartridge was indeed a genuine Canon cartridge. Some other reviewers have stated they got an off-brand cartridge, but mine was definitely the real deal, complete with a Canon-branded box that can also be used to return your old cartridge for recycling. If you somehow receive an off-brand, you should return it to amazon and inform them of the error.The cartridge indeed lasted as long as they claim. The ink is good quality, nice and black, and consistent til the very end of the cartridge.This cartridge contains the toner and drum all in one piece, which is why it seems more expensive. In the long run, you're actually saving money and hassle by not needing to replace the drum separately. It helps you easily keep your printer in great condition with minimal maintenance.The packaging of these is great. They are very well-protected while taking up a minimal amount of space, which makes the box as small as possible. Smaller boxes means less storage space taken up by your spare cartridge. As stated above, the box and its packing materials can then be used to send the old cartridge back for recycling. They include a pre-paid UPS mailing label, and then you can easily drop it off to be sent back.

Our 20 year old Canon desktop copier still works like new, maybe because we only feed it these Canon OEM toner cartridges. No issues encountered; glad they are still available from Canon.

Working in a busy medical office; our fax machine is always running. Having to run to Staples or Office Max once every month or too was a pain and not very cost effective. Ordering from this seller allows us to order in bulk for less than the big box store retail price without compromising the integrity of the prints that we get and remain confident in the quality of the product. Will always have this item on my buy again list from this same seller.

This cartridge has always been very dependable to use! This cartridge is only B&W, so no color is needed.The print is very easy to read.

It was exactly what I ordered.

The "starter" cartridge on my Canon MF4770 printer ran out of ink after a few hundred pages, so it was time to replace it. I decided on a genuine Canon cartridge.=== The Good Stuff ===* It works. It came well packaged, installed easily, and works great. Output is crisp and sharp, although I almost exclusively print text on this printer, so no great challenge. I managed to finish the job without making a mess or getting my hands all black, one of my measures for success.=== The Not-So-Good Stuff ===* I never like the price of these things. The printer was only $130, so it is obvious that Canon gives away the printer to make money on the ink-so what can you do. I don't do all that much printing, so while I get upset when buying the cartridge, it really isn't all that big a deal.I didn't try any sort of refill/3rd party cartridges with this printer. Based on previous experience, I have just found them to be more trouble than they are worth. Your mileage may vary.=== Summary ===I hate the price of these things, but hate the problems I have had with 3rd party solutions even more. So I just hold my nose, pay the price, and install the new cartridge. Then I forget about it until it is time to replace it again. Not ideal, but such is life.

My ink cartridge arrived earlier than expected. There was no damage to the packing and the ink cartridge is exactly what I needed to keep printing. I will definitely will use Office Depot on Amazon again!!!

I bought this in January but just put it in the first week of April. It is now out of ink. They usually last me 8 months. This is too late to get a refund and money I didn’t want to waste! I will not buy this again.
