It's not the printer or the drum unit, for all I have to do is dump the toner from a new cartridge into an older toner cartridge that worked fine before it ran out of toner and instantly the print quality is fine.

Be forewarned that you should not buy toner until you need it or you risk finding the problem after the warranty date.

I will only use genuine Brother toner after a negative experience with generic toner

It leaks toner and does not print evenly, leaving faded out or unprinted areas on each page.

I learned my lesson last year to never buy so-called "compatible" toner cartridges, and I am not taking any chances on a remanufactured one either.

I have had a HUGE mess due to using a fairly well known replacement toner

For this genuine toner cartridge:Lowest price I could find + free shipping = 5 stars.

The excess toner caused some other problems in our machine that Brother, so far, refuses to take resposibility for.

BEWARE though, as the toner waste compartment in the drum assembly will fill up eventually and will spill into the printer if you do this

This new toner has been going strong for more than a month

However, this one totally failed, dumping toner into the drum and printer and probably causing the drum to fail (had to be replaced with 35% usage remaining)

In the past I have had poor experience with some low cost "compatible" toners, so I opted for the much higher cost Original Equipment Manufacturer-grade this time.

We called a business machine repair company who found that our machine was fine but the toner cartridge was defective and causing all the racket from leaking toner product

Received from Smart Ink & Toner

Now I have wasted money not just on two useless cartridges, but the drum has been messed up (toner powder got all over it) - and the inside of the printer is a mess...

It is definitely necessary to put tape over the optical sensor window on the cartridge (a tip I learned elsewhere on Amazon about Brother cartridges) to get full supply of toner out of the cartridge after it begins giving fake "toner low" messages.

I will buy a generic toner cartridge available on Amazon this time and will see how that works.

Spend a little more and buy a more respectable toner

The toner is working exactly how I need it to print

This toner is not good

This toner works great with the Brother All-In-One I have

We tested this toner against other more expensive cartridges and were totally satisfied with the performance of this Brother toner cartridge.

I bought 3 toners and 2 did NOT work properly, I even told a friend to use them too, and also had problems

By the way, that new toner worked as it was suppose to.

I ended up returning it to them and buying this Brother toner cartridge that works perfectly.

Last year I bought the same cartridge from Vision Supplies through this website, and it leaked toner into the machine from first installation until it died (still with toner within) about a year later, well under the advertised 7,000 sheets.

I have purchased over 20 of this toners through my local office store, this is a great toner but very costly, when I found out that Amazon retailers sold the exact same produc, with exact same quality, but at a much better price I couldn't believe it, so all my toner purchases are going to be done through amazon

but every time I made copies more toner was leaking

I believe that a genuine toner cartridge from the printer manufacturer is always better and safer for the printer than it's cheap substitute made by who knows which company
