I have always loved Brother printers, but mine has become useless. The first time I had to replace the cartridge it started spreading ink all over the pages. Which caused it to begin running low after fewer than 100 copies. I am a teacher who can't afford this. The cost of the cartridge is already outrageous, and now I'm paying for unreadable copies and cleaning up ink all over my table.

Replaced the black toner cartridge for the first time since buying my brother printer brand new. About 3 months into ownership it was time to replace the black toner so I bought this high yield one (genuine Brother brand). Not only was I not emailed an invoice for business write off purposes, this unit leaves black smudges on every single paper and I have already tried cleaning out the drum/roller unit. It looks like it's a common thing. Try to find a better alternative. There's no reason why anyone should be experiencing this with a brand new printer and brand new toner cartridge that is the same brand as the printer.

I bought this original toner because in the past I have had trouble with "compatible" toners. This was $30.00 more but I unwrapped it and installed it with no problems. This cartridge has a chip and an internet search said some compatible toners had chip trouble.

I installed a black high density cartridge after the original one ran out. I was not disappointed in the number of copies printed from the original cartridges, nor the quality of prints. My colored cartridges have now run low, and I'll be replacing them with high yield ones. If these cartridges do not perform, I will change my review, but I am very satisfied.

Purchased the Brother MFC-L3710CW for a small office and it has been nothing but horrendous. Within months the ink supplies were depleting rapidly and the printing is horrific. Our invoices are barely visible to customers and there is a constant issue with this machine. Definitely do not recommend for business.

My Brother laser printer worked great until the first time that I had to replace the toner. I bought this Brother-brand toner and it was a disaster. It left smears on the papers from day one and only got worse over time. This was a huge waste of money.

I finally replaced a 15+ year old Brother B&W laser printer with a scanner/color laser unit. After I used up the black toner cartridge shipped with the printer, I replaced it with this high yield cartridge. With a 3000-page rating, I assumed it would last me for years, but after 8 months (with 90+% of its capacity remaining) it began printing with smudging and vertical bands. After doing all the cleaning and troubleshooting, the problem persisted. Replacing the cartridge fixed the problem immediately. The 90-day warranty Brother offers is a joke. I'm left with a nearly full but useless cartridge.

First, they will brick your printer if you use any toner except their brand, then they delete reviews that tell the truth about this. Brother- Do you read the reviews for this toner? Please tell us why should we trust your brand of toner over any other?

After printing only 5 sheets with a brand new L:3290CDW, the back toner started to smudge across the entire sheet. The brand new printer and the genuine Brother supplies. It looks like a total waste of money. Brother should fix that problem free of charge.

I purchased two of these printers for my office and I’ve had to replace these toner cartridges after a few hundred prints at most. I think it’s too convenient that brother claims up to* 2,300 prints when in regular use we’re averaging 20% of what’s claimed. I bought these printers hoping to save money in the long term and may now have to replace them.
