Toner cartriages of this model may not be very good.
So I am not purchasing this brand of cartriage this time.
Everything else that I have purchased from MonoPrice has been good though.
PROS: The cartriage fit in the printer ok, AND the original cost was lower than other vendors.
The print was OK for a while.
CONS: But it did not last, not even close to the page count shown in the data sheet. I purchased all 3 colors last time. I know that print coverage is a percentage of page print character area, it did not make it even close. I went to take them out, they spilled some pretty good size globs of toner out of them. The red one made little random shaped dots down the right side of the paper when it printed. These red dots and the toner low alarm are what alerted me to the toner cartriage problem. I looked at the page counter for the color prints.
I've had the HL-4070CDW for several years and it has been a great printer the main problem has been finding toner cartridges. The OEM cartridges never leaked (at least not enough to spread toner throughout the printer) and I never had to clean spilled toner - until now. The printer is a mess and the prints all have colored streaks.
PROS: Print quality is identical to the original Brother toner cartridges.
CONS: Toner started leaking from all the remanufactured cartridges after about 5-6 months.
