The cartridge is quite Identical to the original cartridge Brother and fits just as perfectly in our HL-2030th Just wanted to recognize the printer toner this until after I got the note from the provider, bringing the white lever that is located on the left in a semicircle, with a pair of pliers to "Twelve-clock" to. It has even cracked briefly - but everything was healing - and then accepted the printer and this toner cartridge. After a few test pages (three times briefly on the printer button) gave the printer but a perfect print image. Of the capacity, I can not tell now, of course.
