Why choose the genuine Brother TN-3520 toner
The TN-3520 is the ultra high yield version of the black cartridge in the TN-3400 range. Genuine Brother toner powder, matched to the DR-3400 drum and the fuser of these printers: sharp text, even solids, no leaks and no "toner not recognized" message. Toner powder does not dry out, so a printer used intermittently keeps the same print quality.
Which capacity: TN-3430, TN-3480, TN-3512 or TN-3520?
These references fit the same printers and differ only in the amount of toner: the TN-3430 (3,000 pages), the TN-3480 (8,000 pages, about 36% less per page), the TN-3512 (12,000 pages, about 52% less per page) and the TN-3520 (20,000 pages, about 64% less per page). The TN-3430 suits occasional use; above 100 pages per month, a higher capacity costs less per page and is replaced less often.
Printers compatible with the TN-3520
The TN-3520 is compatible with 2 Brother models (manufacturer list):
Check the exact reference on the label at the back or underneath the printer; the suffixes (D, DW, DN, CDW) matter.
Page yield
20,000 pages according to ISO/IEC 19752 (5% coverage, letter-type text). Graphics-heavy or bold documents reduce the actual yield. The cost per page shown next to the price is calculated from the current price and this yield, excluding drum and paper.
Installation and maintenance
Tool-free replacement: open the front cover, pull out the drum + toner assembly, unclip the old toner, insert the TN-3520 and put the assembly back. The DR-3400 drum is a separate part rated for about 50,000 pages; the printer signals when it needs replacing. Used Brother toners can be returned free of charge through the Brother recycling program.
Use and tips
The TN-3520 suits intensive or shared use: the cartridge (20,000 pages) lasts over 5 years at 300 pages per month and about a year and a half at 1,000 pages per month.
Store the cartridge in its original packaging, flat, away from direct light and humidity (0 to 35 °C), and unpack it only when installing. At the "Toner low" alert, plan the order: the printer keeps printing until "Replace toner" (the "Continue" menu setting extends printing further). The driver's toner save mode suits drafts; genuine cartridges preserve the printer's Brother warranty.
