Why choose the genuine Brother TN-321Y toner
The TN-321Y is the standard version of the yellow cartridge in the TN-321 range. Genuine Brother toner powder, matched to the DR-321CL 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.
Standard or XL: TN-321Y or TN-326Y?
These references fit the same printers and differ only in the amount of toner: the TN-321Y (1,500 pages) and the TN-326Y (3,500 pages, about 28% less per page). The TN-321Y 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-321Y
The TN-321Y is compatible with 6 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
1,500 pages according to ISO/IEC 19798 (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-321Y and put the assembly back. The DR-321CL drum is a separate part rated for about 25,000 pages; the printer signals when it needs replacing. On these color models, the BU-320CL belt unit and the WT-320CL waste toner box are also separate parts (about 50,000 pages). Used Brother toners can be returned free of charge through the Brother recycling program.
Use and tips
The TN-321Y suits regular office use: the cartridge (1,500 pages) lasts about 5 months at 300 pages per month and about 2 months at 1,000 pages per month. Beyond that, the TN-326Y (3,500 pages) costs less per page.
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.
