Discontinued. Brother has retired the HL-L5100DN in favor of the HL-L5210DN/DW (TN920 toner), but TN820/TN850 toner and DR820 drums are still widely sold, including our compatible versions.

What HL-L5100DN owners ask

These come from owner reviews of the L5000 series at Best Buy and Staples and Brother's supply pages, answered in our words.

Does it have Wi-Fi?

No. The "DN" means duplex and network: Ethernet and USB only. The HL-L5200DW is the wireless version with the same toner.

Should I buy TN820 or TN850?

TN850; the standard cartridge yields less than half the pages for little saving.

Why are there spots on every page?

Check the drum for debris; if a mark repeats every few inches after cleaning, the DR820 is due.

How do I reset the toner message?

Reseat the cartridge firmly in the drum and close the cover; our chipped cartridges reset normally. If needed, Brother's manual reset is in the printer menu under Replace Toner.

Will it keep printing on "Replace Toner"?

Set Replace Toner to Continue in the menu to finish a job; order toner then.
