Will Not Fit

• DR920 vs. DR925: the Brother Workhorse models (HL-L5215DW, HL-L6415DW, HL-L6415DWT, HL-EX415DW, MFC-L5715DW, MFC-L6915DW, MFC-EX915DW) use the DR925 drum, not the DR920, even though they take TN920-series toner.
• DR920 vs. DR820: the older HL-L5200DW / HL-L6200DW / MFC-L5700DW generation uses the DR820 drum and TN850/TN880 toner. They are not interchangeable with DR920.
• Drum vs. toner: this is the drum only. It does not include toner and does not replace a toner cartridge.

Installation & Printer Messages

Installing: remove the new drum from its bag and take off the orange protective cover. Open the front cover, lift out the old drum and toner assembly, push down the green lock lever and move your toner cartridge into the new drum until it clicks. Slide the green tab back and forth a few times to clean the corona wire, then slide the assembly back into the printer.

Reset the drum counter: after installing a new drum, reset the counter from the printer menu (look for Machine Info or Parts Life, then Reset Drum). Installing new toner does not clear a "Replace Drum" message. If a non-genuine supply notice appears, choose OK or Continue.

Frequently Asked Questions

How long does the Brother DR920 last?

Brother rates the DR920 at about 45,000 pages when printing one page per job, and up to about 75,000 pages at three pages per job. The drum usually outlasts several toner cartridges.

Is the DR920 the same as the DR925?

No. The Workhorse models use the DR925 drum. They take TN920-series toner, but the drums are not interchangeable.

Do I need a new drum when I replace the toner?

No. The toner and drum are separate. Replace the drum only when the printer shows "Replace Drum" or prints show repeating marks that a new toner doesn't fix.

How do I reset the drum counter after replacing the DR920?

Open the printer menu, go to Machine Info (or Parts Life), choose Reset Drum and confirm. Do this only after installing a new drum.

Will this void my printer warranty?

No. Under the U.S. Magnuson-Moss Warranty Act, a manufacturer can't void your printer warranty just because you used a third-party supply. If a non-original part directly caused damage, that specific repair might not be covered.
