What Ink Does the Brother MFC-J6930DW Use?
Last Updated:Last updated: September 27, 2026. Reviewed by William Elward, founder of Castle Ink.
Correction: an earlier version of this article listed the MFC-J5930DW as an LC3017/LC3019 printer. It uses LC3029.
Quick answer: what ink does the Brother MFC-J6930DW use?
The Brother MFC-J6930DW uses 4 Brother LC3017/LC3019 cartridges: black, cyan, magenta, and yellow. Standard LC3017 and higher-yield LC3019 cartridges fit the same slots. LC3019 super-high-yield cartridges are rated for about 3,000 black and 1,500 color pages, several times the LC3017, so they're the better value for regular office printing. Each color is a separate cartridge, so you only replace the one that runs out.

| Brother LC3019 black (super high yield) | LC3019BK | ~3,000 pages |

Common questions about Brother MFC-J6930DW ink
Should I buy LC3017 or LC3019 for the MFC-J6930DW?
LC3019 for most people. LC3019 super-high-yield cartridges are rated for about 3,000 black and 1,500 color pages, several times the LC3017, so they're the better value for regular office printing. See Is XL ink actually worth it? Standard vs. XL with real numbers.
Can I mix standard and high-yield cartridges?
Yes. Each cartridge is read separately, so any mix of LC3017 and LC3019 works.
What other printers use Brother LC3017 ink?
LC3017/LC3019 also fits the MFC-J5330DW, MFC-J5335DW, MFC-J5730DW, MFC-J6530DW, and MFC-J6730DW. If you own more than one, a single stock of cartridges covers them all.
Will other Brother cartridges fit the MFC-J6930DW?
No. Brother LC3029 (MFC-J5830DW, MFC-J5930DW, MFC-J6535DW, MFC-J6935DW) and LC3037/LC3039 (MFC-J5945DW, MFC-J6945DW) look similar but won't fit. Always match the number on your current cartridge.
Are compatible LC3017 cartridges safe for the MFC-J6930DW?
Yes. Quality compatible and remanufactured cartridges print like OEM, and using them doesn't void your warranty under U.S. law. If the printer shows “Cannot Detect” with a new cartridge, reseat it and check that the orange cap is removed.

How do I replace the ink in the MFC-J6930DW?
Open the ink cartridge cover on the front of the printer. Push the lock-release lever for the empty color and pull the cartridge out. Unpack the new cartridge, remove the orange protective cap, and push it in until it locks. Close the cover; the printer resets that color's ink counter automatically.
Why does the MFC-J6930DW say “Cannot Detect” or “Cannot Print”?
Remove and reseat the cartridge until it locks, make sure the orange protective cap is off, and wipe the cartridge's contacts with a dry lint-free cloth. Turn the printer off for a minute. If one color is empty, most Brother inkjets stop printing until it's replaced. More fixes: Printer says ink cartridge not recognized: how to fix it.
Why are prints from my MFC-J6930DW faded or streaky?
From the control panel, run Ink (or Maintenance) > Improve Print Quality > Check Print Quality, then clean the colors that show gaps. If lines look jagged or doubled instead, run the alignment from the same menu; see our print head alignment guide. More: Why is my printer printing streaks?.
Why did the first set of cartridges run out so fast?
New printers use part of the first set to fill the ink system. It's a one-time cost. See why the first cartridges run out fast.
Can the MFC-J6930DW print 11x17?
Yes. It's a business all-in-one that prints up to 11 x 17 (ledger) size and can scan and copy at that size too.
LC3017 or LC3019: which should I buy?
LC3019 for most offices. It costs more per cartridge but is rated for about 3,000 black and 1,500 color pages versus about 550 for LC3017, so the cost per page is much lower.
