Brother HL-L2370DW Toner: Replacement, Reset & Compatible Cartridges

The Brother HL-L2370DW uses one black toner cartridge ,and a separate drum unit , which is kind of two things you swap out on different schedules. In this guide I cover the whole thing ,like what toner to pick, how to replace it and perform the reset , how to reset the drum too, and what the “XL” bit means when it shows up in the model name.

What Toner Does the Brother HL-L2370DW Use?

The Brother HL-L2370DW works with three toner cartridge options in the TN-700 line. These three cartridges are built the same way ,and they slide into the printer the same exact way. The only real difference is the yield, basically how many pages you can print before it runs out.

TN-760 is the sort of cartridge that most people end up using. Roughly 2.5× the page yield of the TN-730 for a modest price lift, so the per-page expense drops a lot. Brother also sells the DR-730 drum unit, that’s a separate piece rated for about 12,000 pages and it gets changed far less often than the toner itself.

Starter cartridge note: New HL-L2370DW printers usually include an in-box starter toner, sometimes it’s labeled TN-730. That one gives fewer pages than a normal retail cartridge , commonly something like 700–900 pages. When you do your first replacement, it will probably feel like you got a big jump in endurance.

Does the HL-L2370DW Use Color Toner?

No – the Brother HL-L2370DW, it doesn’t use color toner. It is a monochrome printer, black and white only, laser type, so it runs on just one black toner cartridge, that is it. There isn’t any cyan or magenta, or yellow cartridge , so it can’t spit out color output in any way.

If you searched for “brother hl l2370dw color toner” and somehow ended up here, ok, here’s the quick clarification, no color toner exists for this device, because the machine itself is black-and-white only. The imaging system uses a single drum and a single toner cartridge, both are black.

If you actually need color printing, you’d have to pick another model. Like the Brother HL-L3220CW or HL-L3300CDW, those are color laser printers in Brother’s lineup.

Compatible toner for the HL-L2370DW:

• TN-730 (black, standard-yield)
• TN-760 (black, high-yield)
• No color cartridges exist or are compatible

How to Replace the Toner Cartridge (Step-by-Step)

Toner replacement takes about two minutes. You do not need tools, and you do not need to touch the drum unit unless you are replacing it at the same time.

You’ll know it’s time when

• The printer shows “Toner Low” or “Replace Toner” on the LCD
• The print output starts looking faded , streaky, or even kind of uneven
• You get a “Toner Life End” warning shows up

Steps:

1. To start, open the front cover by pressing the release button on the front of the printer then pulling the cover down, fully… like all the way.
2. Take out the toner and drum assembly by pulling it straight out toward yourself. The toner cartridge and the drum unit come out together as one piece.
3. Now separate the toner from the drum. Hold the drum unit still with one hand, press the green lock lever on the left side of the toner cartridge, and pull the toner cartridge out of the drum unit. Put the drum unit aside on a flat surface, just don’t touch the green roller on the drum.
4. Unbox the new toner cartridge. Remove everything like packaging and protective tape. Give it a gentle shake, side to side about 5–6 times so the toner powder spreads evenly in there.
5. Slide the new cartridge into the drum unit. Feed the toner into the drum until you feel it click into place. You should notice a clear snap sound when it’s seated right.
6. Reinstall the drum-and-toner assembly. Slide it back into the printer along the guides until it stops and sits in firmly.
7. Close the front cover. The printer will do a short initialization cycle and then you should be ready to print.

Try not to touch the drum’s green roller at any point during this whole routine. Grease, fingerprints on the drum surface can cause permanent print issues. If you accidentally touch it, the drum might have to be replaced.

How to Reset the Toner on Brother HL-L2370DW

After installing a brand new toner cartridge, the printer usually spots it by itself and takes care of the toner warning automatically. Sometimes though it needs a little bit more time, and the message not, go away right away, like it should. If it keeps showing a “Toner Low” or “Replace Toner” message after you put in a fresh cartridge, especially when using a compatible or third party toner, you might need to reset the toner counter manually. Sometimes the whole thing, acts like it didn’t notice the new supply, so it won’t stop the alert.

Toner reset steps:

1. Make sure the printer is powered on, and yes the front cover is closed (fully).
2. Press the Go button (sometimes it’s also called power/resume), and hold it down.
3. Keep holding while the LCD goes through those little messages, about 2 seconds later it should say “Accepted” or the toner warning will just go away.
4. Then let go.

Alternative method (through Menu):

1. Open the printer front cover, but don’t take off the toner or the drum, ok.
2. While the cover is still open, press and keep holding the Go button for about 4 seconds until all the indicator lights come on, every single one.
3. Close the front cover again.
4. Now the toner counter is reset.

Important: Reset the toner counter only after you install a new cartridge. If you reset it on a cartridge that’s truly depleted, it will not restore toner, it only clears the software warning. If you keep printing with an empty cartridge, it can end up damaging the drum unit.

How to Reset the Drum on Brother HL-L2370DW

The drum unit (DR-730) keeps count of its own page totals separate from the toner cartridge. When that drum counter hits it’s expected life, roughly ~12,000 pages , the printer will show a “Drum End Soon” or a “Replace Drum” message. After you put in a fresh drum unit, you have to reset the drum counter yourself, it does not do that automatically.

If you skip the drum reset after installing a new drum unit , that warning can stay there, even though the drum is actually new.

Drum reset steps:

1. Press Menu on the printer’s control panel.
2. Use the arrow keys to navigate to Machine Info, then press OK.
3. Navigate to Parts Life, then press OK. (On some firmware versions, the path may be Menu > Machine Info > Reset Parts Life)
4. Navigate to Drum, then press OK.
5. Press OK again (or Yes when prompted) to confirm the drum counter reset.
6. The display will return to the home screen with the drum warning cleared.

Alternative front-cover method:

1. Open the front cover of the printer.
2. Press and hold the Go button for approximately 4 seconds until all indicator lights illuminate simultaneously.
3. Close the front cover.

Only reset the drum counter when you have physically installed a brand new drum unit. The drum counter is there to warn you that the drum is slowly reaching the end of its usable life. If you reset it too early, then the warning won’t show up when the drum really needs replacement, and that can make the print quality degrade quietly, without you noticing.

Compatible vs OEM Toner — What to Know

When you’re buying a replacement toner for the HL-L2370DW you basically have two main directions you can take, either OEM cartridges made by Brother, or a compatible/remanufactured option from other companies, in other words third parties.

OEM Brother Toner (TN-730 / TN-760)

Brother’s own toner cartridges are made to play nicely with the printer’s toner detection system, so in general you don’t need to do any manual resets after you install them. They usually deliver page yields pretty close to what’s advertised, and there’s also less chance you’ll run into issues that could complicate warranty claims related to the toner itself.

The downside, of course, is money. OEM cartridges are typically more costly per page compared with the cheaper compatible alternatives.

Compatible (Third-Party) Toner

These cartridges come from firms that aren’t Brother, but they’re engineered to fit the same machine, and do the same type of work. Still though, quality can be kind of everywhere depending on the maker so you might notice, big differences from one vendor to the next.

Potential advantages:

• Lower upfront cost, sometimes significantly so
• High-yield options available from some brands
• Widely available through major retailers

Potential downsides:

• May trigger “Replace Toner” warnings even when full, requiring a manual reset (see toner reset section above)
• Page yield may fall short of advertised numbers
• Toner powder quality inconsistencies can sometimes affect print density or, in rare cases, cause residue buildup on the drum

Bottom line: Compatible toners work for many people without any real trouble. If you try one and you see a false toner warning, then that manual reset process listed above should clear it up. Just choose the brands that have solid reviews and really plain return policies, and generally stay away from the cheapest, unbranded cartridge options.

A quick note on warranty: Brother warranty isn’t meant to cover harm that shows up because of using non-OEM supplies, though just putting in a compatible toner doesn’t automatically mean the whole printer warranty is gone. What really counts is whether the damage can be pointed back, traced directly to that third party cartridge, not just sort of loosely related or vaguely.

What Is the HL-L2370DWXL?

The Brother HL-L2370DWXL isn’t some other printer exactly. It’s basically the very same Brother HL-L2370DW laser model you’d find on its own, just packaged as a set that also has a high-yield TN-760 toner cartridge, already sitting in the box, so you can start faster.

That “XL” part here , well it’s not really a hardware bump or a speed upgrade or anything like that. It’s really just shorthand for the bundled high-yield toner. In practice the machine itself is mechanically and functionally the same as the standard HL-L2370DW, in every way that matters : same rated output, same wireless plus Ethernet setup, same automatic duplex printing, and the same driver compatibility across operating systems.

So why does it exist? Mostly because Brother (and the retailers) sell the XL package as a kind of value deal for people who want the full-yield cartridge up front, instead of the reduced starter toner that arrives with the base model. And that TN-760 in the HL-L2370DWXL box is not some secret special version—it matches the retail TN-760 cartridge you can buy separately.

If you have an HL-L2370DWXL, then all toner replacement steps and reset instructions from this guide apply to your unit as well. When the included TN-760 eventually runs dry, you can swap it for a standard TN-760, or if your usage is lighter you can choose the TN-730 instead.

FAQs

How do I know if my toner really needs to be replaced, like not just “almost”? Usually the printer LCD starts telling you pretty early. It may show “Toner Low” first, then after that comes “Replace Toner” when the cartridge is close to or at the end of its life. And yeah sometimes it’s not even a prompt, you might just see faded text, light streaks, or a weird uneven print density before any message appears. A “Toner Low” warning doesn’t automatically mean the cartridge is instantly empty, you typically still get a few hundred pages left at that stage.

Can I use TN-730 and TN-760 like they are the same. Both cartridges are physically identical, and they should fit into the same drum unit in the HL-L2370DW. The only real difference is the page yield. TN-730 gives you about ~1,200 pages and TN-760 gives about ~3,000 pages. So you can swap between them freely whenever you’re doing a replacement, no special order or anything.

How long does the drum unit last compared to the toner? The DR-730 drum unit is rated for around 12,000 pages. Meanwhile TN-760 toner yields roughly 3,000 pages. So in real life you’ll replace toner maybe 4 times for every one drum unit replacement. Also important: swapping toner does not reset the drum counter. They’re tracked separately, which is where people get tripped up sometimes.

Why is my printer still showing “Replace Toner” after I installed a fresh cartridge? This tends to happen when you’re using a compatible, or third-party toner where the printer chip doesn’t treat it as a brand new item right away. Go ahead and do the toner reset steps from the “How to Reset the Toner” section. If it still won’t clear, double check that the cartridge is fully seated in the drum unit. You should feel a firm click, not just “kinda” placed.

Can you shake the toner cartridge to pull a few more pages out of it? Yeah, but gently, not like you’re trying to fix the thing or anything. If you get a “Toner Low” alert, you can take the cartridge out and rock it side to side a couple of times. That may sort of help the remaining toner redistribute, and it can extend the usable lifespan just a bit. Usually it gives you only a modest extra number of pages. It’s basically a temporary fix, the cartridge still will need replacing pretty soon after that.

What about the drum warning then,when it shows up but not the toner one? That drum warning, like “Drum End Soon” or “Replace Drum”, is different from the toner warning. It’s pointing to the DR-730 drum unit, not the toner cartridge. In other words the drum is nearing the end of its rated life. You may be able to keep printing for a bit after the message appears, but the print quality might start getting worse, like lighter areas or faded streaks. You’ll want to replace the DR-730 drum unit and reset the drum counter the way this guide explains.

No , the Brother HL-L2370DW isn’t a color printer. like, it truly doesn’t do color at all. The HL-L2370DW prints only black and white, and honestly that means it’s a monochrome laser device. So, there aren’t any color toner cartridges neither, and there also isn’t a color printhead, or at least not one that it will use. It wont output in color even if you upload or send a file that’s supposed to look really colorful. If your document has any color at all, the printer sort of translates the whole document into grayscale first, before it prints.
