Main trade-off
Brother HL-L5210DW
A long ordinary-paper job can need a main-tray refill even when the output is being collected regularly.
Head-to-head
Choose HL-L6210DW when a 520-sheet main tray removes a regular paper refill or your routine workload exceeds 5,000 pages a month, within its 8,000-page recommendation. Choose HL-L5210DW when a 250-sheet main tray is enough and you want a lower, lighter body. Both have 150-sheet face-down output, so the bigger input does not make a 500-sheet run unattended.
Before you choose
If you print 500 single-sided handouts while preparing a class or meeting, the 6210 main tray can hold the paper in one load. The 5210 main tray needs two loads. But both output bins hold only 150 ordinary sheets, so both need collection during that run. Buy the 6210 to remove the input refill, not to leave the whole job unattended. Printing those 500 pages duplex reduces the sheet count to 250, which changes the input advantage.
What this is based on
At 20 lb, 500 single-sided pages use 500 sheets. Main-tray loads are ceiling(500/520) = 1 and ceiling(500/250) = 2. ceiling(500/150) = 4 output batches on both, meaning at least three interim collections. For 500 duplex pages, 250 sheets fit either main tray. MP tray held for alternate stock.
Main trade-off
A long ordinary-paper job can need a main-tray refill even when the output is being collected regularly.
Main trade-off
The larger main tray does not enlarge the output bin. Its body is 1.3 inches higher and 5.7 lb heavier.


The HL-L6210DW holds more paper in the same footprint, but output stays at 150 sheets. Compare refills, cabinet height and what is included in the box.
These are neighboring Brother business monochrome print-only models with the same base dimensions and familiar network connections. A real buyer needs to know whether the larger paper supply changes the daily job enough to justify the upgrade.
Winner by situation
6210 removes the input refill. Both still need interim output collection.
That is 250 sheets, which fits either main tray at the stated paper weight.
Above 5210 recommended 5,000 maximum and within 6210 recommended 8,000.
5210 is 1.3 inches lower. Check operating clearance before fitting either under a shelf.

A shared office may have enough floor or worktop area but limited clearance below a shelf. These printers use the same 14.7 by 15.3-inch base dimensions. The 6210 adds 1.3 inches of closed-body height and 5.7 lb. If you rarely refill the 5210 during a job, its lower body can be the more useful fit. If refills happen daily and the height is available, the 6210 gains capacity without a wider or deeper body.
11.4 - 10.1 = 1.3 inches and 29.8 - 24.1 = 5.7 lb. Closed dimensions exclude operating and ventilation clearance. These are standard single-tray DW packages, not DWT.
If the upgrade is meant to avoid an early toner purchase, check the included cartridge. Both standard boxes supply TN920 with the same 3,000-page ISO claim. The 6210 higher-capacity replacement is a later purchase. That can still suit a sustained high-volume office, but it does not give a light-use home office six times as much starting toner. Compare the current complete costs before letting the replacement-yield headline decide.
Both include a 3,000-page ISO19752 TN920. HL6210 supports an optional 18,000-page-rated replacement. No current cartridge cost, household yield or ownership-cost saving is inferred.

Brother, HL-L5210DW
Keep the body 1.3 inches lower when a 250-sheet main tray covers the usual job.

Brother, HL-L6210DW
Load up to 520 ordinary sheets in the main tray, while still collecting output at its 150-sheet limit.
Meaningful differences
| What changes | Brother HL-L5210DW | Brother HL-L6210DW | Why it matters |
|---|---|---|---|
| Main-tray print supply | 250-sheet main tray plus 100-sheet multipurpose tray. Face-down output holds 150 sheets, based on 20 lb paper. | The standard HL-L6210DW has a 520-sheet main tray plus 100-sheet multipurpose tray. Face-down output holds 150 sheets at 20 lb. | A bigger input reduces refills, while equal output limits preserve collection visits. |
| Cabinet and worktop fit | Closed body 14.7 x 15.3 x 10.1 inches and weight 24.1 lb. | Closed body 14.7 x 15.3 x 11.4 inches and weight 29.8 lb. This is the DW single-tray model. | The upgrade uses the same footprint but more vertical space. Leave clearance for paper and maintenance. |
| Supplied versus replacement toner | Includes TN920 rated at 3,000 ISO19752 pages. Higher-yield replacements are optional. | Includes TN920 rated at 3,000 ISO19752 pages. An 18,000-page replacement is available separately. | Do not value the standard package as though it contains the largest replacement cartridge. |
| Sustained workload | Recommended monthly maximum 5,000 pages. | Recommended monthly maximum 8,000 pages. | This matters for repeat workload. It does not predict that either printer fails immediately beyond the recommendation. |
What you give up
Recommendation switch
Choose Brother HL-L5210DW. 5210 avoids buying capacity that removes no regular refill.
Choose Brother HL-L6210DW. 6210 addresses those particular capacity and workload constraints.
Choose neither. Both documented output bins hold 150 sheets.
What matters in practice
You want to print a long packet while doing other work, but a larger input tray may solve refills without solving the need to collect printed sheets.
