Our take
Brother's U.S. specification identifies the MFC-8510DN as a monochrome laser multifunction model with print, copy, fax and color scan functions. The rated Letter print speed is up to 38 pages per minute. Automatic two-sided printing is standard, as are wired Ethernet and USB; the source does not list built-in Wi-Fi. A 250-sheet cassette, 50-sheet multipurpose feed and 35-sheet automatic document feeder support mixed paper and multi-page originals. Brother does not state a recommended monthly range in the reviewed specification. This is a useful feature combination for a wired office, provided an older discontinued platform fits the installation and support needs.
A wired office that wants fast mono documents, fax and automatic two-sided printing in one older multifunction unit..
Skip this model when wireless is required, when color printing is part of the job, or when current support and a manufacturer-recommended monthly range are essential.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Brother lists up to 38 ppm on Letter and standard automatic duplex for the exact MFC-8510DN.
- A 35-sheet ADF, 250-sheet cassette and 50-sheet multipurpose feed cover routine originals and media changes.
- Ethernet and USB give a documented shared-network path and a direct connection option.
What to weigh up
- Brother's reviewed specification does not list built-in Wi-Fi.
- A recommended monthly page range is not stated; do not treat the 38 ppm speed as workload guidance.
- This is a discontinued model, so verify driver support, service parts and the exact machine's condition.

Full review: how the features affect your choice
What the features mean for you
A wired monochrome office MFP
Brother identifies the MFC-8510DN as a monochrome laser multifunction device with printing, copying, faxing and color scanning. That makes it more suitable for a shared document station than a print-only HL-series machine, while keeping output itself monochrome. Brother's exact U.S. specification is the basis for these functions; names from nearby MFC models should not be used to fill gaps. For a small office that receives paper originals or sends faxes, the combined workflow can reduce device handoffs. Check the exact MFC-8510DN label because model suffixes in this family distinguish network and duplex configurations. ([Brother MFC-8510DN specifications](https://support.brother.com/g/b/spec.aspx?c=us&lang=en&prod=mfc8510dn_us)).
Rated speed and two-sided output
Brother rates the MFC-8510DN up to 38 pages per minute on Letter paper and lists automatic duplex printing. The speed is a manufacturer rating rather than a promise for a particular file, host, network or used unit. Automatic duplex can reduce manual page handling for recurring reports and forms, but buyers should confirm that the installed unit feeds both sides cleanly. Brother's page does not establish a separate manual-duplex mode, so that profile detail remains unknown. If most of the workload is color output, this monochrome engine is the wrong fit regardless of its speed. The rating does not establish recommended monthly capacity.
Paper routes and document feeding
The listed standard supply includes a 250-sheet cassette and a 50-sheet multipurpose feed, while the ADF holds 35 sheets. The cassette serves ordinary paper, and the multipurpose path can help with a separate paper type or occasional single-sheet work. The ADF supports multi-page copy, scan and fax jobs without placing each page on the glass. These are rated capacities, not a claim that every used listing includes intact trays or an ADF that feeds reliably. Inspect the cassette guides, pickup rollers, hinges and feeder path on the unit being considered, especially if staff will scan or fax stacks frequently.
Ethernet fits a wired shared queue
Brother lists Ethernet and USB for the MFC-8510DN. Ethernet allows several computers on a compatible office network to use a shared printer queue, while USB is a direct-host alternative. Built-in Wi-Fi is not listed in the reviewed exact-model specifications, so do not assume a wireless card or access point is part of the base configuration. Before choosing this older model, confirm that the intended operating systems still have a usable driver and that the network's security settings can support the printer. A current device's compatibility should be checked with the manufacturer rather than inferred from a historical speed rating.
A discontinued unit needs a practical check
Brother marks this generation as discontinued in its support catalog, and the page does not publish a recommended monthly range. That leaves useful boundaries: the 38 ppm figure describes rated speed, not how much routine work Brother recommends, and current supplies or service cannot be inferred from the original specification. Ask the seller for a clear model-label photo and a sample duplex page, and test copying, scanning, fax setup and Ethernet printing before putting it into a shared workflow. If predictable support or a volume recommendation is a purchase requirement, compare a current model with those facts documented.
Compare for your needs
For a wireless setup compare a Brother MFP whose exact suffix lists Wi-Fi; for workload planning choose a current model with a published recommended volume range.

Brother lists USB and wired Ethernet in the reviewed U.S. specification, not built-in Wi-Fi.
How fast is its Letter printing rated?
Brother lists a maximum rated speed of up to 38 pages per minute on Letter paper.
How much can the ADF hold?
The Brother specification lists a 35-sheet automatic document feeder.
What monthly workload does Brother recommend?
The reviewed exact-model specification does not give a recommended monthly range.

The decision
The MFC-8510DN pairs fast monochrome printing, fax, color scanning and automatic duplex with wired networking, while its age, lack of listed Wi-Fi and unstated recommended volume narrow its fit.
