Office Products · SCENARIO ANSWER

Which monochrome fax MFP handles automatic duplex for a small office?

Question: I need black-and-white printing, fax, and automatic two-sided output. I can use either wired or wireless networking and have no fixed monthly-volume target. Which exact MFPs should I compare?

The Brother MFC-L5800DW, Brother MFC-8710DW, and HP LaserJet 3390 all document monochrome print, copy, scan, fax, and automatic duplex printing. The L5800DW is rated up to 42 ppm and includes Wi-Fi and Ethernet, with an ADF that is not confirmed for duplex scanning. The 8710DW is rated up to 40 ppm with Wi-Fi and Ethernet, while its duplex scan behavior and monthly range remain unreported. HP's 3390 is a discontinued wired model rated up to 22 ppm with a 1,000–3,000 page recommendation. This is a curated comparison of these exact products.

THE SHORT ANSWER

What we would do

The MFC-L5800DW is the fastest listed option and has the clearest documented feature set for fax, automatic print duplex, and Wi-Fi or Ethernet; its 70-sheet ADF does not have confirmed duplex scanning, and Brother gives only an upper monthly recommendation of 3,500 pages. The MFC-8710DW is another fast networked choice with automatic duplex for printing and copying, but no monthly recommendation or duplex ADF scanning is established. The LaserJet 3390 has a smaller 22 ppm rating and an explicit workload range, but HP marks it discontinued and documents wired rather than built-in wireless networking. Check software, consumables, and the condition of any specific unit.

A monochrome office MFP with fax

Brother's exact product page identifies the MFC-8710DW as a monochrome multifunction device that prints, copies, scans, and faxes. That breadth suits an office that needs one machine for ordinary pages and fax traffic rather than a dedicated print-only device. The suffix is meaningful: nearby models may have different wireless or paper-handling details. Confirm the full MFC-8710DW label before comparing a listing. The saved packet does not connect the historical candidate ASIN to a verified current Amazon offer, so the product link remains an exact-model search.

Relevant to your automatic duplex required answer

Speed and duplex cover output and copying

Brother rates print and copy output up to 40 pages per minute and documents automatic duplex for both. That can help with repeated two-sided forms or copy packets in a shared office, reducing the need for someone to turn pages between sides. The stated rate is a manufacturer rating rather than a prediction for every document or a test of a current machine. It applies to output handling; it should not be used to claim that the scanner feeder automatically captures both sides of an original.

A legal-size flatbed and feeder handle originals

The MFC-8710DW provides a legal-size flatbed scanner and a 50-page ADF. The flatbed is useful for a single page or larger original, while the feeder can take a stack of loose sheets. Brother's reviewed source does not confirm duplex scanning on this exact model. Buyers that regularly archive two-sided originals should check the operation directly or compare a model whose specifications explicitly state duplex ADF scanning. A feeder capacity alone describes the stack size, not the side-handling mechanism or scan speed.

Several connection paths support a shared desk

Brother lists 802.11b/g/n Wi-Fi, Ethernet, and USB 2.0. That provides wireless and wired network choices plus a direct connection. Whether the older machine can integrate with a particular current router, computer, or driver is not answered by the original interface list, so compatibility should be checked separately. The source does not establish a recommended monthly volume, and a 40 ppm rate is not a replacement for workload guidance. Avoid sizing a department by speed alone when duty and service expectations matter.

Do not infer scan duplex or workload limits

Two key facts remain open in the saved exact-model packet: duplex ADF scanning and recommended monthly volume. The profile preserves both volume endpoints as unknown and does not claim a duplex scan feature. These omissions matter for two-sided records and for offices comparing intended usage. If either is decisive, request a manufacturer document for the exact configuration or choose a model that states it clearly. A maximum duty cycle, if a seller repeats one, is not a recommendation and does not reveal the maintenance history of a particular printer.

Relevant to your fax function and automatic duplex required answer

Check condition and support on an older offer

The saved historical Amazon page for ASIN B07H7Q7TZX returned a cache miss, so it is not used as identity proof or a direct purchase link. The tagged search names the MFC-8710DW. Before choosing a used example, confirm the label, run a print and copy test, test fax and scanning, verify Wi-Fi or Ethernet on the intended network, inspect the ADF path, and ask about supplies, page count, and return terms. None of those checks has been performed on a particular unit in this review.

How the alternatives change the decision

Compare the MFC-L5800DW for a 42 ppm model with a documented 70-sheet feeder and published volume ceiling, or the MFC-9560CDW for confirmed duplex ADF scanning in color.

Before you decide

Does the MFC-8710DW include fax?

Yes. Brother lists fax alongside print, copy, and scan functions for this exact model.

Does its ADF scan both sides automatically?

The saved Brother product page confirms a 50-page ADF but does not establish duplex scanning for the MFC-8710DW.

What interfaces are included?

Brother documents 802.11b/g/n Wi-Fi, Ethernet, and USB 2.0 for this model.

The decision for your answers

The MFC-8710DW offers a clear mono fax-and-duplex output workflow. Confirm scan-side behavior, workload needs, software, and condition before relying on it as a current office device.

One device for the office document cycle

Brother lists print, copy, scan, and fax for the MFC-L5800DW. That broad function set can make sense where a shared desk handles both output and incoming or outgoing documents. Its suitability comes from the combination rather than from a single headline speed. A household that rarely copies or faxes may prefer a simpler printer, while a small workgroup can avoid moving pages between several machines. The model identity is tied to the L5800DW suffix; nearby Brother MFC models have different feeder or scanning details, so compare the exact name rather than a shortened family title.

Relevant to your automatic duplex required answer

Fast monochrome output with automatic page turning

Brother rates the printer up to 42 pages per minute and specifies automatic duplex printing. Those are relevant facts for a queue of recurring contracts, internal reports, or multipage forms where black output and two-sided pages are common. The rated maximum does not promise that every file will print at that rate, and the source is not a hands-on benchmark. Automatic duplex addresses the printed sheet only. It should not be expanded into a claim that the scanner can also turn a two-sided original, because the saved product specification does not establish that capability.

The feeder helps with stacks but not both sides

The MFC-L5800DW pairs a flatbed with a 70-sheet automatic document feeder. That gives the operator a glass surface for a book or single delicate page and a feeder for a stack of loose originals. Brother does not document duplex scanning on this exact model in the reviewed material. Customers who routinely archive both sides of forms may need to turn each original manually or consider an exact model that explicitly lists duplex scanning. The feeder capacity describes how many sheets it can hold, not an unattended two-sided scan workflow.

Networking and paper supply suit shared placement

Brother lists built-in wireless, Ethernet, and USB, so this model can be placed according to an existing network rather than a single fixed workstation. The standard input combines a 250-sheet tray and a 50-sheet multipurpose tray for 300 sheets total, with a 150-sheet output capacity. That provides more reserve than a compact home printer but still needs refilling in busy departments. Confirm the network setup and tray condition on an actual used unit; manufacturer capabilities do not prove that an individual device has working radios, ports, or paper-feed parts.

The volume statement has a one-sided boundary

Brother describes recommended monthly use up to 3,500 pages. The packet does not establish a lower limit, so the matching profile leaves the lower endpoint unknown. This is enough to show that Brother publishes a ceiling useful to a workgroup comparison, but it should not be rewritten as an exact range beginning at zero or at an invented page count. Compare expected work against the confirmed upper value and use the maker's complete current guidance if workload sizing is critical. A maximum duty cycle, where shown separately, would not replace a recommended workload.

Relevant to your fax function answer

Verify the unit, software, and offer details

The saved historical Amazon page associates ASIN B01824ZCBM with the MFC-L5800DW, but it was captured nine months earlier and showed no featured offer. That is identity context, not evidence of a current offer, price, stock, or seller condition. The product destination therefore searches the exact model instead of sending a buyer to a stale direct listing. Before buying a used or renewed example, confirm the label, print a duplex sample, test fax and scanning, check the feeder rollers, inspect toner state, and verify that the intended computers can use the available software.

How the alternatives change the decision

Compare a model whose exact manufacturer specifications confirm single-pass duplex scanning if that workflow is central, or the DCP-L2550DW if fax is not part of the workflow.

Before you decide

Does the MFC-L5800DW scan both sides automatically?

The saved Brother materials confirm a 70-sheet ADF but do not establish duplex scanning for this exact model.

What network connections are documented?

Brother lists built-in Wi-Fi, Ethernet, and USB, giving this mono MFP both shared-network and direct-connection options.

What monthly volume does Brother recommend?

The saved source states a recommended ceiling up to 3,500 pages per month, but it does not provide a lower endpoint.

The decision for your answers

The MFC-L5800DW combines speed, fax, automatic print duplex, and flexible networking. Its feeder is not a substitute for confirmed duplex scanning, and the monthly guidance remains incomplete at the lower end.

A full mono MFP rather than a printer-only shortcut

HP describes the LaserJet 3390 as an all-in-one machine that prints, copies, scans, and faxes. That matters when the intended desk handles originals as often as it produces pages. The flatbed supports single pages and material that should not be fed, while the 50-sheet ADF can move through a stack of loose originals. The saved product identity is specifically 3390 with base product Q6500A. HP's 3392 is a distinct model with a different configuration, so an abbreviated 3390-series listing is not enough to establish which machine is offered.

Relevant to your automatic duplex required answer

Automatic duplex pairs with a moderate rated speed

HP lists up to 22 pages per minute on Letter and 21 on A4, along with standard automatic duplex printing. The rate is a manufacturer rating, not an estimate for a used device or a scan-and-print workflow. Automatic two-sided printing can reduce paper handling for repeated office documents, but does not imply duplex scanning: the packet establishes an ADF and flatbed, not a double-sided ADF mechanism. If two-sided originals are common, ask the seller to demonstrate that exact intake process rather than infer it from the printer's duplex feature.

Capacity is defined, with a small priority slot

The standard paper path includes a 250-sheet input tray and a one-sheet priority slot, with output rated at 125 sheets. This is a useful arrangement for an office that keeps a main paper supply loaded and occasionally feeds a special page. It is not the same as a larger multi-drawer workgroup setup. Capacity values describe the model specification; they do not tell whether rollers, trays, or sensors on a particular older machine remain in good shape. Check feed behavior across both paths and confirm the included parts on any offer.

Ethernet supports wired sharing, not Wi-Fi

HP's model-specific connectivity material lists 10/100 Ethernet and USB 2.0. It does not document built-in wireless on the 3390. Ethernet can make the device available on a wired local network, while USB is the direct host option; neither should be stretched into a promise that a present office's print server or operating systems will support it. A buyer that requires printer-native Wi-Fi should choose a separately verified wireless configuration. The distinction is especially important when listings group several LaserJet models under one family heading.

A published range helps with workload fit

HP recommends 1,000 to 3,000 pages per month for the 3390. This is a better comparison point for routine work than a maximum duty-cycle number. It suggests a shared office use case but does not certify that a particular aging device can sustain the same activity today. Use expected pages as one input alongside function needs, connection, and the condition of the scan, fax, and duplex mechanisms. HP has marked the product discontinued; the saved material does not establish the availability of original supplies, replacement parts, or compatible software now.

Relevant to your fax function answer

Exact variant and current condition remain decisive

The historical ASIN B000E6Z4E2 is not linked directly because its exact current relationship to a live offer has not been established. The search destination names the 3390 and product number Q6500A. Before buying, confirm the label, test a print, copy, fax, and scan job, inspect both sides of the ADF path and automatic duplex, ask about page count and toner, and check the return window. These are sensible checks for an older MFP, not claims that any individual unit was tested. For built-in Wi-Fi, compare a different exact model.

How the alternatives change the decision

Compare a current exact mono MFP if wireless networking or present software support is essential; the Brother MFC-L5800DW is a faster documented fax model with Wi-Fi.

Before you decide

Does the LaserJet 3390 have fax?

Yes. HP identifies the exact 3390 as a print, copy, scan, and fax all-in-one model.

Can it print both sides automatically?

Yes. HP's 3390 specification lists standard automatic duplex printing.

Is the 3390 the same configuration as the 3392?

No. HP's technical reference distinguishes the 3390 and 3392 feature sets, so verify the exact model label.

The decision for your answers

The 3390 has a coherent wired office feature set on paper, including fax, an ADF, and automatic duplex. Its discontinued lifecycle and unverified current-unit details set the limits of a recommendation.

USEFUL FOLLOW-UPS

Questions to ask before you choose

Which model has the highest rated print speed?

Brother rates the MFC-L5800DW up to 42 ppm and the MFC-8710DW up to 40 ppm; HP rates the LaserJet 3390 up to 22 ppm on Letter.

Can any of these be assumed to scan both sides through the ADF?

No. The saved L5800DW and 8710DW materials do not establish duplex ADF scanning, and HP's 3390 packet confirms its feeder but not duplex scan behavior.

Which one has a published monthly range?

HP gives the 3390 a 1,000–3,000 page recommendation. Brother states an upper recommendation for the L5800DW but no lower endpoint; the 8710DW range is unknown.

Are the links verified offers for new machines?

No. They search by exact model and do not claim current stock, condition, included toner, software compatibility, or supply availability.
