Which wired monochrome printer fits a workgroup that uses automatic duplex?

The advantages and the compromises

The key details

Model covered

M602x

Main functions

Print only; monochrome laser

Print output

Up to 52 ppm Letter / 50 ppm A4

Two-sided printing

Automatic duplex; 1,100-sheet standard input and 600-sheet output

Keep the M602x suffix tied to its configuration

HP's M601/M602/M603 guide distinguishes the M602x from the nearby M602dn and M602n. The M602x includes automatic duplex and an additional 500-sheet Tray 3; the M602dn has duplex without that third tray, while the M602n lacks both as standard features. That distinction changes paper capacity and everyday handling, so a listing that only says M602 should not be treated as the same package. Match the complete model label and product CE993A before comparing this profile with a particular device.

Three standard trays prioritize uninterrupted output

The documented standard supply is a 100-sheet multipurpose Tray 1 plus two 500-sheet trays, for 1,100 sheets of input. HP lists both a 500-sheet face-down bin and a 100-sheet face-up output path. This is a meaningful advantage for a shared queue that runs through ordinary paper quickly or needs separate stocks available. It is also a larger machine and a more involved paper system than a compact desk printer. Inspect each tray, pickup path, and output route on any used unit rather than assuming the paper hardware remains complete.

Speed and monthly guidance describe a workgroup role

HP rates the M602x at up to 52 pages per minute on Letter and 50 on A4. Those figures are manufacturer ratings, not a promise that every host, complex file, or aging unit will sustain the same pace. The 3,000–15,000 monthly recommendation is the more useful guide to intended routine workload. HP's separate 225,000-page duty-cycle figure is a maximum ceiling and should not be substituted for the recommended range. Estimate the office's normal use and check the page count and maintenance history of the exact machine under consideration.

Automatic duplex is standard; wireless is an add-on

HP documents automatic duplex as standard, so the printer turns sheets during two-sided print jobs without a person reloading the stack. That suits reports and recurring packets better than manual duplex. The built-in connections are Gigabit Ethernet, Hi-Speed USB 2.0, and host USB. Wireless is not built in to the listed M602x configuration and requires an optional accessory. An office should plan around the actual wired ports unless the specific unit includes and supports the wireless option; the M602x name alone does not prove that accessory is fitted.

Treat its discontinued status and listing separately

HP marks this product discontinued. The saved Amazon page title and structured product fields match M602X and CE993A, which supports the exact-model destination, but that page is identified as a renewed-model listing and does not establish the condition or terms for every offer. Confirm the chassis label, tray configuration, duplex operation, toner, service history, and return policy on a specific unit. The cited technical sources establish the design and ratings; they do not establish present stock, price, or long-term supply availability.

How the alternatives change the decision

Compare the wired M4020ND or P3500DN for smaller paper reserves and lower documented ratings, or choose a current network model if support and supplies matter more than this discontinued platform.

A distinct M402 office printer

HP's saved product page identifies the M402dne as its own discontinued model, with product number C5J91A#BGJ. The name is easy to confuse with the earlier M401dne, but the packets distinguish them as separate generations rather than aliases. That matters because family suffixes can change ports, paper handling, and duplex equipment. Use the exact label on the device and match it to M402dne documentation; do not transfer an M401 fact simply because the names look close. The basic role is clear: black-and-white printing without a copier or scanner.

Speed and duplex suit routine office packets

HP rates this printer at up to 40 pages per minute on Letter paper and 38 on A4, and lists standard automatic duplex. Those specifications make it more suited to repeated forms, policies, and internal reports than a slower personal printer. The rate is a manufacturer maximum, not a promise for every driver, file, or first page. Automatic duplex removes the manual refeeding step for double-sided work, though buyers should still confirm that their paper size and driver setup support the jobs they intend to print.

A practical standard paper reserve

The source records a 100-sheet Tray 1, a 250-sheet Tray 2, 350 sheets of standard input in total, and a 150-sheet output bin. That gives a shared desk more room than a small single-tray personal printer while keeping the base configuration legible: the 350-sheet figure is standard, not an optional expansion. Tray capacity helps reduce attention spent reloading, but it does not determine whether a machine can handle a team's monthly workload by itself. Match paper size, media, and actual queue volume to the office routine.

Use the recommended range, not a ceiling

HP lists a recommended monthly volume of 750 to 4,000 pages. This range is the relevant planning figure for deciding whether the M402dne belongs in a lightly shared office or a busier department. A maximum duty-cycle number, even if present elsewhere in a product family document, is not a recommended target and is not used here as a quality claim. At the low end, buyers may prefer a smaller device; above the published range, compare a printer with a recommendation suited to the sustained queue rather than relying on a peak limit.

A wired connection is documented

HP lists Hi-Speed USB 2.0, host USB, and built-in Gigabit Ethernet for this configuration. Ethernet gives a direct wired route for a managed office network, and USB supports a local connection. The available exact-model packet does not establish built-in wireless, so this review does not treat Wi-Fi as present or absent. If wireless placement is essential, check the maker's exact configuration documentation or choose a model with explicitly confirmed built-in Wi-Fi. Also verify current operating-system and driver support for the computers that will use a discontinued printer.

Check the individual unit and supply path

The official specifications establish original features, not the condition of a machine offered today. HP marks the M402dne discontinued, and the saved historical ASIN B01ILQWV9C was not proven to identify this exact model. The tagged Amazon search is therefore a model search, not an endorsement of any result. Before purchase, ask for a clear model-label photo, print count, working-status details, included toner information, and return terms. Separately check supply and service availability with sources you trust; neither current stock nor an acceptable operating cost is established by this packet.

How the alternatives change the decision

The Lexmark MS810dtn offers a much larger 1,200-sheet standard input and a higher 3,000–50,000 page recommendation. The M402dne is the narrower fit when its 750–4,000 page range and 350-sheet base supply are closer to the real queue.

Capacity matters only for a real office queue

Lexmark's recommended monthly range begins at 3,000 pages and extends to 50,000, which places the MS810dtn far beyond a casual desk printer. A department that regularly sends large black-and-white packets can benefit from that workload class. For a household or small office printing a few hundred pages, the large chassis and supply system add complexity without solving a frequent problem. Decide from the actual monthly queue and shared users, not from the separate 250,000-page duty-cycle maximum, which describes a ceiling rather than a recommendation.

The dtn suffix brings an included second tray

The MS810dtn has a 550-sheet main tray, an included additional 550-sheet tray, and a 100-sheet multipurpose feeder, for 1,200 sheets of standard input. Lexmark's MS810de packet documents a different base tray arrangement, so the dtn suffix matters when comparing a listing. Its 550-sheet standard output bin also provides more room for long jobs. Treat these as features of the exact dtn configuration, and confirm the part number 40G0410 on the machine or seller documentation before paying for a used unit.

Fast monochrome output with automatic duplex

Lexmark rates the MS810dtn at up to 55 pages per minute on Letter paper and lists integrated automatic duplex. This combination is relevant to offices that distribute recurring reports, invoices, and internal forms on both sides. Duplex removes the manual paper-turning step, while speed helps explain the model's intended class. The manufacturer rate remains a maximum under test conditions; complex documents, first-page timing, network load, and setup can change an actual job. It is not a guarantee that every office will see 55 pages each minute.

A straightforward wired shared setup

Lexmark lists Gigabit Ethernet and USB 2.0 for this model, allowing a wired network share or a direct local connection. The saved exact-model material does not establish built-in Wi-Fi, so a wireless requirement should not be treated as met by the dtn. A managed office should confirm that its print server, drivers, security policy, and available ports fit the intended setup. Those checks concern the buyer's own environment and the specific unit; the source packet does not validate current compatibility with a particular network or computer.

Distinguish the dtn from adjacent variants

Lexmark's saved documentation identifies the dtn as a configuration with a 2.4-inch color LCD and the included second 550-sheet tray. The closely related MS810de instead has a larger 4.3-inch touchscreen and lacks that standard included tray in its packet. A seller title that says only MS810 is not enough to establish the dtn configuration. Check the full suffix and U.S. part number, and verify that the second tray and intended paper path are actually present on the individual machine.

Lifecycle and ownership need their own checks

The source packet does not establish whether Lexmark currently supports the MS810dtn, whether replacement parts or supplies are easy to obtain, or whether a particular marketplace unit is operational. The historical ASIN B00Q2B7J46 also remains unverified for exact-model identity. Use the tagged model-and-part-number search as a search, not a direct product claim. Ask the seller for the full part number, a working print sample, page count, included toner details, and return terms, then check current supply and service availability independently before committing to a high-volume role.

How the alternatives change the decision

The HP M402dne is a smaller wired monochrome option with a 350-sheet standard input and 750–4,000 page recommended range. It makes more sense when the MS810dtn's 1,200-sheet supply and high-volume rating would go unused.
