Your needs, this model
Does it fit your priorities?
Can I print color Legal documents automatically on both sides over USB at 3,000 monthly pages?
Yes with earlier references enabled and compatible computer software. Legal supports the main drawer and included duplex path in this exact dn configuration.
Explore this need in the finder →Can it supply 500 included Letter sheets without a paper accessory?
No. The base has a 250-sheet stack plus one manual sheet. The larger duo assembly is optional.
Explore this need in the finder →Can I choose it as a monochrome printer because it can print black-only documents?
No for the monochrome-printer requirement. This is a color print engine; a black-only job setting does not change its hardware class.
Explore this need in the finder →The duplex configuration for a modest color workgroup
The Lexmark CS310dn adds an important everyday capability to this small-workgroup color platform: automatic printing on both sides. That is a real distinction from the one-sided CS310n, rather than a software setting that makes the two variants interchangeable. This reference covers discontinued US part 28C0050 with its documented base paper arrangement and wired interfaces.
A sensible use is a team producing ordinary color documents within Lexmark's recommended 500–5,000 monthly printed pages. The separate 60,000-page maximum duty figure should not be treated as a routine allowance. Before considering an earlier machine, verify its actual part, condition, compatible software and regional consumable requirements. The original specification does not establish the contents or service terms of today's offer.
One-sided and duplex rates describe different modes
Lexmark declares up to 25 one-sided Letter pages per minute in black or color. Automatic two-sided output is separately rated at 12 Letter sides per minute. A long duplex document therefore should not be planned using the simplex figure alone. These are maker declarations rather than test measurements from this article, and the number of short submissions or complex pages can matter as much as maximum continuous output.
The original paper table positively supports Letter, Legal and A4 in the included drawer and duplex path. That combination is more informative than a general claim that the printer accepts Legal paper: the chosen size must actually fit the automatic two-sided route. Suitable envelopes use a separate one-sided manual routine and do not inherit ordinary-paper duplex support.
Understand what 250+1 includes
The base has a 250-sheet main drawer and one-sheet manual feeder, quoted at the manufacturer's 20-pound or 75-gsm paper basis. The plus-one source is useful for an occasional suitable special sheet, but is not another full drawer. When calculating an ordinary Letter, Legal or A4 stack, the main drawer provides 250 sheets. Output capacity is separately 125 sheets.
Legal loading requires the appropriate guide extension, and settings must match the actual size and type. The guide gives different letterhead orientations for one-sided and two-sided printing, a detail worth checking before putting preprinted stock into a shared queue. Do not assume that a full ordinary-paper stack makes every thickness or coated material suitable.
The optional duo assembly supplies an additional 550-sheet drawer and 100-sheet multipurpose feeder, taking the maximum to 900+1. That is a separate physical purchase or installed accessory. Confirm the hardware and installed-options setting in the driver if the larger arrangement is essential, instead of relying on a family capacity headline.
Wired connections and shared mobile printing
USB Type-B explicitly supports connection to a computer. The US page also says Direct USB No; that separate field should not be interpreted as absence of the computer port. Ethernet is a 10/100 interface described as working with a 1000Base-T network. It should not be promoted as a gigabit-speed printer interface.
Wireless requires an optional MarkNet adapter. AirPrint and Mopria appear in the scoped guide as suitable shared-network mobile routines, while the exact product record also names AirPrint. Use an appropriate common network and compatible applications; a direct USB cable to one computer does not itself provide mobile discovery. A complete confidential PIN-release workflow is not established by the read CS310 sections, so a security requirement needs its own exact confirmation.
Compare its supplied toner and ongoing requirements
The US CS310dn ships with toner declared at 1,400 pages for black and each color, different from the smaller CS310n starter set. Specific US replacements include 70C1HK0 black at 4,000 pages and 70C1HC0, 70C1HM0 and 70C1HY0 colors at 3,000 each. Those are ISO/IEC 19798 declarations, subject to actual use, regional cartridge restrictions and Return Program conditions. Separate imaging and developer components are additional maintenance considerations; yield figures do not establish current cost per page.
This remains a print-only color engine, without scanning, copying or fax. The body is 17.4 inches wide, 16.0 deep and 11.5 high at 44.8 pounds. Allow operating access and extended paper guides, and check the actual electrical label and cord. Its useful combination is included duplex with moderate color volume, provided the wired base configuration and small main stack fit the workflow.

Paper, software and setup details
Print-rate conditions
Maximum 25 one-sided black or color Letter pages/minute; automatic print duplex separately 12 Letter sides/minute for black or color. Manufacturer mode declarations, not measured throughput.
Paper handling
Included 250-sheet main drawer plus a one-sheet manual feeder: 250+1 headline sheets at 20 lb/75 gsm, with a 250-sheet ordinary main stack. Letter/Legal/A4 support the drawer. Suitable envelopes use the separate one-sided manual-feed routine. Optional input is not included. Integrated automatic print duplex supports Letter, Legal and A4. Optional duo assembly raises input to 900+1 and is not included.
Scanning arrangement
Explicitly print-only color laser hardware. No paper scanner, document feeder, copier or fax. A control screen and generic print/scan software names do not supply capture hardware.
Computer and mobile connections
Included USB Type-B computer interface and wired Ethernet. Wireless requires a separate MarkNet option; no included Wi-Fi Direct arrangement is established. AirPrint/Mopria use the documented suitable shared-network arrangement, not a USB-only computer cable.
Supplies and declared yields
Supplied US black/cyan/magenta/yellow toner each declared at 1,400 pages, unlike the CS310n starter set. US replacements include 70C1HK0 black at 4,000 pages and 70C1HC0/70C1HM0/70C1HY0 cyan/magenta/yellow at 3,000 each. Declared continuous black/composite-color yields under ISO/IEC 19798, not measured costs. Match the geographical cartridge restriction and Return Program terms. Imaging/developer components are separate, with estimates depending on stated job and coverage assumptions.
Software and support
The exact scoped guide documents network AirPrint/Mopria and compatible applications. Check current drivers and firmware; no retired cloud service is promised. Confidential PIN release is not established for this exact configuration by the read operative sections.
Electrical edition and setup
Earlier US reference; verify actual regional part, included hardware and current software. Nominal mains input is unestablished, so inspect the actual electrical label and proper cord. Body dimensions exclude loading/service access and extended paper guides.
