Your needs, this model
Does it fit your priorities?
Can Ethernet combine automatic color duplex, PIN release and 350 included sheets at 4,500 monthly pages with flexible paper size?
Yes with compatible software and suitable ordinary paper. The integrated duplex mechanism and memory-based PIN routine are confirmed; the recommended ceiling is 4,700 pages/month. Exact duplex-size support requires separate confirmation.
Explore this need in the finder →Can USB supply 350 ordinary Legal sheets and occasional envelope jobs?
Yes for Legal simplex printing. The drawer and MP feeder supply 250 plus 100 ordinary sheets; suitable envelopes replace the MP load for a separate one-sided routine.
Explore this need in the finder →Does the reviewed evidence establish automatic Legal duplex specifically?
The automatic mechanism is confirmed, but the exact duplex-size subset is unestablished. The manual explicitly labels its size-table measurements as simplex, so a specific Legal duplex requirement cannot be verified from that table.

The Lexmark C534dn combines USB and Ethernet with an integrated automatic-duplex unit and a numeric keypad for documented confidential printing. US part 34A0150 fits a wired team producing color documents within the maker's 1,500–4,700 recommended monthly pages. It declares up to 24 black or 22 color one-sided Letter pages per minute.
The exact dn differs from the C534n in duplex hardware and its listed processor and memory configuration. It still has only 350 included ordinary-paper sheets across two sources. Wireless, additional paper hardware and hard-disk features remain options, and this print-only color laser has no scanner, copier or fax.
Confirm the paper before relying on duplex
The original guide supports ordinary duplex paper from 75 to 120 gsm. This is narrower than general one-sided media acceptance. Card stock, labels, transparencies and envelopes do not gain two-sided support simply because they appear in a general media table.
The automatic mechanism is positively established, but the manual explicitly says its paper-size table measurements apply to simplex printing. It supplies a minimum duplex size without a complete model-specific duplex-size list. Confirm the intended paper size and compatible driver before choosing the printer for a particular two-sided requirement.
Letter, Legal and A4 ordinary one-sided printing are established in the drawer and multipurpose feeder. Set the guides, panel size/type and computer settings to the actual load. Check a representative document and any preprinted stock for orientation before a larger run.
Keep included capacity separate from expansion
The supplied input combines a 250-sheet drawer and 100-sheet multipurpose feeder at the 75-gsm or 20-pound paper basis. It is not one large enclosed drawer. A feeder used for another stock replaces its ordinary-paper load, so select its source and type deliberately.
Suitable envelopes follow a separate one-sided multipurpose-feed routine, with the specified flap-up orientation and appropriate Envelope size/type. The stated capacity is ten envelopes, distinct from ordinary-sheet capacity. The 250-sheet output bin is another separate limit that may need attention during a longer job.
A separately installed 550-sheet drawer raises maximum input to 900. Update the printing software to recognize actual hardware, and use matching stock and type settings when linking ordinary trays. Do not count an absent drawer or assume that a photographed expanded arrangement is the supplied printer.
Release confidential output at the keypad
Compatible Windows Print and Hold or Macintosh Job Routing software can submit a confidential job with a user name and four-digit PIN. Choose the job from Held Jobs and enter the PIN locally to release it. The four-line grayscale display supplies status and menu guidance; its appearance is separate from color printing capability.
The routine stores jobs in memory and may delete them if more memory is needed. Whole-printer lockout and disk encryption require an installed, working optional hard disk. Confirm installed storage separately when disk-based controls are essential. The exact dn lists 256 MB standard memory and a 625-MHz processor, so check the actual configuration and application files rather than borrowing the n model's values.
USB Type-B connects a computer, while 10/100 Ethernet provides wired sharing. Verify network status and the correct queue. The front USB Direct host port has its own supported file and device restrictions. Historical compatibility lists do not establish current software, AirPrint or Mopria support.
Check the full supply system and workload
The exact US supplied Return Program starter toner declares 6,000 black and composite CMY pages. Replacement declarations include 4,000 or 8,000 black and 3,000, 5,000 or 7,000 CMY under ISO/IEC 19798 on the maker's continuous-print basis. Confirm exact cartridge identity, region and program conditions.
Separate photoconductors, the waste toner box, transfer belt and fuser also need inspection, including the correct fuser voltage. The 100,000-page maximum monthly duty figure does not replace the recommended 4,700-page ceiling. Lexmark marks this 58.75-pound model discontinued. Check its electrical label, cord, software and condition, with working clearance. A documented wireless or multifunction alternative is useful when either capability would simplify the daily routine.

Paper, software and setup details
Print-rate conditions
Maker maximum 24 black or 22 color one-sided Letter pages per minute. A4 and automatic-duplex rates are unestablished. First-page times and color-quality figures are separate measures.
Paper handling
Included 250-sheet drawer plus 100-sheet multipurpose feeder total 350 ordinary sheets at 75 gsm/20 lb. Letter, Legal and A4 are established for one-sided printing. Automatic duplex supports suitable ordinary paper at 75–120 gsm, but an exact duplex-size list is unestablished. Maximum 900 requires the optional 550-sheet drawer. Envelopes use a separate one-sided MP job and replace its ordinary-paper load.
Scanning arrangement
Print-only color laser hardware has no scanner glass, document-capture feeder, copying or fax. The four-line control display is grayscale; printing color does not supply scanning hardware.
Computer and mobile connections
Included USB Type-B and 10/100 Ethernet computer routes; front USB Direct supports documented flash-drive output. Parallel, serial, wireless and gigabit options require separate hardware. A host socket does not replace the computer interface.
Supplies and declared yields
Exact US supplied Return Program starter toner declares 6,000 black/composite CMY pages. Replacement declarations are 4,000 or 8,000 black and 3,000/5,000/7,000 CMY under ISO/IEC 19798 on the continuous-print basis. Match exact cartridge and program conditions; separate photoconductors, waste box, transfer belt and fuser need inspection.
Software and support
Exact numeric keypad and the guide’s compatible Windows Print and Hold/Mac Job Routing establish four-digit confidential PIN release from memory. Memory pressure can delete held jobs. Whole-printer lockout and disk encryption require optional working hard-disk hardware. Current OS and mobile compatibility are unestablished.
Electrical edition and setup
Inspect actual electrical label, proper cord, consumables and physical condition; nominal mains input is unestablished. Body is 19 inches high, 17.3 wide and 20.2 deep, weighing 58.75 lb before additional hardware. Exact dn includes 256 MB standard memory; optional drawer/storage must be installed and recognized by software.
