The model at a glance
The Samsung MultiXpress SL-K4250LX is a professional A3 monochrome laser multifunction printer, recommended for businesses, offices, professional practices, schools, public institutions, administrative departments and workgroups that need to print, copy and scan documents in A4 and A3 formats.
It is particularly suitable for invoices, contracts, quotations, accounting documents, administrative files, dossiers, manuals, tables, floor plans and digital archiving. Samsung offers a good balance of performance, durability and running costs, but without the particular specialisation of Kyocera in ultra-low-cost document printing or Xerox in colour graphics. As a monochrome device, it is not suitable for photographs or colour promotional materials.
Print speed: up to 25 pages per minute in A4 format and up to approximately 14 pages per minute in A3 format. This is the 25 ppm model in the Samsung MultiXpress K4 series.
Functions: printing, copying, colour scanning of originals, digital sending and document archiving. Fax is optional and can be added using a one- or two-line Samsung kit, so it must be verified for each individual configuration.
Duplex: integrated automatic duplex for printing, copying and scanning. It has a single-pass duplex document feeder that can scan both sides of a sheet in a single pass.
Print resolution: 600 × 600 dpi, with enhanced quality of up to 1,200 × 1,200 dpi at reduced speed. Samsung ReCP technology improves the definition of text, lines, monochrome graphics and professional documents.
Supported formats: A5, A4, A3, Letter, Legal, Ledger and custom sizes up to approximately 297 × 432 mm. The multipurpose tray can handle media from approximately 98 × 148 mm up to A3 format.
Supported paper weights: approximately 60 to 176 g/m², depending on the tray and media type. It handles plain paper, recycled paper, letterhead, preprinted paper, heavy paper, light cardstock, labels, envelopes and glossy paper compatible with laser printers. It is not suitable for very heavy 300-350 g/m² cardstock.
ADF: 100-sheet single-pass duplex automatic document feeder. Scanning speeds reach up to approximately 80 images per minute in simplex mode and up to 120 images per minute in black-and-white duplex mode; colour duplex scanning reaches up to approximately 100 images per minute.
Connectivity: Gigabit Ethernet 10/100/1000 network and USB 2.0. Wi-Fi, Wi-Fi Direct, Bluetooth and NFC are available via an optional module, so their presence must be verified on each individual machine.
