Product Description

The Lexmark CS943de colour printer is designed for security, usability and reliability for large workgroups at speeds of up to 55 pages per minute*.

Flexible input and output for all of your printing needs

If you need to print or scan media larger than A4, this large-format model supports paper sizes slightly larger than SRA3+ (up to 329 x 483 mm) and standard input capacity of 1,140 pages. Optional additional trays expand the paper input capacity to up to 5,140 pages. There are several finishing options: staple finisher, staple hole-punch finisher, booklet finisher or Lexmark’s first trifold/Z-fold finisher.

Secure by design

Lexmark security features help to keep your information safe - in the document, on the device, over the network and at all points in between. Always improving security, we now include a standard Trusted Platform Module**, which delivers authentication, system integrity checks, and cryptographic capabilities to create a unique digital system fingerprint.

Enhance professional image with brilliant colour for large-format printing

Enjoy vibrant colour with standard advanced features like PANTONE® calibration and Lexmark Named Colour Replacement for consistent branding and professional appearance.

Put the Internet of Things (IoT) to work for you

Our sophisticated, IoT-enabled printers are loaded with sensors that continuously monitor hundreds of data points that provide added benefits, like predictive service and automatic supplies replenishment, when they are connected to Lexmark Cloud Services.

Always focused on sustainability

Automatic two-sided printing is standard, along with built-in energy-saving modes that help to support ratings of EPEAT® Silver and ENERGY STAR® certified. The award-winning Lexmark Cartridge Collection Programme (LCCP) and Lexmark Equipment Collection Programme (LECP) minimise waste and support recycling (availability varies by country).

**The Trusted Platform Module (TPM) is not available in some countries.
