Lexmark CS421dn Printer Review

Expert review of the Lexmark CS421dn printer

Our Verdict:
star
star-filled

The Lexmark CS421dn printer is a fully equipped digital A4 duplex colour laser copier and printer that combines intelligence and quality into an affordable, compact device. Get everything you require to power through your busy day at work. This also includes capabilities to support smart workflow, flexible paper handling, cutting-edge security and rapid output speeds. With its built-in hard disk, this Lexmark CS421dn printer provides the perfect platform that enhances standard productivity as well as security in any digital office.

Design

The Lexmark CS421dn printer measures 308 x 442 x 421 mm. It has a 1000 MHz Processor, a high capacity hard disk, and 512MB of RAM. It has three main paper handling trays that can accommodate 650 sheets and one multipurpose tray that can hold 100 sheets of paper. The printer has a maximum print resolution of 1200 x 1200 dpi. The scanner can accommodate a document up to 21.6 x 35.5 cm in size. The Lexmark CS421dn printer supports Windows and Mac operating systems and can be connected via USB or Ethernet network.

Advantages

This printer has personalized user settings such as the MyMFP feature, which allow users to save and access their personal copy or scan settings as well as an address book. It offers effortless IT manageability. Setting up the printer is easy, and in addition, supports a universal driver for simple deployment. It offers efficient services with embedded solutions for lowering costs, analysing usage data and expanding functionality. The printer streamlines tasks with ease, offering an ideal platform to boost security and productivity in a digital office.

Disadvantages

This printer can only produce documents of A4 size and therefore limits larger print outs of A3 size. The cost of repairing this printer is high due to expensive spare part items.
