Shipping Information

The shipping process is fully robotic and orders are normally pulled and shipped quickly in 7 different warehouses across the US and then dropped in sealed USPS, UPS and FedEx containers for pick-up on the next business day. High volume or backordered items may have additional shipping delays. Once pulled, orders cannot be stopped, however you can return orders for refund unopened if you have changed your mind. Tracking normally is sent / updated within 48 hours of pick-up. Delivery is normally 3-10 business days after leaving the warehouse, however carrier delays may occur. Shipping may take longer in rural areas, due to carrier delay, weather or acts of God. Weekends and Holidays do not count as business days and have no pickup, movement or delivery.

Covid 19 Update — We have seen slowdowns and backlogs in package pickup, sorting, scanning and delivery by UPS, Fedex and USPS caused by worker shortages and facilities disruption due to the Covid 19 Pandemic. Some UPS and USPS hubs are no longer scanning all packages, as a result some tracking will show nothing until delivery.

Full-spectrum security

Lexmark's comprehensive approach to product security is a design and engineering mandate across our entire product portfolio. Our security features help keep your information safe-in the document, on the device, over the network, and at all points in between.

Connectivity central

In addition to Ethernet and USB, built-in Wi-Fi makes it easy for mobile users to get output via the Lexmark Mobile Print app, as well as Mopria®, AirPrint and Google Cloud Print. And the Lexmark Mobile Assistant app simplifies wireless configuration.

Save paper, save energy

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

Versatility that fits

Measuring just 13.3 inches high x 16.2 inches wide x 14.4 inches deep (339 mm high x 411 mm wide x 366 mm deep), the business-class MX431adw fits almost anywhere. Its compact size and light weight make it easy to set up and easy to move.

Interact with ease

Take command of printing, copying, faxing, and automatic two-sided scanning with a 2.8-inch (7.2 cm) color touch screen. It not only supports convenient interaction with essential system functions and task information, but includes built-in cloud connectors to help you save scans to and retrieve files from popular cloud services Box, DropBox, Google Drive, and Microsoft OneDrive.

Print more, stop less

In addition to a first page as fast as 5.9 seconds and output up to 42 pages per minute, available Extra High Yield Unison™ toner provides up to 20,000 pages of output, while an optional paper tray increases total input capacity up to 900 sheets for more printing and less downtime. And with its steel frame and lifetime fuser, the MX431adw is built to last.
