The Productivity Checklist

If you've got all these, then you've got a Lexmark!

Color science at work for you

For Lexmark, great color is more than a marketing promise it's a serious investment. Our development team is dedicated to delivering breakthrough color technology that truly enhances the value of your print communications. Lexmark's advanced color laser toner formula, combined with new temperature- and humidity-sensing technology, ensures excellent color reproduction and consistent quality from first page to last, across various media types and work environments.

Multitalented copying

Benefit from a rich range of advanced copy functions to boost your productivity, such as Priority Copy to interrupt long print runs temporarily; ID Card Copy to copy both sides of a card on to a single sheet; and Sample Copy (hard disk required) which lets you stop and take a good look at the first copy before releasing the rest of the job a great way to save time and reduce paper and toner waste.

Efficient traffic shaping

When you email a large file from your Lexmark X730 Series MFP, it won't cause a traffic jam on your network. That's because traffic-shaping technology can partition your network traffic and designate lower bandwidth for outbound flows. This is especially useful for busy networks and externally hosted Web servers.

Personalized user settings

A real efficiency booster, Lexmark's innovative MyMFP feature lets users save and retrieve their personal settings on a simple flash drive, including their local address book, personal fax numbers, individual copy settings, and even their own touch-screen configuration. They simply walk up to the MFP, slide in their flash drive and the MFP literally transforms into their own personal device. A warm welcome each time they use it!

Effortless manageability

Take a load off your IT department. These devices are network-ready and very easy to set up. If you have multiple Lexmark devices installed, the Lexmark Universal Driver offers even easier deployment. Once up and running, on-screen custom messaging makes life simpler too by providing users with crystal-clear information, like 'Toner Low, Call Placed." What's more, Lexmark MarkVision Professional software provides simplified remote management and automated tools to keep your workday flowing!

(See Lexmark Statement of Limited Warranty for full details)
