What can great colour do for you?

A little colour can go a long way!

Studies consistently show that colour enhances communication both internally and externally. It improves readability, comprehension and brand recognition. And it simplifies buying decisions by helping customers cut through the clutter of competing messages.

Colour can bring added value to all areas of your business, from marketing and communication to real estate and finance. A 2007 InfoTrends study shows that invoices produced in colour improve payment response by almost 30%, and customers are more likely to pay the full amount!

So today the question is no longer, can you benefit from colour? The question is, how can you BEST benefit from colour? The Lexmark C730 Series delivers the answer.

Going far beyond quality, these high-powered partners offer you the tools and technology you need to save time, lower costs and print more responsibly for the environment – in colour!

The Productivity Checklist

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

Instant warm up

With Lexmark’s instant-warm-up fuser, your printer will be racing through documents in the time it takes many other printers to even wake up. In addition to getting your print jobs in your hands faster – just seconds from a cold start – you’ll also benefit from increased efficiency. So you save time, energy and money all at once!

Intelligent Job Waiting

One person’s setback should never mean a bottleneck for the whole workgroup! Say someone launches a print job that requires labels, but there are none loaded. Why lose precious uptime? Lexmark’s Job Waiting feature will simply hold that job aside while everyone else goes on working without interruption (hard disk required).

Colour science at work for you

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

Cutting-edge security

From network security to user-access restrictions, Lexmark offers you a wide range of features to help protect your valuable data and ensure the integrity of your network. In addition to IPSec, SNMPv3 and 802.11x network security, the Lexmark C730 Series offers an alphanumeric pad for easy PIN authentication, plus encryption and disk wiping to secure your optional hard disk.

Simplified management

Take a load off your IT department. These printers 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!

Cost saving and environmental features

Duplex models are Energy Star compliant.

Duplex printing, print and hold, multi-up and support of recycled paper help reduce paper consumption

Eco-Mode reduces power consumption and Quiet-Mode reduces noise emission

Lexmark Cartridge Collection Program helps reduce landfill.

Lexmark’s guarantee to you

Lexmark's 1-Year Onsite guarantee on the Lexmark C730 Series provides added peace of mind. Enhanced service offerings may be available by contacting your Lexmark representative or visiting www.lexmark.com.

Duty Cycle Notes "Recommended Monthly Page Volume" is a range of pages that helps customers evaluate Lexmark’s product offerings based on the average number of pages customers plan to print on the device each month. Lexmark recommends that the number of pages per month be within the stated range for optimum device performance, based on factors including: supplies replacement intervals, paper loading intervals, speed, and typical customer usage. 
"Maximum Monthly Duty Cycle" is defined as the maximum number of pages a device could deliver in a month using a multishift operation. This metric provides a comparison of robustness in relation to other Lexmark printers and MFPs. 
Specified Operating Environment Temperature: 16 to 32°C

Q. Why does my Standard Ethernet port become inactive when I install an optional Lexmark MarkNet internal print server?

A. Lexmark business products only support one active internal networking connection. Installing an optional Lexmark MarkNet N8100 Series internal print server permits the N8100 Series print server to become the active network connection while simultaneously disabling the Standard Ethernet port.


Q. What is the Lexmark Coverage Estimator?

A. The Lexmark Coverage Estimator uses an algorithm to count the picture elements (pixels) in the composite page to estimate the percent coverage for each color, cyan, magenta, yellow and black. When the Coverage Estimator has been turned ON from the printer's operator panel Utility Menu, the calculated estimate is printed on a separate page at the end of the job. This handy tool allows you to quickly and easily determine the amount of cyan, magenta, yellow and black toner used on a given page, even in complex photographs and images. Understanding the cost of the page is then just a matter of a few simple calculations. The communication of content in many black and white documents can be improved for a nominal increase in cost when color is added. Of course, the Coverage Estimator is only an estimate of the coverage on a given page. For each toner color that is used, the minimum percentage reported will be two percent and reported values may vary from one printer to another. The accuracy of the estimates may be affected by the fullness of the print cartridges, environmental conditions, media type, application, application settings, driver, driver settings, and the content of the page. Lexmark makes no claim as to the accuracy of the estimated percents.
