Minimizingyourprinter'senvironmental impact

Lexmark is committed to environmental sustainability and is continually improving its printers to reduce their impact on the environment. We design with the environment in mind, engineer our packaging to reduce materials, and provide collection and recycling programs. For more information, see:

•The Notices chapter

•The Environmental Sustainability section of the Lexmark Web site at www.lexmark.com/environment

•The Lexmark recycling program at www.lexmark.com/recycle

By selecting certain printer settings or tasks, you may be able to reduce your printer's impact even further. This chapter outlines the settings and tasks that may yield a greater environmental benefit.

Saving paper and toner

Studies show that as much as 80% of the carbon footprint of a printer is related to paper usage. You can significantly reduce your carbon footprint by using recycled paper and the following printing suggestions, such as printing on both sides of the paper and printing multiple pages on one side of a single sheet of paper.

For information on how you can quickly save paper and energy using one printer setting, see “Using Eco-Mode” on page 36.

Using recycled paper and other office papers

As an environmentally conscientious company, Lexmark supports the use of recycled paper produced specifically for use in laser (electrophotographic) printers.

While no blanket statement can be made that all recycled paper will feed well, Lexmark consistently tests papers that represent recycled cut size copier papers available on the global market. This scientific testing is conducted with rigor and discipline. Many factors are taken into consideration both separately and as a whole, including the following:

•Amount of post-consumer waste (Lexmark tests up to 100% post-consumer waste content.)

•Temperature and humidity conditions (Testing chambers simulate climates from all over the world.)

•Moisture content (Business papers should have low moisture: 4–5%.)

•Bending resistance and proper stiffness means optimum feeding through the printer.

•Thickness (impacts how much can be loaded into a tray)

•Surface roughness (measured in Sheffield units, impacts print clarity and how well toner fuses to the paper)

•Surface friction (determines how easily sheets can be separated)

•Grain and formation (impacts curling, which also influences the mechanics of how the paper behaves as it moves through the printer)

•Brightness and texture (look and feel)

Recycled papers are better than ever; however, the amount of recycled content in a paper affects the degree of control over foreign matter. And while recycled papers are one good path to printing in an environmentally responsible manner, they are not perfect. The energy required to de-ink and deal with additives such as colorants and “glue” often generates more carbon emissions than does normal paper production. However, using recycled papers enables better resource management overall.

Lexmark concerns itself with the responsible use of paper in general based on life cycle assessments of its products. To gain a better understanding of the impact of printers on the environment, the company commissioned a number of

The Lexmark 420 and Lexmark 430 are part of Lexmark's line of efficient and robust printers crafted to meet the demands of both small businesses and larger work environments. These printers are designed with a focus on delivering high-quality output, reliability, and advanced features that streamline the printing process.

One of the standout features of the Lexmark 420 and 430 is their printing speed. The Lexmark 420 can achieve print speeds of up to 30 pages per minute (ppm) while the Lexmark 430 offers a slightly higher speed, reaching up to 35 ppm. This means that both models are well-suited for high-volume printing tasks, allowing users to print large documents quickly and efficiently.

In terms of print quality, both printers utilize advanced laser technology. They are capable of producing sharp text and vibrant graphics with a maximum resolution of 1200 x 1200 dpi. This level of detail makes these printers ideal for producing professional documents, including reports, presentations, and marketing materials.

Another key characteristic of the Lexmark 420 and 430 is their paper handling capabilities. Both models support a variety of media sizes and types, including letter, legal, and A4 sizes, as well as envelopes and labels. The standard input tray has a capacity of 250 sheets, and there is an option to add additional trays for increased capacity, making these printers versatile in handling different printing needs.

Connectivity options are another significant aspect of the Lexmark 420 and 430. These printers feature USB and Ethernet interfaces, allowing for easy integration into both wired and wireless networks. This connectivity facilitates convenient sharing among multiple users in an office environment, enhancing productivity and collaboration.

Security features are also well-implemented in both models. They come equipped with secure printing options to protect sensitive documents, ensuring that only authorized personnel can access printed materials.

Finally, user-friendly interfaces and intuitive control panels make the Lexmark 420 and 430 easy to operate, with options for setting preferences and monitoring printer status efficiently. With their combination of speed, quality, and versatile features, the Lexmark 420 and 430 are solid choices for any office looking to enhance productivity and maintain high printing standards.
