Paper guidelines

Selecting the correct paper or specialty media reduces printing problems. For the best print quality, try a sample of the paper or specialty media before buying large quantities.

Paper characteristics

The following paper characteristics affect print quality and reliability. Consider these characteristics when evaluating new paper stock.

Weight

The printer trays can automatically feed paper weights up to 90 g/m2 (24 lb bond) grain long paper. The multipurpose feeder can automatically feed paper weights up to 163 g/m2 (43 lb bond) grain long. Paper lighter than 60 g/m2

(16 lb) might not be stiff enough to feed properly, causing jams. For best performance, use 75 g/m2 (20 lb bond) grain long paper. For paper smaller than 182 x 257 mm (7.2 x 10.1 in.), we recommend 90 g/m2 (24 lb) or heavier paper.

Note: Duplex printing is supported only for 60–90 g/m2 (16–24 lb bond) paper.

Curl

Curl is the tendency for paper to curl at its edges. Excessive curl can cause paper feeding problems. Curl can occur after the paper passes through the printer, where it is exposed to high temperatures. Storing paper unwrapped in hot, humid, cold, or dry conditions, even in the trays, can contribute to paper curling prior to printing and can cause feeding problems.

Smoothness

Paper smoothness directly affects print quality. If paper is too rough, toner cannot fuse to it properly. If paper is too smooth, it can cause paper feeding or print quality issues. Always use paper between 100–300 Sheffield points; smoothness between 150–250 Sheffield points produces the best print quality.

Moisture content

The amount of moisture in paper affects both print quality and the ability of the printer to feed the paper correctly. Leave paper in its original wrapper until it is time to use it. This limits the exposure of paper to moisture changes that can degrade its performance.

Condition paper before printing by storing it in its original wrapper in the same environment as the printer for 24 to 48 hours before printing. Extend the time several days if the storage or transportation environment is very different from the printer environment. Thick paper may also require a longer conditioning period.

Grain direction

Grain refers to the alignment of the paper fibers in a sheet of paper. Grain is either grain long, running the length of the paper, or grain short, running the width of the paper.

For 60–90 g/m2 (16–24 lb bond) paper, grain long paper is recommended.

430, 420 specifications

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.
