Printing on Labels

Use full label sheets only. Partial sheets (with areas exposed by missing labels) can cause labels to peel off during printing, resulting in a paper jam. Partial sheets can also contaminate your printer and cartridge with adhesive and can void the printer and cartridge service warranties.

Do not feed labels through the printer more than once. Doing so may result in adhesive contamination to the cartridge and other components.

Depending on your printer model and the number of labels you print, printing labels may require special printer maintenance. (Look under “printer maintenance” in the index of your User’s Guide or publications CD for specific information about maintaining your printer.)

If you print large quantities of labels or other glossy print media on a Lexmark C750 or C752, replace the fuser housing with a web oiler field upgrade kit (P/N 12G6307 for a 115 V printer, P/N 12G6308 for a 220 V printer).

Duplexing Paper Labels

Due to the special construction of labels, they are not typically duplexed. However, if certain design, construction, and usage guidelines are followed, you can print on both sides of the label sheet successfully.

When developing a paper label for duplexing, the converter should ensure that the label design protects against contamination or buildup. Contamination adversely affects paper feeding and causes paper jams in the printer.

We recommend labels used for duplexing have a non-adhesive border around the label area. In addition, make sure the release strength is sufficient to withstand temperatures of 225°C (437°F) and pressures to 25 psi. This is particularly important with a duplex application since the label is subjected to these extremes twice. Use label ties whenever possible. These small uncut areas (approximately 1.6 mm or 0.06 in.) help stabilize the label sheet and prevent tearing at perforations and die-cuts during printing. In addition, using ties helps prevent the labels from predispensing in the printer.

The slits and cuts in the labels expose the adhesives to the printer. For best results when duplexing labels, position the label sheet so that the slits and cuts are not aligned with the ribs in the duplex or redrive areas of the printer. (“Figure 1” and “Figure 2” on page 17 illustrate the rib locations for the Optra S and the Optra T, respectively.) This eliminates any contact points between the label adhesive and the printer, thereby preventing any adhesive contamination in the printer.

Other steps to ensure optimal printing include orienting the label in the tray so that the label end is fed into the printer first, and using long grain paper. Long grain paper tends to feed more reliably than short grain paper, which tends to curl more easily. As with any industry, product changes and improvements are constantly being developed. Therefore, if a converter develops a short grain sheet for use with duplexed labels, test the sheet to make sure it performs satisfactorily. In fact, we recommend testing any material with your application and printer before purchasing large quantities.

In order to use the duplex label application, you must install a special fuser wiper. The wax wiper that is used with the S1855, T612, T614, T520, and T522 is P/N 99A1082. The wax wiper that is used with the T620 and T622 is P/N 18A1467. The wax wiper that is used with the T630, T632 and T634 is

Laser Printers specifications

Lexmark laser printers are renowned for their high-quality printing solutions tailored for both personal and business environments. They leverage robust laser printing technology, which utilizes a laser beam to produce sharp text and clear images on paper. This method is not only efficient but also exceptionally fast, making it ideal for high-volume print jobs.

One of the standout features of Lexmark laser printers is their exceptional print resolution. Many models offer print resolutions of up to 1200 x 1200 dpi, allowing for sharp text and detailed graphics. This level of quality is particularly useful for businesses that require professional documents, presentations, and marketing materials. The clarity provided by Lexmark printers makes them suitable for various applications, from everyday office printing to specialized projects.

Lexmark also incorporates cutting-edge technology to enhance user experience and productivity. One such innovation is the Smart MFP (Multifunction Printer) technology, which combines printing, scanning, copying, and faxing capabilities into one device. This all-in-one functionality reduces the need for multiple machines, saving both space and maintenance costs. Additionally, many Lexmark models come equipped with intuitive touch-screen interfaces that simplify navigation and operation.

Another key characteristic is Lexmark's commitment to sustainability. Many of their printers are designed with energy-saving features, such as Sleep Mode and automatic duplex printing, which reduces paper usage. Lexmark also participates in recycling programs for toner cartridges, supporting environmentally responsible practices.

Moreover, Lexmark laser printers are well-known for their reliability and durability. Built with high-quality components, these printers are engineered to handle demanding workloads, maintaining peak performance over time. Businesses can rely on Lexmark printers for consistent output, which ultimately boosts overall operational efficiency.

Connectivity is another important aspect of Lexmark laser printers. With options for USB, Ethernet, and wireless connectivity, users have the flexibility to print from various devices, including computers, smartphones, and tablets. Furthermore, many models support mobile printing solutions, enabling users to print directly from their mobile devices via apps and services like Apple AirPrint and Google Cloud Print.

In summary, Lexmark laser printers are an excellent investment for those seeking high-quality, reliable printing solutions. With features like advanced print resolution, multifunction capabilities, sustainability initiatives, and robust connectivity options, Lexmark continues to be a leader in the laser printing industry, catering to diverse printing needs while maintaining efficiency and performance.
