CAUTION: Read the following before handling electronic parts.

Handling ESD-Sensitive Parts

Many electronic products use parts that are known to be sensitive to electrostatic discharge (ESD). To prevent damage to ESD-sensitive parts, follow the instructions below in addition to all the usual precautions, such as turning off power before removing logic boards:

•Keep the ESD-sensitive part in its original shipping container (a special “ESD bag”) until you are ready to install the part into the machine.

•Make the least-possible movements with your body to prevent an increase of static electricity from clothing fibers, carpets, and furniture.

•Put the ESD wrist strap on your wrist. Connect the wrist band to the system ground point. This discharges any static electricity in your body to the machine.

•Hold the ESD-sensitive part by its edge connector shroud (cover); do not touch its pins. If you are removing a pluggable module, use the correct tool.

•Do not place the ESD-sensitive part on the machine cover or on a metal table; if you need to put down the ESD-sensitive part for any reason, first put it into its special bag.

•Machine covers and metal tables are electrical grounds. They increase the risk of damage because they make a discharge path from your body through the ESD-sensitive part. (Large metal objects can be discharge paths without being grounded.)

•Prevent ESD-sensitive parts from being accidentally touched by other personnel. Install machine covers when you are not work- ing on the machine, and do not put unprotected ESD-sensitive parts on a table.

•If possible, keep all ESD-sensitive parts in a grounded metal cabinet (case).

•Be extra careful in working with ESD-sensitive parts when cold- weather heating is used because low humidity increases static electricity.

The E310 is equipped with a Fast Ethernet and USB connectivity option, facilitating seamless integration into existing networks or directly to a single computer. With a print speed of up to 30 pages per minute (ppm) and a first page out time as fast as 6.5 seconds, users can expect quick document handling. The E310 supports a maximum print resolution of 1200 x 1200 dpi, ensuring sharp text and crisp graphics on printed materials.

One of the standout features of the E310 is its energy efficiency, designed to consume less power during operation, which can lead to significant cost savings over time. Additionally, this printer supports duplex printing, allowing for automatic double-sided printing, which not only enhances productivity but also helps to reduce paper costs. With a monthly duty cycle of up to 30,000 pages, the E310 is well-suited for medium-volume printing tasks.

On the other hand, the Lexmark E4044-XXX is designed for more demanding office environments needing higher output and advanced features. This monochrome printer also emphasizes speed and efficiency, with print rates reaching up to 40 ppm and a first-page print time of about 6 seconds. The E4044-XXX enhances productivity further with its duplex printing capabilities, and it can accommodate larger paper formats with options for various media types.

With a maximum print resolution of 1200 x 1200 dpi, the E4044-XXX provides even more precise text and graphics compared to its E310 counterpart. An impressive monthly duty cycle of 75,000 pages makes this printer suitable for high-volume printing needs. The model also supports fleet management capabilities, allowing businesses to manage multiple devices effectively through Lexmark's software solutions.

Both models feature innovative technologies like Lexmark’s Unison toner, which is engineered to deliver consistent quality and reduce wear on the printer. Coupled with easy-to-replace cartridges, this ensures that users maintain optimal print quality over time without unnecessary downtime.

In summary, the Lexmark E310 and E4044-XXX offer excellent reliability, efficient performance, and high-quality printing for various business needs, making them valuable assets for any office.
