The Lexmark T640dtn is a high-speed monochrome laser printer that is suitable for workgroups with medium-to-high-volume printing demands. This is one of several models in the T640 series of printers, which primarily vary in terms of installed memory size and/or the capacity of the standard paper input tray. It will print on a wide range of media, including plain paper, card stock, labels and envelopes. In addition to standard toner cartridges, you can use high capacity cartridges to both save money and increase your productivity. Duplex capability is built in to allow you to use less paper for print runs.
Design
The printer weighs 25.23 kg and measures 535 x 425 x 637 mm. The capacity of the standard paper input tray is 850 sheets, and optional additional input trays can increase the capacity to 3,850 sheets. To facilitate the workflow within your office workgroup, an optional 5-bin mailbox is available in addition to a number of other finishing options. The printer features USB and ethernet network connection capabilities, and it is equipped with a 400 MHz processor and 64MB of RAM. The printer’s maximum monthly duty cycle is 200,000 pages, although Lexmark recommends keeping monthly printing volumes between 3,000 and 14,000 pages. The printer does not have Wi-Fi connection capabilities, but a wireless print server is available as an add-on option.
Advantages
The printer’s user-friendly control panel makes it easy to understand the unit’s printing and maintenance functions. With a time to print the first page of less than 6 seconds, this printer features a print speed of up to 33 ppm. Its print resolution is 1200x1200 dpi.
Disadvantages
The printer does not have colour printing, copying, faxing or scanning capabilities, which would require you to purchase an additional printer if you need those functions. Some reviews faulted this printer for the quality of graphics in printed documents.
