Product Description

Lexmark X644e TONER - 32,000 Pages

This Toner Cartridge prints 32000 pages with an average 5% page coverage. The amount of pages can vary depending upon the amount of ink printed onto each page. (5% page coverage is a standard Lexmark specification)

This product comes with a 6 month Warranty against any defects (including free replacement). We stand behind our products 100%, as these are not manufactured by Lexmark.

Why toner? Why not call it ink? Regular ink dries quickly, which is why cartridges for inkjet printers do not last long. Laser Printers use toner, which is ink in the form of powder. A sealed toner cartridge can be stored for 2+ years prior to usage.

Overview:

The Lexmark X644e provides you with professional quality documents. Images and text documents print with a resolution of 2400 dpi and 600x600 dpi. This unit is perfect for offices with heavy printing needs. Toner cartridges yield 32,000 pages. There is also a 2,000 sheet paper tray that is available for the Lexmark X644e.

Pros:

The Lexmark X644e offers printing, scanning, faxing, and copying. There is an 8 inch touch screen control panel that is easy to see and use. This unit produces the first copy in just seven seconds. The copier can reduce originals to 25% enlarge them to a maximum size of 400%. The scanner offers a resolution of 600x600 dpi and has a maximum scan area of 8.5x14 inches.

Toner cartridges for the unit are easy to remove and replace. High yield toner cartridges for the Lexmark X644e produce 21,000 pages. Even higher yield cartridges are available that offer yields of 32,000 pages.

This unit offers outstanding quality output. Text documents are sharp and easily readable at 4 point fonts. This unit also offers a duplexer that will reduce the amount of paper you use. The machine supports Mac and Windows operating systems.

Cons:

The first drawback to the Lexmark X644e is that while paper capacity can be increased, the standard version is rather limited when it comes to paper handling capabilities. Another shortcoming of this unit is that it lacks finishing features such as automatic sorting.
