The X83 is the luxury version of the X73. Lexmark has embellished it with a liquid crystal screen and 8 MB of memory to speed up the device and make it easier to work in autonomous mode. But it is also far and away the cheapest in the test. Its cost per page is reasonable and its speed is medium though adequate, making it a very good starter device.
Lexmark has focused on the essentials, so there is no question of page feeders, faxes or card readers. The X83 prints, scans and photocopies, period. The control panel is thus completely devoid of embellishments - it is both very plain and very efficient.
