LED as the scanner light source

We’ve changed the light source for the scanners in our devices from conventional fluorescent lighting to LED. This delivers power savings and a low heat performance while increasing brightness intensity and scanning speed.

Media Detection

Intelligent media sensor automatically detects which paper is being printed on, resulting in fewer paper feeding problems, time savings and higher productivity. See video below.
