Advo Focus Brain

The printer does not have display screen, which means you have to consult the manual when there is a problem. It has six LED's that will blink on a certain pattern that will tell you what is wrong with the device. These patterns can be anything from paper jams to toner cartridge problems. There are only two buttons on it.
