Product Description¶

The MX-80 has a 9-wire print head that prints 96 ASCII characters with lowercase descenders and 64 graphics characters on a 9 by 9 dot matrix. The print head has an estimated life of over 500,000,000 characters, and it can be easily replaced. Print speed is 80 cps (characters per second) bidirectionally, and a long-life print ribbon is contained in an easily removable cartridge.

External features include a metal paper-guide rack, manual paper-advance knob, power switch, V.24 Interface, three control pushbuttons, and four green indicator LEDs (light-emitting diodes). In addition, the MX-80 has a tractor-feed paper mechanism and can use three-ply paper (original and two carbon copies). The On-Line pushbutton toggles the printer between on- and off-line modes. The FF (form feed) and LF (line feed) pushbuttons, functional only when the printer is off-line, advance the paper by one form (i.e.: page length) and one line, respectively. The distance that the paper advances may be changed under software control.
