8.1 Principle of Operation

The KX-P1150 has three Micro switches. The home position switch sets a reference for the carriage and is

necessary for aligning the first print position. The Friction/Tractor switch detects the selected method of
paperfeed (Friction or Tractor).
The paper out switch detects paper end and prevents printing when the printer is out of paper.

The printer has three drive circuits: carriage spacing motor, paper feed motor and printhead.
The control panel is composed of switches and LEDs that indicate the various states of the printer.
