HCPP Motor
HCPP stands for “Host-computer Control Paper Path”. The HCPP Motor is a 4 wire stepper motor that is used for
switching between the two paper paths (front and rear). Previous DFX family printers utilized the Ribbon Drive
Motor to accomplish paper path switching. The HCPP Motor, located on the left side frame, drives a series of gears,
moving the HCPP Slide Cam, which changes the paper path. The PPSS Sensor detects the position of the HCPP
Slide Cam.
