OC Motor
OC stands for “Open/Close”. The OC Motor is a 4 wire stepper motor that opens and closes the Paper Bail. Previous
DFX family printers utilized a Paper Bail Solenoid to perform this function. The OC Motor drives the OC Slide
Cams.These OC Slide Cams, located on the left and right frames, open and close the Paper Bail. OC Sensor 1 and
OC Sensor 2 detect the position of the OC Slide Cams.
