STEP 1: In the paper feeding mode
If the equipment receives data, the control electronics activates the solenoid and rotates the
motor counterclockwise to drive the paper feed roller (and paper ejection roller). This pulls in
a sheet of paper and feeds it until its leading edge reaches the point just before the printing
position.
STEP 2: In the recording (platen drive & ribbon take-up) mode
The control electronics deactivates the solenoid and rotates the motor clockwise to drive the
platen gear and the ribbon take-up gear as well as the paper ejection roller. This feeds the
paper up to the printing position where the thermal recording head prints, as well as feeding
the thermal ink ribbon.
STEP 3: In the paper ejecting mode
The same operation as for STEP 1 takes place so as to eject the paper.
