2.2 Receiving Mechanism (Feeding paper and printing data)
The receiving mechanism consists of the recording paper cover ASSY, paper feed roller ASSY,
platen, thermal recording head, paper ejection roller, and sensors. (For details about the sensors,
refer to Section 2.4.)
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 ejection mode
The same operation as for STEP 1 takes place so as to eject the paper.
