4.2.3 Transmission of Ribbon Take-up Device
When capstan roller takes the paper, the ADF motor will release the paper lifter
and start to rotate gears and the ribbon. After locating the ribbon to the initial
position of each frame, the printing will begin.
4.2.4 Position of Platen, Pinch and Capstan
a) When the printer is in normal print status, thermal print head (TPH)
will contact Platen Roller tightly. Besides, Pinch Roller will contact
capstan roller tightly.
b) TPH will not contact platen roller under the process of the paper load
and ribbon search.
c) For preventing deforming pinch roller, on the standby status, capstan
roller and pinch roller have to be separated. For this supporse, the
printer built a series of gears and cams to decide the position of Pinch
Roller and Platen Roller.
