Ribbon Takeup Drive Train
Intermec EasyCoder PC4—Service Manual
The ribbon takeup assembly is driven by the stepper motor via a train of
gears. There is a spring-loaded arm with two connected gears under the
ribbon takeup. The rear gear engages the gear wheel of the ribbon takeup,
whereas the other gear engages the gear train in the base frame when the
print frame is in closed and locked position. This implies that the ribbon
takeup can be rotated freely in both directions when the print frame is in
open position, but only in one direction when it is closed.
There are no facilities for adjustments.
