Intermec EasyCoder PC41—Service Manual
The motor assembly consists of a stepper motor and a thermistor mounted
on a bracket, which is attached to the inner, right side of the base frame
moulding. The motor pulley and two shafts protrude through holes in the
base frame moulding. Outside the moulding two gears are fitted on the
shafts. The gears form a train from the motor pulley to the gear of the platen
roller. The platen roller gear engages the ribbon takeup gear, when the print
frame is closed.
The stepper motor is connected to J2 and the thermistor to J4 on the main
board.
The motor assy mechanism comes as a complete unit including stepper
motor, bracket, thermistor, gears, washer, E-rings, and nuts.
