PRINT HEAD STEPPER DRIVE
If your Sharp SX

Bagger is equipped with a
printer, there will be an additional Stepper Drive to
control the Print Head. This drive controls the motor
that drops the print head onto the platen roller.
1. Check that the Stepper Drive is receiving
power by looking for the RED Status LED
(Figure 3-139).
2. Visually inspect all electrical components
looking for burn marks or deformed casings.
3. Make sure all wires are securely tightened in
their screw terminals.
There are no adjustments necessary on the Print
Head Stepper Drive.
1. Remove the two rear screws and the two front
screws from the Motor Cover (Figure 3-140).
2. Remove the Motor Cover and set aside.
