Tacho and Sensor System
1.
Carefully withdraw the Tacho Wheel plastic cover from the side of the Printer. There
is a spring behind so ensure it is removed slowly (omitted for clarity).
2.
The Tacho wheel can now be removed but it will also have to be tilted away from the
Tacho Sensor.
3.
Tacho Sensor can be removed by unclipping the outer plastic housing and sliding
the Sensor outwards.
Refitting is the reverse procedure but ensure the Tacho wheel passes through the
Tacho Sensor before fitting the plastic cover.
Print Head Cam System
1.
Cam Position Sensor can be removed by unclipping the
outer plastic housing and sliding the Sensor outwards
(ensure the Pulley is rotated to the correct position).
Refitting is the reverse procedure.
2.
Drive Belt can be removed by sliding it off the outside of the
Cam Shaft Pulley.
Refitting is the reverse procedure.
3.
Small Pulley can pulled from the DC Cam Motor shaft.
Refitting is the reverse procedure but a new Pulley is
essential unless glued into position.
SECTION 11.8
REMOVAL & REFITTING OF LEFT SIDE COMPONENTS
CAUTION
The Plastic Drive pulleys attached to any of the Motors are designed to be push-fit and used only once.
Magicard highly recommend new Pulleys are fitted if they are disturbed. Once pushed onto the motor
shaft, the plastic deforms to produce a tight fit.
