2. Connect the following connectors to the print carriage, left hand side:
• Rear Squeegee Motor
• Front Squeegee Motor
• Home Sensors
• Squeegee Pressure Amplifier
3. Fit the required configuration of squeegees to the printhead mechanism
squeegee mounts.
NOTE
Squeegee fitting information is detailed in the Replacement Procedures
section of this chapter.
4. Switch the mains isolator to ON and ensure that the machine recognizes the
squeegee module fit by displaying Squeegees Uninitialised during the
machine initialisation sequence.

and remove the broken drive belt.
NOTE
In the drive belt replacement procedures, described below, the tensioning of the
belt only applies where the squeegee stepper motors are identified by the green
label shown in figure 9-3. For all other squeegee types, follow the ‘Alternative
Drive Belt Replacement’ procedure.
Rear Squeegee
Drive Belt
The rear squeegee drive belt (right hand stepper motor) can be replaced without
having to remove the printhead mechanism from the print carriage.
1. Slacken off the three screws securing the right hand motor to the motor
support plate.
2. Fit the new belt in position.
3. Using a cable tie wrap or similar, provide a loop around the top of the body
of the motor enabling the motor to be pulled using a force meter. Ensure
that the force meter is pulled in the direction which the drive belt is fitted,
figure above refers.
4. Pull the force meter until a tension of 3-4kgs is monitored on the meter.
Tighten the three screws whilst the motor is under tension.

Front Squeegee
Drive Belt
To replace the front squeegee drive belt (left hand stepper motor), the printhead
mechanism must be removed from the print carriage.
1. Disconnect the following connectors from the print carriage, left hand side.
• Rear Squeegee Motor
• Front Squeegee Motor
• Home Sensors
• Squeegee Pressure Amplifier
2. Remove the printhead mechanism by unscrewing the four screws securing
the unit to the print carriage.
3. Placing the unit on a secure surface, slacken off the three screws securing
the left hand motor to the support plate.

4. Fit the new belt in position.
5. Using a cable tie wrap or similar, provide a loop around the top of the body
of the motor enabling the motor to be pulled using a force meter. Ensure
that the force meter is pulled in the direction which the drive belt is fitted,
Rear Squeegee Motor Tensioning figure example refers.
6. Pull the force meter until a tension of 3-4kgs is monitored on the meter.
Tighten the three screws whilst the motor is under tension.
7. On completion re-fit the printhead mechanism to the print carriage refit the
drive belt cover plate and re-connect all leads to the print carriage, left hand
side.
8. Refit the squeegees.
