Fitting Drip Tray 1. Slide the slot in the drip tray onto the bearing on the drip tray guide shaft.
2. Secure the drip tray to the actuator piston using the securing screw.
3. Open the speed control valves on the drip tray actuator.
Fitting Squeegee 1. Carefully position the rear of the printhead mechanism (spring beam
assembly) into the print carriage so that both printhead mechanism dowels
locate into the print carriage locating holes. Secure the unit to the print
carriage by means of the four captive screws, ensuring the pneumatic pipe
is not trapped.

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.

5. Remove the drive belt cover plate from the squeegee printhead mechanism
and remove the broken drive belt.
Rear Squeegee
Drive Belt
1. The rear squeegee drive belt (right hand stepper motor) can be replaced
without having to remove the printhead mechanism from the print carriage.
2. Slacken off the three screws securing the right hand motor to the motor
support plate.
3. Fit the new belt in position.
4. 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.
5. 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
1. To replace the front squeegee drive belt (left hand stepper motor), the
printhead mechanism must be removed from the print carriage.
