Fitting The
Squeegee
Printhead
Mechanism
The following procedure details how to fit the squeegee printhead mechanism
to the machine:
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 car-
riage 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

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 to 4kgs is monitored on the meter.
Tighten the three screws whilst the motor is under tension.
Front Squeegee
Drive Belt
To replace a broken front squeegee drive belt carry out the following
procedure:
1. To replace the front squeegee drive belt (left hand stepper motor), the
printhead mechanism must be removed from the print carriage.
