To replace the ProFlow drive belt the printhead mechanism must first be
removed from the print carriage, carry out the following procedure:
1. In Print Carriage Diagnostics, select Drive Carriage to Front Position.
Power down the machine, raise the machine covers.
2. Remove the ProFlow unit if fitted.
3. Disconnect all plugs from the printhead mechanism to the connector panel
on the print carriage.
4. Remove the printhead mechanism by unscrewing the four captive screws
securing the unit to the print carriage.
5. Placing the unit on a secure surface, slacken off the four screws securing
the stepper motor to the support plate, (figure below refers).
6. Remove the old drive belt. Fit new belt in position.
7. Using a cable tie wrap or similar, provide a loop around the top of the motor
body 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
