9. To remove and replace the drive belt gear and flange assembly, simply push the gear flange away from the
gear shaft axle allowing the flange to unsnap and lift off (see Figure 3-15). To remove the gear, pull it straight
out from the chassis. To replace the belt gear and flange, follow this procedure in reverse order.
10. To replace the carriage assembly or drive belt, reverse the preceding process being very careful not to damage
the flex cable when inserting the cable through the chassis assembly. Also, use care when installing the
encoder strip, drive belt, and flex cable, as they must be installed properly to avoid rubbing against any other
components. If the drive belt, encoder strip, or flex cable rub against any components in the operation of the
print bar, premature failures will occur.
