CAUTION:
Turn off the printer and unplug it from its AC outlet.
Residual ink may pour out, take appropriate precautions.

■ Disassembly:

resonator wires.
□ Unscrew the two screws holding the modulator assembly and remove it. Take care
with the seals (two O-rings).
■ Reassembly:
□ Clean the seal mating surface with additive, remove the old O-rings and fit two new
O-rings in their locations on the head.
□ Place the new modulator assembly in position then tighten the two mounting screws.
□ Reconnect the resonator power supply cord and reinstall the protective cover.
