■ Tools:
1.5 mm Allen wrench; 2.5 mm flat-bladed screwdriver; 7 mm box wrench
CAUTION:
Turn off the printer and unplug it from its AC outlet.
Position the head higher than the printer console

gasket, one square 4-hole gasket)
□ Remove the ground braid screw from the body of the recovery solenoid valve.
□ Disconnect the solenoid valve rinsing hose.
□ To avoid damaging the recovery assembly, loosen the four screws in the corners of
the assembly by one full turn (do not loosen the central screw), detach the recovery
assembly, remove the four screws and gently remove the recovery assembly by pulling
it free in line with the head axis. Pay attention to the seals (O-rings around pins).
CAUTION:
The recovery detection pins and contacts are very fragile.
