Replacing the 4 solenoid valve block
■ Tools:
1.5 mm Allen wrench.
CAUTION:
Turn off the printer and unplug it from its AC outlet.
Position the head higher than the printer console.
Residual ink may pour out, take appropriate precautions.
Perform this operation in a dust-free environment.
■ Disassembly:
□ Open the head rear cover
□ Unscrew the two screws holding the 4 solenoid valve block and remove the block.
Take care with seals (one rectangular 3-hole gasket, one square 4-hole gasket)
■ Reassembly:
□ Use solvent to clean the seal mating surface on the 4 solenoid valve block and the
contact board.
□ Replace the seals (2 flat gaskets) then replace the solenoid valve block.
■ Testing:
□ Restart the printer before closing the rear cover. Check that there are no leaks.
CAUTION:
The solenoid valve block must be replaced if there are any ink leaks
(risks of short-circuits on the integrated control ribbon cable).
□ Close the head rear cover.
□ A "stability check" is required.
