9) Backflush a nozzle as follows:
Note: Backflush only one nozzle at a time.
a. Disconnect the outlet tubing from the valve that corresponds to the
nozzle you want to backflush. (See Figure 6B.) Direct the tubing into
a collection container.
b. Fill the syringe with solvent – porous or non-porous, as applicable.
c. Press the tubing against the nozzle to be backflushed, and depress
the plunger to force solvent through the nozzle.
d. Reconnect the outlet tubing to the valve.
e. Repeat the above steps for additional nozzles.
10) Reinstall the printhead assembly in the printhead case, and reconnect
the ground wire.
11) Reconnect the ink line, data lines, and power supply cables to the
printhead.
12) Plug in the printhead power supply and the controller.
13) Purge the printhead, then run a test print. (See “Purging a VJ
14) Was good quality print achieved?
• Yes, reinstall the printhead cover and resume normal operations.
• No, repeat the backflushing procedure. If good quality print is still
not attained go to double backflushing a nozzle.
