OPERATOR MANUAL

CLEANING the failing heads:

-Set the valves of the failing heads to the “S” position.

-Set the Solution valve to “S”.

-Push the “Solution-Purge” button on the back of the carriage. (Keep pushing until you see a CLEAR “Solution-Curtain” under the heads, then stop pushing)

-Leave the heads in this condition for at least 5 minutes.

-Set the valves back to “I”.

-Set the Neg. Pressure to “0”, leave the system for 1 minute (Ink will now start dripping out the heads)

-Restore the Neg. Pressure back to “-.034”

-Clean the heads with a fiber-free cloth.

-Check on “weeping” (**)

Solution-Curtain

When purging with “Cleaning-Solution”, always work the in three steps.

To clean all 8 heads, first purge the 4 right heads (Lc, Lm, W1, W2), close them,

and in the second stage, purge the remaining 4 left heads (K, C, M, Y). Finally, open the 4 right heads again, and purge all 8 heads together now. By doing so, you’ll have the most optimal cleaning pressure.
