Printing method
Determine if the negative pressure value is set appropriately by checking the print head nozzle surfaces.
The negative pressure value is appropriate if flushed ink droplets are kept on the nozzle surfaces.
If the negative pressure value of the print head nozzle is too high, ink droplets on the nozzle surfaces are sucked
into the nozzles. If this is the case, lower the negative pressure value of the print head nozzle.

Clean the Gl print head nozzle surface using new cleaning sticks.
IMPORTANT
• Use dry non-woven fabric without using cleaning liquids.
• Never rub the nozzle surfaces hard.
After cleaning, determine if the negative pressure value is set appropriately by checking the print head nozzle
surfaces.
If the nozzle surfaces maintain conditions immediately after cleaning, the negative pressure value is
appropriate.
If the negative pressure value of the print head nozzle is too low, ink seeps from the nozzle surfaces. If this is the
case, increase the negative pressure value of the print head nozzle.
