Lowering the Negative Pressure Value of the Print Heads

Adjust the negative pressure value to be suitable for your usage environment. Dot drop-out and dot displacement occur when the negative pressure value is too high. In these cases, set a lower value.

MEMO

Check that the print-head carriage has returned to the maintenance station. If the machine detects an intrusion into the movable range of the print-head carriage while the carriage is not in the maintenance station, the safety protection function is activated to stop the machine.Safety Protection Function

  6. Adjust the negative pressure of the print head for which dot drop-out or dot displacement is occurring.

    Adjust the negative pressure for the print heads K, C, Y, and M on Negative Pressure (colors) and for the print heads Gl and Wh on Negative Pressure (White).

    IMPORTANT
    • Make a note of the negative pressure values P - 1 and P - 2 before starting adjustment.
    • To adjust the negative pressure, adjust the values of both P - 1 and P - 2. Be sure to set a value for P - 2 that is larger than P - 1.
    • Change the value by 0.1 at a time during adjustment.
