How-To: Print Head Position Adjustment (SG400/800)

  • Updated

This will adjust the print head position settings. Perform this operation if printed lines are vertically misaligned or printed colours are blurred.

To check all adjustment values, print the test pattern applying "High Speed", "Standard", "High Quality",  settings.

If there are several lines in the test pattern, check the adjustment values for each line, and adjust the print head positions. If the adjustment value is set to "0", no adjustment is necessary. Adjust all lines so their adjustment values indicate "0"

    A test pattern to adjust print head positions is printed.

  6. To determine the adjustment value, select the square that is faintest (closest to white). Alternatively, select the square whose internal lines overlap to form a single color.mceclip8.png

    Combined two-color lines form squares, and depending on line overlapping, (white) spaces between the lines are painted and look darker. Sometimes the colors of the lines are identical.

    For this illustration, the adjustment value is "-2". Checking adjustment values for each item is required.

    If you cannot determine the adjustment value, select the square that is between the straightest lines.

    Each vertical line is made of an upper part and lower part. If the print head is not properly positioned, the vertical line will be displayed as two disconnected lines, so that the line looks misaligned.

    If you still cannot determine the adjustment value, locate the square that is between adjacent squares whose lines form symmetry. Adjacent squares can be one or two places either side (at positions ±1 or ±2).

    This illustration indicates an adjustment value that is set to "-1".mceclip10.png
