Calibration procedure1. Select the horizontal resolution to be calibrated from the printing mode list.2. Click “Print” in the horizontal test interface. The printer will print the horizontal calibration test images on media. Figure 3.23 Horizontal calibration test chart (partial)3. During calibration, select the calibration value aligned and add the value in the editing box behind the printhead number with this calibration value to obtain the new calibration value. Then enter the new calibration value into the editing box behind the printhead number. In the calibration diagram, the black lines in the center are the reference line. Colored line boxes above the black lines are forward calibration values of the printhead. The colored line boxes below the reference line are backward calibration values of the printhead. K0 printhead has only backward calibration values. Please pay attention to the position of the calibration value in the calibration value interface. Forward calibration values are not necessarily identical with corresponding backward calibration values. 4. Click “Effect” to print the step calibration effect images. Observe color lumps in the images and their junctions with the black lumps in the center. In the effect images, color lumps above the black color lumps correspond to the forward calibration effects and color lumps below the black color lumps correspond to backward horizontal calibration effects. If a color lump is at left side by comparing with the black color lump, reduce the calibration value based on the original calibration valve and increase the calibration value based on the original calibration value if the color lump is at right side. Note: it is better to keep the increased and reduced values within one to two pixels. Print the effect images after correction until all color lumps are completely aligned with the black color lump. High magnifiers can be used to observe the effect images. Figure 3.24 Horizontal calibration effect images5. Click “Check” to print the horizontal calibration check image. If all printed line segments are in the same straight line without any deviation, it indicates that the horizontal direction is precisely calibrated. If deviation occurs, calibrate the horizontal direction again.In the check images, the black line is the reference line. The colored lines above the black line correspond to the forward calibration effect and the colored lines below the black line correspond to the backward calibration effect. The colored lines in the center show the overprinting effect of the forward and backward directions. If a colored line is at left side by comparing with the black reference line, reduce the calibration value based on the original calibration valve and increase the calibration value based on the original calibration value if the colored line is at right side. Note: it is better to keep the increased and reduced values within one to two pixels. Print the check images after correction until all colored lines are completely aligned with the black reference line. High magnifiers can be used to observe the check images.
