5050-001 12. When all the values are acceptable for all colors, exit diagnostics. Example of the Adjustment Here is a sample of the magenta radar image. Looking down the left side for both X and Y you can see the X value is close to correct. It may be a little to the right. The Y value for magenta is incorrect. The magenta radar image is too far above the black. In the case of Y, increase the value for Y to move the magenta image down the page. This may not seem intuitive, but increasing the value increases the timing delay, thus moving the image down the page. The images may be off by different amounts. Make the best overall judgment using all the radar images on the left side.

When the Y value is correctly adjusted the magenta radar image should look like the following example. The Theta adjustment is done in the same manner as the Y except theta values are taken from the right side of the test pages.
