Resolution Resolution check points Actions and Questions Yes No Observe the three resolution check points on several Test Prints. Check the resolution of the images in each of the areas: Arrow 1 The two pixel vertical, horizontal and diagonal lines should be clear and continuous. The diagonal lines might appear to be narrower than the others. Arrow 2 The text paragraphs should be roughly equal in density. Arrow 3 The half-tone patches adjacent to the solid blocks in the corners should be uniform in appearance. Are the three checks points (arrows 1, 2, & 3) within specification? The printed test patterns meet the Resolution specification. Go to Registration (Side-to-Side) on page 3-47. Go to Resolution on page 3-72. 3-46 Phaser 4400 Laser Printer Service Manual
