3. Measure the distance between the developing roller and the doctor blade with a
thickness gauge as shown in Figure 3-3-64, and adjust the doctor blade until the
correct distances are obtained at the center and ends of the developing unit
housing; the 0.50 mm gauge should go into the gap and the 0.55 mm one should
not.
∗ The smaller the distance, the lighter the image; the larger the distance, the darker
the image.
