Side Registration Adjustment of the Cassette When the side registration of the cassette is not aligned, you need to make this adjustment. The side adjustment registration levers (see figure 4-3-3) in the upper and lower cassettes are adjusted in the factory. Therefore, there is no need to make any adjustments when installing the machine. However, in the event that either the upper or lower cassette needs replacing in the field, re-adjustment of the margins on left side is necessary. This procedure is outlined below. 1) Load 20 - 30 sheets of paper into the cassette. Then, using the printer driver tester, print several pages of all-black or horizontal line test prints. 2) Measure the distance (a) between the left edge of the page to the edge of the printed pattern (see figure 4-3-3). Measure several test prints to find the average distance. 3) Move the side registration adjustment lever so that the distance measured in step 2) is 3.0mm. (one notch alters length (a) by 0.5mm) For example, if the average length of step 2) is 4.0mm, by moving the lever 2 steps clockwise the necessary adjustment of 1.0mm can be made. 4) Make several more test prints. Make sure that the margin on left side is 3.0mm by repeating 4 - 15
