4.3.4.2 Adjustment Procedures
Because the adjustment mode is incorporated into the unit, the following adjustment procedure requires no
special equipment. All that is required is paper. The adjustment procedure is outlined in Figure 4-42. Note
that the adjustment must be carried out twice - once for Draft mode (120 dpi) and once for LQ mode (360 dpi).
