Note!
Before replacing any electrical parts such as SUx (Scanner Control Unit) or the CIS Unit, the parameter block should be erased and the
scanner calibrated. This will solve the problem in most cases, especially if the reported problem is about image quality or identifying the
calibration sheet. The Pressure Rollers and the Glass Plate should also be inspected for wear and tear.
