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.
