5.2.2 ID SENSOR ERROR ANALYSIS (SP 2221)
The image quality may become very bad when the ID sensor does not operate properly.
However, there is no such SC code that indicates ID-sensor malfunction; instead, SP 2221
shows you some information on the ID sensor. Check this information when the image
quality is not very good.
The table lists the information shown with SP 2221 (ID Sensor Error Analysis).
