ID Sensor Error Analysis (SP2-221)
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, SP2-221 shows you some information
on the ID sensor. Check this information when the image quality is not very good.
