5.2.8 ID SENSOR ERROR ANALYSIS (SP2-220)

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, SP2-220 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 SP2-220 (Vsg/Vsp/Vsdp/Vt/Vtref Dilay).
