19.2 How to identify problematic part

• This chapter is divided into two parts: "Initial check items" and "Troubleshooting proce-

dure by a particular image quality problem."

• When an image quality problem occurs, first go through the "Initial check items" and, if

the cause is yet to be identified, go to "Troubleshooting procedure by a particular image

quality problem."
