ABSTRACT:
An abnormality of a key component of an electrostatic image-recording machine is detected using a surface potentiometer originally installed in the machine for use in controlling the charging voltage of the photoreceptor drum. The detectable components are: main charger, transfer charger, discharge lamp, and developing roller. They are judged abnormal if the voltage of the drum surface is out of a normal range when they are functioned before an actual recording process (or during warming-up of the machine).
