SC361-00
C
TD sensor output error: Upper Limit
TD sensor output voltage (Vt), measured during each copy cycle, is
detected higher than 4V for 10 prints.
-
 TD sensor defective
 TD sensor harness disconnected
 TD sensor connector disconnected or defective
 IOB defective
 Toner bottle motor defective
Note: When the TD sensor is defective, the toner supply is
controlled using pixel count and the ID sensor.
SC362-00
C
TD sensor output error: Lower limit
TD sensor output voltage (Vt), measured during each copy cycle,
is detected 10 times lower than 0.5V.
-
 TD sensor defective
 TD sensor harness disconnected
 TD sensor connector disconnected or defective
 IOB defective
 Toner bottle motor defective
Note: When the TD sensor is defective, the toner supply is
controlled using pixel count and the ID sensor.
