2.
LEDs and Check Pins on the Finisher Controller PCB
Of the LEDs and check pins used in the finisher, those needed in the field are discussed.
Caution:
1. Some LEDs emit dim light even when OFF because of leakage current. This is a normal
condition and must be kept in mind.
2. Those check pins not shown in the table are for the factory only, and require special tools and
high accuracy. Do not touch them in the field.
