Detection of the Feeder configuration through the FEEDER CK signal
When no 500 Sheet Feeder is attached, 3.3 VDC is divided by the resistances R10K and
R4.7K on the Print Engine Controller PWB, and the voltage across the resistance R4.7K
appears on the FEEDER CK signal. When one or two 500 Sheet Feeders are added, the
resistance RF on the PWB Feeder of the added Feeder(s) is connected in parallel with the
resistance R10K of the Print Engine Controller PWB, and the voltage across the resis-
tance R10K changes according to the number of 500 Sheet Feeders added. Therefore,
the Feeder configuration can be detected from the voltage of the FEEDER CK signal.
