Signal Wire Name
Reference
TR-D/A ON(L) 5VDC
This is the output signal for both sides of the TR.
TR-A/D ON(L) 5.1VDC
This signal converts the TR output current that flows to the TR into a
voltage.
TR(–)
This signal controls the DC voltage sent from the HVPS to the BTR.
DB ON(L) 24VDC
This is the DB output signal. (It outputs both DC and AC components.)
CR-DC
This is the DC signal from the HVPS to the CR.
CR-AC
This is the AC signal from the HVPS to the CR.
TR
This signal is the output from the HVPS to the BTR.
* TR(–) is output during the transfer process and TR(+) is output while
cleaning of the BTR is taking place.
DB
This signal is the output from the HVPS to the magnetic roller. (Devel-
oping Bias)
CR
This signal is the output from the HVPS to the CR.
FAN ON(L) 5VDC
This signal controls the ON/OFF position of the fan according to the
remote signal.
The fan is turned ON when the signal is low.
