Transfer voltage management
RTRBEN*: Enables the transfer voltage generation.
TRREAD: This voltage is proportional to the current on the transfer voltage. The value is between
0 and 3.3V. The minimum voltage is reached when Transfer = -800V and the maximum when
Transfer =-2200V.
TRPWM*: PWM signal used by the firmware to regulate the transfer voltage. The PWM frequency
is 16kHz. The duty cycle is between 0
%
and 100
%.
When RTRBEN* is ON(0) and TRPWM* is off(0%), the output voltage is reversed (Trans-
fer=+800) to discharge completely the drum and clean it.
To protect Digicolor, the signal RTRBEN* and TRPWM* should be properly buffered.
Toner management
PRBEN*: Enables the high voltage output to charge the drum.
DBEN*: enables the high voltage output to precharge the toner.
To protect the output of the Digicolor, these two outputs should be properly buffered.
