7.1.2 Major Components
T-7-1
LED array (64 LEDs)
on/off control
DC constant current control: switched over 3 settings in service mode
DC constant voltage control: determined by potential control
AC constant voltage control: switched over (frequencies) in service
mode
DC constant voltage control: determined by potential control
DC constant voltage control: on/off control only (+1000 V)
AC constant current control: fuzzy control by environment sensor
DC constant voltage control: on/off control only
DC constant voltage control: switched over according to temperature/
humidity
(high-humidity environment +200 V, low/normal environment +600 V)
DC constant current control: fuzzy control by environment sensor
DC constant current control: fuzzy control by environment sensor and
toner deposit
AC constant voltage control
