The functions and methods used in the machine's image formation system are as follows:
Photosensitive drum
Amorphous silicon (80-mm dia.) Cleaning method: blade
Developing assembly
Developing cylinder (24.5-mm dia.)
Developing method: dry, 1-component, toner projection
Toner: magnetic, negative
Pre-exposure
Array of 63 LEDs
Turning on/off the Pre-exposure LED Array.
Potential sensor
Potential Control
[1] Setting the primary current
[2] Setting the laser output
[3] Setting the developing bias (DC)
Wire auto cleaning
[1] Primary charging wire
[2] Pre-transfer charging wire
[3] Transfer charging wire
[4] Separation charging wire
Primary charging control
DC constant current control: set by potential control
Grid bias control
DC constant voltage control: fixed by varistor
Control value: 850 V (approx.)
Developing bias control
AC constant voltage control: on/off control only
Voltage: 1500 Vp-p (approx.)
Frequency: 2.7 kHz (approx.)
DC constant voltage control: set by potential control
Control value: 0 to 600 V (approx.)
Dust-collecting roller bias control
DC non-control
Voltage: -1000 V (approx.)
Pre-transfer charging control
AC constant voltage control: fuzzy by environment sensor
DC constant current control: on/off control only
Transfer charging control
DC current control: fuzzy control by environment sensor
Separation charging control
AC constant voltage control
DC constant current control: fuzzy control by environment
sensor and to suit density of original (drum surface potential)
