Compulsory execution of half-tone density correction
NORM NORMAL : Standard mode grid bias (350 - 1150V)
T/S T/S : Toner save mode grid bias (350 - 1150V)
PHOT PHOTO : Photo mode grid bias (350 - 1150V)
GB_A GB ADJUST : Grid bias correction value after measurement (
±
0
∼
999V)
TARG TARGET : Patch/foundation, standard patch value when foundation is 255
(255= foundation)
ID_G ID GAIN : Image density sensor gain rank in execution (1
∼
7)
MARK MARK : Drum mark sensor mark level in execution (0
∼
255, 255=5V)
MARB MARK B : Drum mark sensor surface level in execution (0
∼
255, 255=5V)
DM_G DM GAIN : Drum mark sensor gain rank in execution (1

7)
BAS1, 2, 3 BASE1, 2, 3 : Drum surface image density sensor level in execution (0

l l : Vg correction coefficient
m m : Dirt correction coefficient
n n : Film wear correction coefficient
M1 M1 : Dirt correction coefficient (M1)
M2 M2 : Dirt correction coefficient (M2)
l * m * n l * m * n : Vc1 correction coefficient
07 Drum mark sensor/image density sensor gain select check
The image density sensor level can be checked for selection of each gain rank. : 0~255, 255 = 5V

Since the max. difference in amplifier rates between two gains is 132%, supposing the max. sensor
input is 4.8V, the gain rank is increased by +1 for 3.6V.
