44 08 Grid voltage correction, optical dirt correction, drum membrane decrease correction data display
Used to display each correction data of the grid voltage correction, the optical dirt correction, and the drum
membrane decrease correction on the copy quantity display.
Since there are two or more display items, the third digit is used to make distinction between the light reception
level and the original judgment level, and the lower two digits are used to display the data.
The display is selected by the magnification ratio key.
Copy quantity display
Display data
3rd digit 2nd, 1st digits
A 8 ∼ 99 Patch forming grid voltage (initial value)
Gird voltage when the display value is 50 = 410V
When the display value is decreased by 1, the grid voltage is decreased
by 5V.
When the display value is increased by 1, the grid voltage is increased by
5V.
b 1 ∼ 99 Normal mode grid voltage (initial value)
Display value × 10V is the grid voltage output.
C 0
∼
99 Optical dirt correction reference value
The AE sensor input value measured after execution of SIM 46-1.
(Converted into a decimal number and displayed.)
d 0 ∼ 99 Drum rotating time (accumulated value)
When the display value is increased by 1, it corresponds to one hour.
E 0 ∼ 99 DV unit (black) rotating time (accumulated value)
When the display value is increased by 1, it corresponds to one hour.
09 Grid voltage correction, optical dirt correction, drum membrane decrease correction data display (the newest value)
Used to display each correction data of the grid voltage correction, the optical dirt correction, and the drum
membrane decrease correction on the copy quantity display.
Since there are two or more display items, the third digit is used to make distinction between the light reception
level and the original judgment level, and the lower two digits are used to display the data.
The display is selected by the magnification ratio key.
