DEV-DC-Y/M/C/K
Output value (current value) of target developing DC voltage (Y/M/C/K)
[Checking point]
Optical value: 250 to 700
If the value is out of optical renge, replace the charging assembly and potential sejsot
2
D-CRNT-P/S
Measured value of dark current at patch detection ATR control (P wave/S wave)
[Checking point]
Optical value: P30 to 90/S100 to 250)
If the value is out of optical renge, replace the patch sensor
2
P-SENS-S
Detected value of light intensity for basis value (drum) at patch detection ATR control (S wave)
[Checking point]
Optical value: 200 to 600
If the value is out of optical renge, replace the patch sensor.
2
DENS-Y/M/C-H
To display the history of measured value of light ATR sensor (Y/M/C color, last 8 cases)
[Checking point]
Optical value: 01F4 to FED4
- If the value exceeds the upper limit (FED4 or more), copy 10 sheets of solid image.
- If the value exceeds the lower limit (01F4 or less), copy 10 sheets of blank image.
2
DS-S-Y/M/C/K-H
To display the result history of patch image detection (Y/M/C/K color, last 8 cases)
[Checking point]
Optical value: 00C8 to 01C2
- If the value exceeds the upper limit (01C2 or more), copy 10 sheets of solid image.
- If the value exceeds the lower limit (00C8 or less), copy 10 sheets of blank image.
2
P-LED-DA
To display the D/A setting value of patch image sensor LED
[Checking point]
Optical value: 80 to 255
If the value is out of optical renge, replace the patch sensor.
2
SPL-LG-Y/M/C
Supply history Y/M/C color
To display the supply history of last 8 cases
Display renge: 00 to 50 (0 to 800g)
[Checking point]
Optical value: 0 to 5
Since it is fixed from 0 to 5 on engine control, other values will not appear.
2

Correct value: 250 to 450
2
D-L-TRGT
Target value of the developer density (L)
2
DEV-DC-L
Output value of the target developing DC voltage (L) (Current value)
2
DENS-L-H
History of the light ATR sensor measurement values (L, last 8 values)
2
SPL-LG-L
Supply history of L color
Display the last 8 supplies.
Display range: 00 to 50 (0 to 800g)
2
DS-S-L-H
History of the patch image detection results (L, last 8 values)
2
