CRG-BS-C Charging bias setting value (C)
[When used]
Low/high image density or fogging occurs but the problem cannot be solved by changing the density setting and performing special printing process.
[Adjustment method]
- When fogging occurs, it may be eliminated by increasing the setting value.
- Increase the setting value to slightly lower the image density.
- Decrease the setting value to slightly increase the image density.
Setting range: -10 to 10 (Unit: 20V)
[Factory setting value/Value after RAM clearing: 0]
CRG-BS-K Charging bias setting value (Bk)
[When used]
Low/high image density or fogging occurs but the problem cannot be solved by changing the density setting and performing special printing process.
[Adjustment method]
- When fogging occurs, it may be eliminated by increasing the setting value.
- Increase the setting value to slightly lower the image density.
- Decrease the setting value to slightly increase the image density.
Setting range: -10 to 10 (Unit: 20V)
[Factory setting value/Value after RAM clearing: 0]
DEV-BS-Y Developing bias setting value (Y)
[When used]
Low/high image density or fogging occurs but the problem cannot be eliminated by changing the density setting and performing special printing
process.
[Adjustment method]
- Increase the setting value to increase the image density.
- Decrease the setting value to decrease the image density.
- When fogging occurs, it may be eliminated by decreasing the setting value.
Setting range: -10 to 10 (Unit: 20V)
[Factory setting value/Value after RAM clearing: 0]
DEV-BS-M Developing bias setting value (M)
[When used]
Low/high image density or fogging occurs but the problem cannot be eliminated by changing the density setting and performing special printing
process.
[Adjustment method]
- Increase the setting value to increase the image density.
- Decrease the setting value to decrease the image density.
- When fogging occurs, it may be eliminated by decreasing the setting value.
Setting range: -10 to 10 (Unit: 20V)
[Factory setting value/Value after RAM clearing: 0]
DEV-BS-C Developing bias setting value (C)
[When used]
Low/high image density or fogging occurs but the problem cannot be eliminated by changing the density setting and performing special printing
process.
[Adjustment method]
- Increase the setting value to increase the image density.
- Decrease the setting value to decrease the image density.
- When fogging occurs, it may be eliminated by decreasing the setting value.
Setting range: -10 to 10 (Unit: 20V)
[Factory setting value/Value after RAM clearing: 0]
DEV-BS-K Developing bias setting value (Bk)
[When used]
Low/high image density or fogging occurs but the problem cannot be eliminated by changing the density setting and performing special printing
process.
[Adjustment method]
- Increase the setting value to increase the image density.
- Decrease the setting value to decrease the image density.
- When fogging occurs, it may be eliminated by decreasing the setting value.
Setting range: -10 to 10 (Unit: 20V)
[Factory setting value/Value after RAM clearing: 0]
FRT-TS-Y Transfer bias front side setting value (Y)
[When used]
An image failure occurs depending on the type or condition of the paper AND the problem cannot be eliminated by performing special printing
process.
[Adjustment method]
- The problem may be eliminated by changing the setting value.
- Increase the setting value. (Effective for toner scatter/dotted image)
- Decrease the setting value. (Effective for white dots/white flower patches/image with high granularity in halftone mode)
Setting range: -30 to 40 (Unit: 50V)
- It is preferable to enter values in the condition of "M <= C <= Y <= K".
