16.3.2 Image Faults

16.3.2.1 Blank Image

16.3.2.1.1 Blank page is output when printing scanned image

original
[ Manual-related ]
Cause
This symptom occurs because toner replenishment cannot keep pace with toner consumption.
Field Remedy
In service mode (Level 2) [COPIER> Option> BODY> SLV-UP], select "1" or "2".
Note: The drum life will be shortened as a negative effect of "1". In addition to this, the print productivity will
decrease as a negative effect of "2".
16.3.2.3.2 Density fluctuation: appreciable after outputting images of a high color ratio continuously
Cause
The balance in toner inside the developing assembly fails; when the image stabilization mechanism goes ON in
this condition, the machine tends to base its contrast potential on the existing condition. When the balance
between the toner and the carrier inside the developing assembly returns, the density fluctuates in relation to the
selected contrast potential.
Field Remedy
Execute the following in user mode: adjust/clean>auto gradation correction>full correction
