Troubleshooting fuzzy line in originating in cyan drum (Pro C5110S/Pro C5100S)
This section provides troubleshooting procedures for the image quality issue known as "fuzzy lines",
particularly for those originating in the Cyan station.
Symptom
Unwanted lines appear on the printouts in 189mm pitch (=drum circumference) in main scan
direction. The lines could either be solid or interrupted as shown below.
Solid lines
• To check if the lines are originating in the Cyan station, print out a solid image in 100% Cyan.
Cause
The electrical charge applied to the ITB is discharged when the ITB passes under the Cyan drum.
This is because the ITB is closer to the Cyan drum than other drums when the ITB retracts.
Image Quality
Interrupted lines
