Ⅲ. Troubleshooting
Error Vertical Line and Band
[Description ]1. Straight thin black vertical line occurs in the printing.
2. Dark black vertical band occur in the printing.
[Wrong Part]1. LSU
2. Developer Unit
[Check and Cause]
1. Damaged develop roller in the Developer.
2. Deformed Doctor-blade
[Solution]
1. If causes 1 and 2 occur in the developer unit, replace the
developer and try to print out.
[Etc]
Trouble & Solution
Error Dark Image or black
