● Black Band Control
This control maintains the cleaning performance by providing sufficient amount of toner to the
edge of the Cleaning Blade.
NOTE:
Friction coefficient between the Blade and the Drum is increased unless sufficient
amount of toner is applied on the Drum Cleaning Blade, which causes ride-up of the
Blade. Although toner is properly applied to the center of the Blade by normal cleaning
operation, toner is supplied insufficiently to the edge of the Blade.
Execution timing
• Last rotation after the specified number of sheets
*1
has been fed since execution of the last
black band control.

*1: This value can be changed in service mode.
