DocuColor 7000AP/8000AP Decurler Adjustment

Decurler Adjustment

Determine if curl is upward (“cupped”) or downward (“bridged”).

KEY POINT: While paper curl is caused by many variables, it is
important to understand that the preset and E Table Decurler
profile settings use lookup tables for curl control that are based on
the job’s toner area coverage and the printer’s humidity values,
only.
