Konica c454 FAINT COPIES

[Jama]

Hy engineers,
I have konica c454, has faint copies than it was previously printing dark copies. Toner used same as previous, drums and all imaging units good as before👉 mileage still low. Laser unit cleaned OK. But slightly improved after cleaning laser. What could be problem rather than high voltage board. Any calibration to increase dark copy and printout? Especially black and white prints.

Post CMYK halftone patterns at 255 and 128 density. Clean IDC sensors, clean drum coronas and make Stabilization and gradations.
