Density Adjustment During Printing - Canon iR5000i Service Manual

2.6.2 Density Adjustment During Printing

The developing bias is raised to decrease the print density. Too high a developing bias,
however, will result in hazy images. Near the lower limit of the developing bias, the changes
in the developing bias are corrected and correction is also executed as part of image process-
ing (thickening).
