Image Density Adjustment Factor (SP34)
From:
QAC Field Information Dept.
Classification:
The Image Density Adjustment Factor (SP34) criteria have been changed to achieve
better output results. Previously, both the development bias and the exposure lamp
settings were increased or decreased. The new system now only changes the exposure
lamp setting to adjust image density. Taking this into account, please correct the related
pages in your service manual that contain the table for this SP mode.
