Dark copies in normal mode.

Are you printing in "draft" mode? That is always light. Try "normal" or "quality". Also make sure you have selected the correct paper type. "Plain paper" is what most paper is. Photo paper is quite different, and photo paper setting will not work correctly on plain paper.

The dark quality is definitely linked to a light intensity problem. If the scanner lamp is operating properly then check for any reflective surfaces near the scanning lamp and clean those. It only takes a light film of dust to make copies dark. Be careful around the lamp, it is delicate.

Open the printer driver setup window
Select the manual color adjustment (or if already in manual and it had initially been printing fine, you may opt to select Auto)
On the Main tab, select Manual for Color/Intensity, and click Set....
The Manual Color Adjustment dialog box opens.
Specify the brightness

Select Light, Normal, or Dark for Brightness, and click OK.
The current settings are displayed in the settings preview on the left side of the printer driver.
Complete the setup
Click OK on the Main tab.
When you execute print, the data is printed at the specified brightness.

The only changes you can make are in the printer preferences menu, so if you have lightened it up there you have made the only adjustment allowed or provided for.

To adjust the contrast, Press Darkness. Each time you press the button, the LED labeled with the selected mode turns on. You can choose from the following darkness modes:
1>Lighten: works well with dark print.
2>Normal: works well with standard typed or printed documents.
3>Darken: works well with light print or faint pencil markings.

It's never going to be perfect (unless the background is quite light in colour), because the copier basically "sees" the coloured background as "gray", and the darker the background the more "gray" it looks. Try setting the original type to "photo" mode, and then adjusting the exposure a little lighter/darker....that's all you can basically do.

yes.there is a adjust ment.go to printer properties and there printing preferences and there adjust the print quality to normal which is set on beat mode so the prints are comming extra dark.

This maybe your cleaning blade, your drum or the fuser unit....the best way to find out is to make a copy a to stop it before it's getting to the fuser unit ( that's the thing very hot). If you see your border it's your cleaning or drum...But when you replace a drum you must replace the cleaning blade to !
