Clean the laser unit

The fact that the font report is ok ,it means the laser unit is ok.
Try to clean the optical fibre on the scanner with a cotton wool or clean cloth with spirit.
If the copy is still faint clean the transfer roller as well.
If no copy improvement still,under service mode go to COPIER>ADJUST>DEVELOP and make adjustments.

Had same issue a while back. Didn't make sense. Asked for help and one of our techs had battled the same issue a while ago. In my case going into full automatic gradation setting took care of it. I had to run it twice, each time it got much better. Don't ask me why, just try it and see if it works for you too.

The way I read it was the font prints are OK (to me means not great), would be easier to help if we could see samples.
Guess I shouldn`t assume that optics were cleaned and auto gradation ran.
