Question about Canon NP 6551 Black and White Copier
Your problem is most likely caused by dirty optics. Place a sheet of paper on the glass & make 1 copy with the lid up. Look under the glass at the mirrors on the scanner & see if there is any dust on them. If so,turn the copier off & unplug it from the wall, remove the glass & wipe off the mirrors with a DRY cotton rag. There are 3 mirrors on the scanner assy. There is also three mirrors under the lens cover that should also be cleaned. After cleaning the optics, make a test copy.If your copies are still to dark, press the additional functions key & select exposure adjustment. You can lighten/darken all copies by changing this setting. If you have any problems or questions my email is email@example.com Good Luck!!
