Black copies are coming out faded. How do I fix this? I have already changed the toner and the waste toner bucket.


Does this happen when you print? Not Copy. Does the internal prints come out OK configuration page, meter count, etc.? Did you change the drum unit? Or is the drum unit and toner cartridge one in the same, drum would be blue or green, puts the image on the paper so be careful to not touch it. waste bucket really not a player in this situation.

Poor copy quality - smudgy copies - changed toner - still the same.


check your OPC drum life, if you have a poor quality with a new cartridge installed (light copy, dirty copy) the opc drum must be replaced, check you machine counter if you have reach 100k copies you need to replace the drum, if you are using a new OPC DRUM, you need to clean the machine, you have to call for service because there is many parts that muat removed to clean properly.

Xerox 416P faded copies


Remove the glass and thoroughly clean the lamp, mirrors and lens. Also the glass on both sides. If that does not work, remove the toner and drum, look inside the machine for a small opening about 8 inches long and a quarter inch wide. That is the laser window. It may also need cleaned. It is possible the laser needs to be removed and cleaned.
I am not sure, can you print reports on the p model? If so make a printed page and tell me if they look fine.
What you have to remember on a digital copier is when the optics get dirty , the image gets lighter.

Bad photo quality after changing drum


your laser printer
1) print color quality is now distorted that means print skew (technician called)
2) print tint means the print color not enough density,
3) print mottle means print dirty
you may try
1) print distorted--- find out the skew adjustment from your printer manu, it is adjust the image before transfer to the drum.
2) print skew could be happened when the drum replace install not very accurate, so install it more carefully.
3) print tint---you may increase print density from the manu, not fix,
4) print tint---the toner caridge near life cycle or using the less compatible toner. so you have change the quality toner or cartridge (if near life cycle) to improve quality photo print
5)print mottle---toner quality ? or cartridge near life cycle also cause print dirty paper,

How do I clean white or black spots on printed documents? Description: First make 10 to 15 copies of a blank, white sheet of paper.
If you still see the spots on printed documents after making multiple copies, clean the drum unit as follows:

  1. Remove the drum unit and toner cartridge assembly, and then remove the toner cartridge from the drum unit.
  2. Position the print sample in front of the drum unit so you will know the exact position on the drum that is causing the poor print.
  3. all-ug-19.gif
  4. Turn the black gear on the drum as you check the surface of the OPC drum.
    The OPC drum is photosensitive so do not touch it with your fingers.
  5. all-ug-20.gif
  6. When you find the substance on the drum surface that matches the print sample, gently dab the surface of the OPC drum with a cotton swab that is lightly dampened with isopropyl alcohol.
  7. Note
      • Do not use a scrubbing or wiping motion because this might damage the drum.
        all-ug-21.gif
      • Do not try to clean the surface of the OPC drum with a sharp object, such as a ball-point pen, because this might cause permanent damage to the drum unit.
  8. If the print quality still has not improved you need to install a new drum.

1710n Printer - poor print quality


You need to inspect your drum unit as well. If you can line up the marks on your page with the drum then you will need to replace the drum unit. If you donot find any problem with the drum unit then check the fuser unit on the back of the printer. Be very careful when checking the fuser since it is EXTREMELY hot. Good Luck

Improve print quality


If you have changed drum AND toner, and reset drum count, cleaned scan slit glass on lit then only other thing to clean that can cause dirty prints is laser glass, (remove drum, inside where drum goes there is a slit the rund width of printer on inside middle "ceiling"

The orange piece I take it is the lower heat roller at rear, cleaning this is not going to fix anything.. this area called the fuser sometimes the fuser wears the coating off the upper heat roller (above orange one) and leaves like a smudge mark on prints, like I say cleaning wont fix replacingfuser with new would be what is required

I find a lot of grey shading on prints on this model are from faulty toner cartridges, next is drum then worn fuser roller... Stop a print half way (timing) in machine remove drum and look at print, after drum but pre fuser ,to see if image is ok before entering fuser, then we know if that is your problem
