Backgrounds of printed pages are grey

Printed or copied pages have a grey background. The cartridge was changed and that helped for a while, then the poor copies returned.

SOURCE: black smudge streaks on rightside of printed/copied material

Can only be two things the drum or the fuser. More than likely drum they last about 4 toners i think.

Learn the art of getting a page to stop halfway threw printing, you want to stop the page after the drum has put a image on the paper but before paper has gone threw the fuser (hotbit).

Once you have mastered the position correctly by stopping the printing by opening the door and removing drum/toner cartridge, to reveal the paper that is printed but can be rubbed off, we will know if marks are coming from the drum (you will see them) or from the fuser, if print is fine.

Change out the toner first and then the drum. Also be sure there is not excess toner underneath where the toner is installed. If so clean that out with a dry cloth.

SOURCE: Black lines down on printed page

This is caused by dirt/debrise on the ADF (automatic document feeder) scanner glass. You need to open up the feeder where your originals are fed in and look for a strip of glass that runs from front to back. It is about an inch or so wide. You need to clean this glass to get rid of the lines. Some models have this glass just to the left of the large main glass, but in your case I beleive it is in the feeder itself.
Good Luck.

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.

I have one problem with hp laserjet P4014n printing all paper black. the background is black all but word are showing can someone help me in this


If your background is "Black" it's going to print it all black, change your background color to "Gray" and your machine will then print a gray background instead of black. Also note that when you print a black background your toner life expectancy will be no where your expected yield ratio is. Average yield is 5% for X (X meaning size of cartridge) amount of printed pages. If your printing a black background your utilizing 100% yield coverage. Not sure if this is the answer your looking for. However basic black and white printing with a black background will print the page completely black.

Printing black on paper


Some of these machines will allow you to printe a grey scale test copy.
This will readjust the fax machine back to a nominal mode.
Not knowing how old or how long the machine has been serviced, background can be caused by dirty optics somewhere in the machine.
A remanufactured drum unit can cause this type of problem, (defective unit)
Competitive toner in the toner unit can cause poor copy quality.
Reinstall the old cartrige and see if the problem changes.
Not knowing if the machine has a seperate drum unit and developer housing, it would be hard to answer anything else.

Grey/dirty background on prints


Try cleaning the ETB.  Go to the secondary service menu (press the left arrow and stop buttons on the panel simultaneously until you see the secondary service menu), press the left button until you see "Clean ETB," then press the green check button to start the cleaning.  You may need to do this several times to get it clean.

Hi,

if you have a laser printer you may need to clean the printer or install a new drum cartridge, if it is ink-jet you will have to clean the bottom of the ink cradle it sound like you getting grey background from a toner/drum cartridge.
