HP2600n ? soft grainy texture printing in background
We had this problem once before, it was even on the troubleshooting list as, "Toner appears around the printed characters". Last time, it ended up that HP just told us to exchange it, but now we don't have that option. The new printer we exchanged it for is doing the same thing. I remember being told by HP support to clean the ETB many times and have done so, but the problem does not seem to go away. Any ideas of other things to try??? __________
"inside the image tranfer belt unit,there have 4 rollers ,just
clean both end of roller and also the contact metal spring clean that
and bend it little bit make sure it contact perfect, should be take
care your problem" I apologize, I am a designer and have never done any maintenance
like you are talking, how do I do this, is there anywhere that provides
diagrams or steps of how to take the rollers out? What do I clean them

Right-click the product icon, and click Printing Preferences to open the Printing Preferences window.
Click the Paper/Quality tab.
Check the paper or media type setting.
Find the Type is: drop-down list.Figure 1: 'Type is:' drop-down list in the Printing Preferences window'Type is:' drop-down list in the Printing Preferences window, Paper/Quality tab (screenshot)
Select the paper or media type you are using.
For thinner paper, select Light , Thin , or Vellum .
For thicker paper, select Heavy or Thick .
NOTE:HP does not recommend the use of heavily textured paper, extremely thin paper, or paper with a basis weight heavier than 90 g/m2 (24 lb).
Make sure the paper or media type setting is appropriate for the fuser temperature.NOTE:Unlike ink printers, laser printers use heat to fuse a plastic toner to the surface of the paper. Make sure to use heat-resistant paper, and labels and envelopes that use adhesives compatible with the heat and pressure of the product's fusing process.
If you are experiencing any issues in the following list, adjust the setting.
If the paper is curled or wavy , try the following:
Decrease the fuser temperature setting. To do this, select Light ,Thin , or Transparency .
Use the archive print feature to improve toner fusing. To do this, select Archive or Bond .
If the printout has areas of fuzzy or dark print , or toner scatter , increase the fuser temperature setting.
Select Heavy or Thick .If this does not resolve the fuzzy, dark print, or toner scatter issues, use a lower basis weight or thinner paper.
Click Apply .
Step three: Check the print density settingsFollow these steps to check the print density settings in Printing Preferences and in Properties.
In the Printing Preferences window, click the Paper/Quality tab, and find the Print Quality section.Figure 2: 'Print Quality' section in the Printing Preferences window'Print Quality' section in the Printing Preferences window, Paper/Quality tab (screenshot)

If the printout has light, dull or faded areas , increase the print density setting.To do this, slide the bar to the right .
Click Apply , click OK , and then close the Properties window.
This can depend on if they are white or black lines and if you can feel a texture on the paper. Most often the cause is a bad toner cartridge. If you are using generic toner cartridges, I would suggest trying a new HP one instead to see if it clears up. If you feel a deep texture to it, the fusing unit may be wearing out and need to be replaced.
This could be caused by a couple of things. The first one is the toner cartridge. A defective or low toner cartridge can cause light "grainy" looking copies. If you have a spare toner cartridge try that first. The second possibility is dirty scanner optics. The scanner bar that lights up under the glass and moves back and forth has 3 mirrors on it. When they get dirty is causes your scanned image (before it gets copied) to appear light and patchy looking. The glass must be removed by removing the 4 screws on the left hand side. Then the scanner can be pulled out and the 3 mirrors cleaned. If you have the machine hooked up to a computer to be able to print then these mirrors will NOT affect PC prints. If PC prints are grainy then that would point to the toner. The dirty mirrors will only effect the copies.
Good Luck and Thank You for using Fixya.
We are having a contest this month that is based on positive testimonials. If my solution is helpful please leave a short testimonial for me.
Inspect imaging drums for any signs of leakage or excess toner that could be falling onto the print as it travels though the printer. Any leaking imaging drums should be replaced.
Verify environmental conditions. See article Dealing with humidity, humidifiers. If the environmental conditions are not within the specified range, the printer should be moved before trying to troubleshoot the cause to the background toner.
Determine if any of the imaging drums were exposed to light for an extended period of time (more than 10 minutes). If so, then Replace the imaging drum. (Xerox is not responsible for any imaging drums that have been damaged by over exposure to light.)
Additional Recommendations: Background toner may increase, if printing occurs at temperatures towards the higher end of the specified operating temperature range. For this reason, it is recommended that the printer be moved to another area if at all possible.
In addition, very smooth media types such as glossy; allow toner to more easily scatter about the page prior to becoming fused. Try using a less smooth media if at all possible.
