HRe: WorkCentre 6505 printing black splotches on page

Did you ever figure out what the issue was?  I have exactly the same problem.  Following this thread and do let me know if you figure it out!  Thanks in advance!

Your problem is not from the toner cartridge, so do not replace it.

Thank you. I used a soft cloth with isopropyl alcohol and cleaned as much of those three items as I could and the problem seems to be a little better. I am running low on cyan ink and since the splotches always happen in very dark areas, I'm wondering if getting a new cyan cartridge might help too so will try that. I don't want to go to the expense of replacing the fuser, imaging unit, or the transfer unit unless I can difinitively nail the problem down to one of those. Thank you for your help with this difficult-to-solve problem.

Hi,

If is not from the fuser it could be from on edrum of the iamaging unit or from the transfer belt.

Also, when I rub my finger over the black area where the ink was lifted, it does smudge. (I misspelled isopropyl alcohol)

I did go ahead and use a clean rag with isopropal alcohol and wipe down the fuser and also another rubber roller adjacent to the fuser. When I printed another test page the problem was still there. The ink on the solid jellybean pulled off and redeposited a couple inches below it on the page.

Hi Gabi, thank you for your comment. I removed the the fuser assembly and can see a small organge roller inside. When I turn the gears I can see a sort of line and a little bit of damage on the organge (fuser?) surface but it does not align with where I'm getting ink blotches on my page as shown in the picture on my original post. Also, the blotches of ink only occur where the print is very dark/saturated with color. This makes me skeptical that it is the fuser. Is there any safe way for me to clean the fuser to test this? Thank you again for your input!  If you or others have any other suggestions I would appreciate it. Thanks.

Hi,

Check the surface of the fuser, it is possible to be scratched.

My Xerox WorkCentre 6505 is printing raised dark splotches of ink on the page. It appears that where there are areas of very saturated dark color, the ink is being pulled from those sections and deposited lower on the page as a reverse image. The ink splotches are raised but do NOT smudge when I run my finger over them. Below shows a test print.  I have zoomed in and circled the areas I am talking about on the right of the page to illustrate the problem. (You may need to scroll down to see the entire print.) I have gone under the "maintenance" section on the printer and ran the software tools for "clean developer", "toner refresh" and "imaging unit refresh" with no improvement.  I then opened the printer and manually attempted to clean the imaging unit, vacuumed out some toner dust in that area, plus wipe off the exposed surface of the transfer bed with a lint-free dry cloth to no avail. I cannot figure out how to remove the transfer belt to clean its entire surface in case that is the problem. 

I am not very knowledgeable about laser printer maintenance and have done all I can do. Perhaps someone here has run into this problem before and can help me.

Thank you for any help or suggestions!
