I am at my wits end trying to figure out what is causing a faded color issue with my 5100cn. I thought it was a toner issue at first, so I replaced all of the toner in it that was getting near empty to see if that would help. But no, still having the same issue. If I print out black text it comes out find, but anything with color is faded. The %20 color tests all show the fading, but the grind test page for some reason doesn't. I'll include likes to all of my test pages on here.. could someone please take a look and give me some ideas for what to try next? Thanks!
The last page (Gradation test page) tells me all I need to see. The color clutch in your developer drive assembly has failed, that's why you only get the leading edges of color, but black appears OK.
The part you need to call and purchase is the Developer Drive Assy, P/N H6702.
Ugh, that's what I was afraid of. Thanks for confirming it, though. I saw other people complaining about lack of instructions for installing the developer on here.. is this part easily replaceable by an end user, and are there instructions online? I'm handy with PC assembly but I'm not too experienced with printers.
Sent you a PM.....
I think a friend of mine has the same problem. She prints multiple copies of the same page and the first page comes out fine but the remainder start fading more and more. Black comes out fine, it is just the color that has the problem. Does this sound like the same resolution will help her? Thx.
If just the top edge of colors print and immediately fades out, and black prints fine, then yes... sounds like the same problem.
Thanks Llynster. Hmmm, then maybe not. She sets the printer to print 6 copies and the first page prints correctly but from then on the pages colors begin to fade more and more like you are reducing the density on each page until you hit 0. Any help?
This might still be the color clutch (part of the Developer Drive Assy). Sometimes the clutch doesn't fail completely, but begins to slip in a progressively worse manner as it's running.
NO guarantee's. One of the best tests to use is the "Gradation" test page in customer diagnostic mode.
Thanks. I am going to their house today and will let you know the results.
If you have the means, please upload an image here and tell me what you named it.... pictures speak a thousand words.
I had a similar problem except mine is with the black, the color seems ok but the black is very faded, almost unlegible. We just replaced the black toner, fuser kit, drum kit, and transfer roller and still the darn thing is printing black extremely faded.
This has been very frustrating, any assistance would be great!
Pull out the imaging drum unit and have a look at the black mag roller. Does the "fuzzy" coating seem less dense than the colors?
I'm wondering if you have a problem with the toner supply motor.
What's the page count on this printer?
Hi, I know that this was a lot time ago but I have the same printer as
you and I believe the same problem. If I print something with black
& color the color comes out super fine but the black comes out very
faint. I did a dev cleaning on the black toner and it start doing a
very grinding sound from it. Did you manage to fix this issue??
Thanks for any help that you can give me.
It sounds to me like the black toner motor gearbox has stripped a few teeth. It's part of the Toner Dispenser Assy. Dell p/n G6599 (for 5100cn), TF123 (for 5110cn)
Do you know how to use the diagnostics mode in the printer? If so please run Digital Output test DO-4e. This will run the black toner drive motor. Run it no longer than about 15 seconds. Please let me know what you hear. You can compare what you hear with any of the other toner motors; DO-48(Y), -4a(M), -4c(C)
Are you using genuine Dell toner? If not, this is probably only the beginning of more problems. The company that makes these printers for Dell has a trade secret on the toner formulation. Compared with 3rd party toners, it is not the same and they will eventually ruin the inner workings of the printer.
My 5100cn has black fading. It worked great until we changed the black cartridge, then the fading started. I checked with a second cartridge with the same results. The printer has 200K pages, all with Dell toner. When I run the DO-4e test, there is no grinding, in fact it may be a bit quieter than the DO-4c. After running -4e there was a slight improvement. Any suggestions?
Because you indicated the print density improved after running test DO-4e, this tells me you may have some blockage in the black auger tube. This tube is the longest tube and runs from the back of the machine down to the lowest developer unit. Think of it as an artery being blocked by cholesteral.
Let me have a couple days to think of the best way to clean this out. You handy with a #2 Phillips screwdriver?
