[Misc] Toner on background of paper CANON IR ADV C9060PRO

[Cmp4you]

An older imagerunner C9060 pro has a lot of toner particles on the background of the paper. Corona and toner collection tray have been cleaned.
The amount of particles increases with increased page number of the job. The first page looks good, the 10th page is full of black & magenta toner particles.
Is it static? Or corona? Toner is genuine and new.

I am glad for any answer I can get!
Stay healthy!

Have you tried replacing drum units of the colors involved? They appear like leaking units. For instance the image shows that you see those droplets even if you don't have original document on platen glass.

I have not replaced the drums yet. The colors involved are magenta (worst), cyan, black. How can this happen with all drums at once? Can this be static that attracts the toner? This issue occured quite fast, from one print to another.
How comes, that the first page looks good, but the other pages get progressively worse? Static building up?

I have checked the counters on drums and devs. All under 20%, so relatively new.

I think I get your point. But the other side is: how should only magenta be worst, cyan and black, and yellow OK, when the issue is a static buildup? I think the static eliminator works on all colors.
It will be worthwhile not ruling some culprits out until you try them. Also what is your assurance of the quality of the toners?

I have tried b/w prints. First page is good, 10th page is bad. Dots on the paper are black. I checked the humidity: . --> 13% seems really low for humidity and might be causing the static or am I wrong? I checked the log and the humidity shows 13% for the last 4-5 days (issue is known for atleast 3 days). Before it was at 20-26%.

The issue occured with a low running magenta toner and a new magenta toner I put in, before the old toner completely ran out (<5%). The toners in the machine get changed quite often due to many prints, so the toner shouldn't have been too old. We have never had problems with the toner of our genuine supplier in the last years. And now the issue should be occuring on all colors? Hm would be strange. Same for the devs and drums.

I would agree with you that 13% humidity is not ideal for sure. If the drums and devs are only 20% have you tried to redo DPC for drums and reinitialize devs as well as perform TDC adjustments? You should be sure the patch read sensors are clean also.

I had this happen on a C7010VP - issue I'm almost certain is humidity. Customer had like under 7% humidity. Seemed to get better in the summer months with natural humidity but I could never really fix it. Customer didn't want to put it in a proper room like he was told. What are you gonna do.

Oh, 7% isn't too much...the issue is, that the room where the machine is located at is really huge (hard to change hum. levels) and the machine is standing there for 10 years now. Don't really know, if the issue occured in the past.
I will need to wait for other weather conditions, or get the levels to rise to atleast 20-25%.
Thank you for your input and your experience!

Could you specify DPC for drums & tdc adjustments? Which service mode should I look up? My service manual is in another language and it is difficult to translate the terms..
Thank you for your time!

PVCONT-Y/M/C/K is at -1000V. Is this normal? Default value should be at 20-120V.

This is what I've done for years when installing drums and devs. I'll try to recite it from memory and hopefully if I miss a step someone will correct me.
First step is to go into service mode under Copier> Function> Install> find AINR and turn it off, or set to 0. Turn machine off. Make sure the patch read sensors are clean. They're located above the ITB assy on the right side and each of the 3 sensors will have a white shutter covering it. Careful opening the shutters as they are easy to pop out of position and they are all tied together so that when one is opened the other 2 will be open too. Center sensor is for reading density patches and fr and rr sensors are for registration patches.
After sensors cleaned you would replace components that are worn out. In your case, with drums and devs at 20% just turn on the machine and let it go Ready. You will not hear much for warm up rotations as you disabled that earlier (AINR). Then go into service mode Copier> Function> DPC and choose each drum and execute the adjustment OK. You can also do all 4 drums for future reference if all replaced at same time. Then with new devs you would go to Copier> Function> Install> and perform Stir, Initialize and lastly TD Adjust for each new unit. With slightly used devs I would do Initialize for each dev first, then perform TD Adjust for each as a last step. After last TD Adjustment go back and set AINR to 0 again and turn off machine. Turn back on and hopefully you will notice full initial rotations and it will come Ready. Then perform Auto Gradation under Settings/Registration for both Plain and Heavy stock. And lastly, calibrate the RIP or Fiery processor if it uses one.
Hope this helps if you try it. Not sure of your skill set with Canons so I'm just sharing how I've done it for years. I started on Canon when liquids were the new thing, Models 30,50 and 60. And remember... you can't hurt broke, right?
