Re: C1060 with toner pile-up on the 2nd Transfer Unit
Well, as the supply chain unpredictability persists, the toner bottles in stock are sealed products direct from Japan? Not all of them, but definitely the magenta. The bottles are keyed differently as well...Originally Posted by blackcat4866
Anyway, it's Friday! Machine is functional and I will no doubt need to clean it again before figuring it out. It's a Monday problem now.... LOL
I'll report my findings then, thanks!
If that filter box is at 97% you definitely need to replace it. They always look fine when removed but the internal filter is for sure clogged up. Also, while the filter box is removed, get your vacuum out with a crevice nozzle and reach back behind the process drawer and clean out those suction ports (8 of them). When the filter and ports get clogged these machines will start blowing toner all over the place. Particularly magenta.
Re: C1060 with toner pile-up on the 2nd Transfer Unit
Yes, Sir! Go with the simple fix first. LOL
When I first saw the dusting throughout the unit, I made sure to clean out the inlets. The ITB was certainly distressed and the majority of the problem. Replacing the TBCU was due as well. Combined it cleaned everything up except this magenta leak. I will revisit the inlets, be thorough this time and replace the filter box.
I'll report the results once I have everything done and running.
Re: C1060 with toner pile-up on the 2nd Transfer Unit
OK, got the new Filter Box and broke down the Process Unit and completed a thorough cleaning, including the Dust Proof Glass (you'll know why I point this out by reading the rest).

NOTE: Out of curiosity I weighed the old Filter Box vs. the new and it was definitely heavier. Dumped it and magenta was spewing out. EWWWW.
Picked a job out that was a good sized run of 800+ sheets. Loaded the tray with 200 sheets (to break the run) and went to town... After each reload, I check the 2nd Transfer for deposits. Yep, magenta's still there. As the fate would have it, a few sheets would double and halt the system. WE BE JAMMIN'
This was a good thing because I was able to see this issue and it's literal tracks. As you can see, there is a BAND of magenta coming off the ITB. This isn't just some dusting of toner poofing from the end. It looks like its being written to the drum or rather the drum isn't being cleared near the end?

Sticking to principles, I'm assuming the drum becomes charged, the Writing Unit exposes the drum thus reversing the charge in non-image areas and toner then adheres to everything else. That might be simplifying it, but I'm sure you get what I mean.
It's a guess that this area isn't being "written" correctly and carrying toner to a place that it doesn't belong. Again, thank God for jams. LOL
It's clearly a solid band of magenta toner and none of the other colors are a problem nor is quality. Machine is running like it doesn't care... other than consuming magenta like it's candy.
Any thoughts on this new hypothesis?

This means if you do panic stop machine test M drum will has that band?

I would go for developing unit replacement right after drum and charge unit replacement does not give results.
You lost me about half way through.
If it was the laser causing this issue by writing that band of image (on digital devices the laser writes the text/image, NOT the white areas), the laser would have to be consistently ON when the beam reached the one end, which seems very unlikely to me. Usually with lasers, the fault you get is light NOT leaving the laser, usually obstructed by toner, or dust, or a failed laser diode, or a failed mirror motor ... many of these things will code out the machine. If it passes a Auto Color Calibration, the laser isn't it.
In my opinion it's got to be the magenta developing unit dumping, or the magenta drum not cleaning, or a rusting charge grid. In either case the toner spray will contaminate the primary charge grid, making it worse. =^..^=
If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Simply put, I already swapped the drum to see if it would do the same thing. I don't know if it was creating the same conditions, but the build-up on the 2nd Transfer definitely occurred. The band is perfect and one could assume a mechanical defect rather than just a minor quality flaw with something else. Imaging was a guess, but like you said, that would code out (I kinda figured it would).
I'm reaching for the answer and SLOWLY getting to PERFECTION. LOL
AND I already thought of the coronas, got a full set of them. ;-)
I'll swap out the magenta and replace it with a new one. As for the drum itself, there isn't anything visible on it that would suggest its failing. We'll see what happens next...
Thanks!
Yes, I already thought of the coronas. Got a set and a drum for the Magenta if all else fails. However, like I have explained, I swapped the drum out already to test the drum theory. Similar results.
I'm going with the corona and see if the problem lies there...
Thanks!
HMM, on the drum itself? That I don't know. I would need to look closer at that and would prove it is closer to the source of the problem.
What I do know, is the band is visible on the ITB. I would assume that the drum would have this as well if the machine panics...
I'm going to replace the corona to see if it's a charging issue to the drum.
Thank!
