Black drum potential is low , I think the shutter is not opening on the potential sensor. Where is the shutter located ?

Re: SPC messgae on C6530
The drum potential sensors are mounted on the metal bracket that swings down over the developing unit(s). There is a plastic snap release at the rear that allows each bracket to swivel up towards the front. No major disassembly of the imaging drawer is required (not that that stopped me the first time).
Which one needs cleaning? Check the following locations for abnormal sensor readings: 05-2780-0, 1, 2, 3 and 08-2560-0, 1, 2, 3. Normal values = 0. Abnormal values = 2 or 3).
Clean SPC for the desired color, and check that shutter works properly. To reset error: 08-2560-0, 1, 2, 3 set to 0.

Re: SPC messgae on C6530
Black Cat , Thank you for the information.
I was able to get rid of the SPC Message it took two tries. However The original issue is still the same .
I am getting shadows in the middle of the page on Black, Cyan and Magenta and the unit will not run simulation 2742 , it does run other simulations . I thought it was because of that SPC code
I changed all of the grids but not the charge corona saw tooth. Any reason you can think of that it wont run that sim ?Comment

Re: SPC messgae on C6530
I will print these on the unit when I get back that way. Probably Wednesday , Do you know where I might be able to pick up a used drum unit for this model ? I need the small wire harness between the end of the unit and the discharge lamps for the yellow unit. I pulled a lead out trying to get the connector off.
Also I am having trouble identifying the "clip" to lift the drum potential rails up. Not a great pic in the SM or Parts book. When I slide the drums out it looks like the shutters are already open so I cleaned the sensors. , none of them moved freely and I was not about to force them . Is that normal that they would be open ? Did I mention it was 3 (K) that had the error ? Thank you again for your assistanceComment

Re: SPC messgae on C6530
It is a miniscule connector. I'll look to see if I have anything.
You wont be able to see the potential control sensors or shutters very well until you swing the bracket up. There's a feature toward the right side of where the bracket touches the rear white plastic. press down with a small flat blade on the white plastic catch and it releases easily. You'll kick yourself once you figure it out.
It's kinda hard to describe. =^..^=If you'd like a serious answer to your request:

Re: SPC messgae on C6530
Black Cat , not sure how to attach files with this format , Hope this works if not please PM me @ wild140sd@yahoo.com and I can send that way .
The samples don't show the shadow as well as expected . best in black where you can see the middle is darker than the edges.
Any luck coming up with that small harness ?Comment

Re: SPC messgae on C6530
In the last day, I saw a thermistor with the right connector that you could splice onto your harness. The problem is, my fragmentary memory won't recall where I saw it. If you want the connector (and if I can find it again), PM to me a destination mailing address.
That's really crappy image quality. Were it me, I would start by cleaning the laser slit glasses. Then I would examine the 4 mag rollers to determine if you have good developer coverage on the roller. Between cleaning the laser slit glasses and changing developer, then doing a color calibration, that should resolve most of your quality issues. =^..^=If you'd like a serious answer to your request:

Re: SPC messgae on C6530
I agree with backcat i would also check the drum counts and do all epu kits, looks like charge grids and sawtooths are really dirtyComment

Re: SPC messgae on C6530
Thank You Luther and Black cat again for your advice , I did replace the grids. but not the saw tooths yet. I have them, so that is next. The DV "brush" does not look weak on any of the DV units. One of my concerns is it will not run the 2742 simulation , I thought it was because of the SPC message but that was reset and it still does not run. It is suppose to go into a "WAIT" cycle and run the calibration but this unit does nothing. The drum potential reading on black is low.
I swapped the yellow drum for black but that did not help .Last in the mix of all this and to compound the issue I pulled a lead out of the very small connector on the yellow drum unit discharge lamp. So I am looking for either that small harness or just a connector that size I can splice back in.
Black Cat , My e-mail is wild140sd@yahoo.com if you want to PM me with your e-mail address I can send you my physical address to send the connector if you can find one. Thank You Both againComment

Re: SPC messgae on C6530
All ,grids and saw tooth's have been replaced and it did not change , I was able to run a calibration through the user mode for copy, 300dpi and 1200 dpi , it made black a little better but not the colors. I still can not make 05-2742, Other things that don't seem to work are the counter codes for resetting life counts in 08, and under user there is suppose to be a way of entering a user service mode but that's not there either. I think I have ruled out everything drum related , Still can not figure out how to release the drum potential sensor holder so it can pivot up. I have attached pics so if anyone can better direct by drawing an arrow that would be great !
I was able to print a page using S9 mode and the developer counts for each of the consumables is no more than 67K , of course that could just mean that counters were reset but parts not changed . The unit has 1,8 mill plus on it.
I can also be fighting bad DV but the DV brushes look OK or after market toner .
I have the C6560 manual , hard to believe the codes and way of doing things are that much different ,
Last do you know what the default admin code is ?

Re: SPC messgae on C6530
The software side of the eS6560CT is vastly different than the 6530C. Toshiba transitioned from 3 digit simulation codes on the 6530 to 4 digit simulation codes on the 6560. None of the codes are the same. And the Service User Interface is not on the 6530, never was.
The picture is a little small, but if you use a small flat blade screwdriver, gently pry tip toward the back:

Re: SPC messgae on C6530
Down the Toshiba C6530 rabbit hole again today, I am getting an education on this one.
Thank You Black cat for the picture I was able to lift the stay over the drum but the drum surface potential is facing out other than what looks like a drum thermistor I don't see another sensor in that area.
Now I have the correct manual so simulations make a lot more sense , However the more I learn about this unit the more questions I have.
#1 , I discovered Simulation 08-2561 , drum surface potential control setting was already disabled which make sense because when you enable it and try to run 05-396 Automatic init of image quality , you get a SC-CE20 which indicates a bad image quality sensor issue ( Shutter or Sensor ) , The shutter moves free have not tested the solenoid in simulation yet.
If you disable 08-2561 and run 05-396 you get an drum potential K error ( Top row so not the drum potential shutter not opening)
All readings in 05-390 are below the 628 threshold, Y= 403, M=353, C=391,K=354 so they are all low and no one of them is far from the other.
running 05-396 with both 08-556 and 08-2561 disabled , which is what you are suppose to do with low reading and the unit does nothing goes right back to "A" as soon as you hit start.
Basically none of the tests that you can run for the conditions that are happening seem to give you a definitive answer to the problem.
Writing this I noticed in the book manual adjustments for back grounding , should I take a shot at those seeing as 08-2561 is already disabled ?
I also think I am dealing with a different issue , Attached are sample prints of simulation 04-270 , the banding is on the transfer belt when I open the unit , this is before and after the transfer belt and transfer cleaning blade have been replaced. It almost seems like the transfer belt cleaning blade is not wiping the belt with enough pressure to clean the belt. But it also does not explain where the banding is coming from.
When the blade assembly is put into place are the white holders on top suppose to lock it in or does it float and another cam lifts it into place and add the pressure ? Toshiba Samples.pdfToshiba Samples.pdf
Thanks all who might have an answer.Comment

Re: SPC messgae on C6530
I don't like the way the yellow patch bends. I'm trying to visualize how the yellow patch might warp.
The primary transfer belt might be tracking off to one side ... but that would affect the other colors too. Perhaps the primary belt frame is loose/wobbling at the yellow/magenta end, causing the background in your scans. The belt unit rests on four posts: perhaps one is bent or not lined up?
Or the yellow drum unit:Is it seating in the imaging drawer securely? If it were wobbling it might nudge the belt or shift against the primary transfer belt from below. Have you swapped the yellow drum assembly with the black temporarily? What changes?
I also don't like the absence of the black patch. Do you get black images of internal reports or internal test patterns? If you swap out drum potential sensors, do the errors change? =^..^=If you'd like a serious answer to your request:
