I have a C6500 machine that is going to drive me postal pretty soon.
The short history of this problem....
My boss went in to do some colour adjustments, customer was getting reds instead of orange. Relatively minor and simple procedure, it is something both he and I have done hundreds of times in the past. Drum potential and Gamma adjust followed by a calibration usually resolves this problem, and if not, we take further measure to replace the drum, charge wire or developer/d-unit in any given order. Most of the time, we are done in a few minutes.
What happens after these minor adjustments is when going back out of tech rep into the user mode, the machine will throw C2411, abnormal TCR.
After restarting the developer in the machine, the boss eventually replaced the PRCB and the problem was fixed.
A little over a week later, same colour problem. I go in and do this adjustment, and like the boss, the machine tosses another 2411. At this point, some consulting with the boss, we make the decision to replace the dev units (they were about 400K, so the whole lot replaced) and restarted the devs. And like before, this did not resolve the problem and I replaced the PRCB again, and this fixed the problem.
Today, this colour issue arose yet again. WIth some apprehension, I tried other ways to get the machine to properly print the job without doing the previous adjustment, but not even recalibrating the machine provided the results wanted, the colour just refused to blend correctly. So I tried yet again, drum potential and gamma adjust.
Neither of those two adjustments have any bearing on TCR, and yet, the machine tosses another 2411.
Some inspection in tech rep to display the TCR values, all showed 0000.
Again I will be replacing the PRCB again in the morning.
3 times in as many weeks, with brand new boards, this is getting a bit rediculous. My thoughts are that something else must be at fault. A talk with tech support has given me a lead on 12V supplied, though he has doubts since I am not getting any error event elsewhere, specifically the toner density sensor on the registration assembly.
Has anyone else had this kind of game happen to them, and if so, what did you do to resolve it, aside from wasting money replacing the PRCB once every week or so?
It should also be noted that the machine was capable of producing the correct colour in tech rep, providing the halftone values for each CMYK, yet when the job was spooled, the colour was incorrect. A preview of the job through command workstation showed the colours as expected, yet when printed, the colour was incorrect.
For the most part, the machine was operating normally otherwise.
