Re: 3551ci background problem
Nevermind, I understand now. Thanks.

Re: 3551ci background problem
e.g.
1111 1111 1111 0000
last 4 calibrations failed
0000 1111 1111 1111
calibration 12 -16 failed
If the ID sensors don`t work, you must get
0000 0000 0000 0000 instead of 0011 1111 1111 1111
and U468 shows "0" instead of "16383"
Maybe we have problem with Dv stations because of DV powder stress inside.
We are talking about 35ppm system.
Needed time for each page = 60 seconds/ 35ppm
~1,7 seconds/ page during multiple printing
Now you can check needed time at your system:
U157 * 60/ U158 will show you the needed time/ page at your system.
We have had systems with values > 6 seconds and we got faint images or background.
After running developer refresh, system works well for a few days, but problem came back.

Re: 3551ci background problem
I went back today and the machine finally printed with a blue background while I was there. This turned out to be the call from hell because it's in a medical office that's very busy and they rely on this one copier to do everything and they kept asking me if they could make a copy/scan/fax every 5 minutes. Then I got in a hurry and the fuser slipped out of my hand and it broke the exit gate off. I had to go back to the shop and grab another one. Whew!!!
After all of that I replaced the cyan DV, DR and PCR. It worked fine after that but we'll have to see as this has been a very intermittent problem.
Edit: I'm never gonna rush a job again. They'll just have to get pissed off or whatever. No more rushing. This is one of my bigger accounts as they have about 10 different locations on the Gulf Coast.Adversity temporarily visits a strong man but stays with the weak for a lifetime.Comment

Re: 3551ci background problem
KYO,
The information you shared with me is very informative. Eye opening, really. But I don't see that detailed of information in the Service Manual. How did you discover this? Just curious.Adversity temporarily visits a strong man but stays with the weak for a lifetime.Comment

Re: 3551ci background problem
I went to AlphardI class training in Dallas, and I'm pretty sure this never came up.
I would have remembered. =^..^=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.

Re: 3551ci background problem
I plan on doing some tests and I'm gonna make the machine purposefully fail calibration and check it against the information that KYO provided. It is interesting because you can basically eliminate certain parts/supplies as being the problem by reading the numbers that KYO posted.Adversity temporarily visits a strong man but stays with the weak for a lifetime.Comment

Re: 3551ci background problem
That's what it looked like to me at first. But it's really not that complicated. And I can tell you this with certainty - everything KYO said is true.
Even after understanding how to read/acquire the data, it took a minute for me to get the big picture.
At the heart and soul of the color copier is the calibration process. Who wouldn't want to know if the last 16 calibrations failed or passed? That's only the starting point of the big picture. The next step is to look at other data such as Service Call Log on the Event Log. That can help further isolate as to why calibration failed.
Of course, a very experienced tech has probably seen just about everything and they'd have the problem fixed before I could convert V-correction to binary. Still, it's another tool in the tool bag.Adversity temporarily visits a strong man but stays with the weak for a lifetime.Comment

Re: 3551ci background problem
By the way, I officially switched over from using the internal test charts in the machine to the ones that blackcat uses. They simply show more imperfections.Adversity temporarily visits a strong man but stays with the weak for a lifetime.Comment

Re: 3551ci background problem
just print from a usb drive?
Yes calibration huge mystery to many of us !
Also on my mind a question:
Heres the latest Kyocera out in Europe: TASKalfa 3554ci
If this is the FOURTH generation of this model design.. shouldn't it be utterly bulletproof and every flaw and design hardware/software error corrected thus a now super reliable copier?Comment
