J75 colour issues...

[wonderings]

So we have a Xerox J75 that is around 6 months old, 200,000 clicks on it. Getting the machine it was fantastic, a HUGE step up from the DC260. Colour held very well, registration was amazing and the tools for aligning back to front were fantastic as well. After about 4 months we started having issues. A real motley looking colour, no longer was a solid or screen coming out smooth as it did in the beginning. Xerox service is telling us we will have to start playing with image transfer settings. Now I would need to adjust difference transfer settings for each job individually even though it is the same stock. Had to make a setting for a job with lots of black, had to do a different setting with a job with solid greens, again all on the same 14pt stock that we have been using from day 1 when we got the J75.

Anyone else having issues like this? I have trouble believing that you would have to make and have so many profiles for paper that is rated for use on this machine. It is not limited to 14pt stock, we have had issues with 12pt and 10pt.

Has the transfer belt and the second BTR been replaced?

They have been ripping everything out of the insides. I know the transfer belt has been replaced, not 100% on the BTR. We were having serious registration issues, which now seem to be thankfully resolved.

Our C75 has had similar issues. They were fixed by the technician who replaced the 2nd bias roller, and all four developer housings.

Thanks, I will ask our tech about that. I think though that the developer housings have been changed, not sure about the 2nd bias roller. I will definitely be making a note of that to ask them.

Our techs are good, but sometimes you have to be insistent. When we first got our machine, I ran some jobs with solids, and kept those to compare to, in case they tried to tell me nothing was wrong. We started noticing blacks that were splotchy and not covering very well, even on smooth gloss sheets. At first they acted like it was the fault of the file I was printing from, but then I showed them a sample of that file run a few weeks prior. At that point they replaced parts until the problem was fixed.

Oh we have been. The techs have been good in the past, thats one of the reasons we stayed with Xerox. We keep samples from every job, so were able to show how it was 6 months ago and how we can't match that now, which was one of the selling points. We are going to be having a talk with some higher ups soon, can only go so far with the techs.
