Hi,
This is my first post so first of all "Hello!" and thanks for any help in advance. I am currently pulling my hair out with an issue one of my companies is having and it is costing us hundreds of pounds a day at the moment.
About 6 weeks ago we noticed that on some of the colour print outs we do that the black was dropping out. For example where it should have been say 90 percent black it was coming out at 50 percent black. The it would just change back again and be ok. We have a creo CX print server and a Xerox dc700.
We have logged various calls with Xerox and the engineers thought it was the RIP. The rip therefore was reinstalled including Operating system, upgrading all firmware and software on printers and Rip but still the issue persisted.
We started putting a black to white grey scale bar (so that it goes from black to grey to whitein 10% increments) on the top of one of the colour images and you can see when the printer works that the gradation drops steadily in 10% increments. Then randomly it just drops out and it goes from 100% black to 50% grey (rather than 90%) etc. And this happens with the same ripped print job (we are using a nigella Lawson image as we print calendars).
We have tried swapping cables, changing toner, fuser unit, settings on the print jobs. Their just seems no rhyme or reason and it just changes intermittently.Also should have said that if I photocopy the correct print out when the printer is printing things greyer than normal it works which kind of makes me think its the board on the printer that has the Scitex port or something as the creo has been reinstalled and the photocopier is working ok. but that's just my deduction and may be incorrect. it always sounded like a hardware issue to me but the engineers so far have disagreed.
I also have to say that the current Xerox support has been significantly lacking and I don't know how to escalate this issue as it has been going on too long. We are now going in to the printing season.
Our Xerox ref is 3371575
if anyone has any suggestions then please help!!!
Many thanks,
Paul
