Xerox (Versant) 2nd BTR streaking marks work around

[pippip]

Hi,

This topic crops up alot on here amongst Versant owners (my V80 being on of them). Just thought I'd share my workaround.

Problem - 2nd Btr creates drag lines from waste toner. Occurs mainly on coated stocks and results in 2nd Btr needing to be constantly replaced way before its due. More common with less coverage on jobs.

Solution - As the problem rarely occurs when larger coverage is on the sheets I had an idea. I placed solid bars (C100 M100 Y100 K100) on each end of the sheet as per image below. I've ran a number of larger volume coated jobs since and they have been perfect with no marking at all. I'm on contract so extra toner doesn't bother me cost wise. Only problem is I have to manually add these in indesign so imposing jobs is a problem still.

I was googling this to see if another solution was about and I stumbled upon someone with a similar solution on a xerox support site so I'm confident I didn't just fluke it myself. They explain why the solution works better.

2ND BTR Issue SOLUTION

We for months have been having issues with color streaking due to buildup in the 2nd BTR unit. We had a long stading (several months) service call with Xerox to try and resolve it, that reached the hands of technicians, specialists and management with no solution provided. In fact, despite the...

Why are you not changing out the 2nd BTR.

Oh I do, always have spares and they showed me how to do it myself but I've had it where I've only gotten 10k and its gone again.
The above work around just means I no longer have to watch the machine and constantly check the sheets.

Xerox had changed the 2nd BTR to a softer roller which meant it was more prone to scratches. When my engineer came round to change it, he told me that they were being called out a lot for this reason. 90% of the paper I use is silk and this causes the problem, especially on the heavier weights. I went through a phase of changing 3 2nd BTR rollers within 1 month!!!!!!!
Problem doesn't happen as much nowaday, but thanks for the tip!!!!
