There are a lot of researching in progress for improving the quality of 2nd BTR and there is a new part no. just for tests for the moment.
Our Versant 2100 is printing lines/marks when using duplex print. This happens because the 2nd BTR can't clean the waste/extra toner before printing the other side. It's far worse on coated paper than uncoated paper.
We are currently switching between 2nd BTR's. We use one 2nd BTR for coated paper and another one for uncoated paper. For coated paper we're using Xerox Colour Impressions Silk and the 2nd BTR only lasts for about 10K impressions. Coated paper is too sensitive for the 2nd BTR roller. The 2nd BTR roller is made of soft rubber/plastic and appears to be pretty weak/fragile as lines/marks appear on the roller after a few uses. Other printers usually don't have problems like this. Fx. Xerox C75. They use softer 2nd BTR rollers that don't get damaged like the ones on the Versant series.
This states that the Versant printers have a huge production fault with 2nd BTR's. Because they basically can't print on coated paper. Xerox must produce a new version of the 2nd BTR's because the Versant machines clearly aren't working as they should be.
Does anyone know if a new type of 2nd BTR is in the making or on the market?
