Dual Process for Reflow

Hello Reflow Masters;

I'm using an Omniflo-10E reflow oven. Due to high demands of our production in lead free process, can I use my existing leaded line as an native? Does this option affect the lead contamination of the solder in Pb-Free to go beyond acceptability as per RoHS Annex 7 directive? http://www.apcmedia.com/salestools/RLIE-6QJP6V_R0_EN.pdf

I believe that we are exempted with this: 7b) RoHS Content It is prohibited to market electrical and electronic devices containing higher than allowed levels of the environmentally hazardous substances listed in RoHS. Selling appliances containing these substances is prohibited at all levels of trade.

For instance, 8 hours running on leaded followed by lead-free and back to leaded process again, with just changing the recipe per process.

Any thoughts?
