all, I regularly run a 75# postcard, in SMALL quantities... lately, a fefw have gotten big, mostly due to office errors-good times.... this paper is pretty dry and porous. seems like it should be fine... if I run for a long time, my external rollers are CAKED! made a substrate setting based on what I Was told the paper is...and measurements. but im missing something. looking through the recommended list, I dont see anything. any of you use a 75# postcard and have some good baseline settings for me to try?
