A:Answer The Brother HLL8360CDWT supports up to 43 lb. bond paper. Some glossy papers that are 80 lb. may be "TAG" Transformation Paper Type, which is equivalent to 35 lb. bond paper. Glossy paper should be printed from the Manual Feed Slot with the back cover open. Printing glossy paper with the back cover closed can cause damage to your machine as well as print quality issues such as smudges, toner rubbing off, etc. Only print in duplex if glossy paper is between 16 - 28 lb.
