Whenstoringpaper,observethefollowingprecautions:
•Paperisparticularlysensitivetomoisture,andshouldbekeptawayfrom
dampareas.
•Thepackagingthatthepaperissoldinisdesignedtoresistmoisture.Keep
paperinitsoriginalpackaginguntilyouarereadytouseit.Returnany

•Storepaperflat.
•Avoidstoringpaperonthefloor,becausefloorsareoftendamp.
•Donotpositionthepaperwhereitmightbecomecurledorcreased.
•Donotstorepapervertically,orinexcessivelyhighstacks.
